AcousticProperties |
[inherits X3DAppearanceChildNode]
AcousticProperties specifies the interaction of sound waves with characteristics
of geometric objects in the scene. Acoustic coefficient values are expected to fully
account for physical and structural characteristics of associated geometry such as
width, height, thickness, shape, softness and/or hardness, and density variations.
Hint: AcousticProperties must have a parent Appearance node, and only affects geometry
within the same Shape.
Hint: proxy geometry for acoustic response can be far simpler than geometry needed for
visual rendering.

Anchor |
[inherits X3DGroupingNode, implements X3DUrlObject, X3DVisibleObject]
Anchor is a Grouping node that can contain most nodes. When the user selects any
of the geometry contained by the Anchor node, the browser either jumps to another
viewpoint (similar to HTML bookmark) or else loads content (such as X3D, an image
or HTML) specified by the url field.
Newly loaded content completely replaces current content, if the value of parameter
field indicates using the same window.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: when parent node is LoadSensor, apply containerField='children' (X3Dv4) or containerField='watchList'

DirectionalLight |
[inherits X3DLightNode]
DirectionalLight defines parallel light rays that illuminate geometric shapes.
Lighting illuminates all geometry except lines and points. By default, light scope
only illuminates peer geometry and children nodes within the scene graph hierarchy.
No source location is needed since rays are parallel from an infinitely distant source.
DirectionalLight nodes do not attenuate with distance.
Lights have no visible shape themselves and lighting effects continue through any
intermediate geometry.
Hint: animate direction to simulate time-of-day sunlight effects.
Hint: the bound NavigationInfo controls whether headlight is enabled on/off.
Interchange profile
Hint: light might not be scoped by parent Group or Transform. |

ElevationGrid |
[inherits X3DGeometryNode]
ElevationGrid is a geometry node defining a rectangular height field, with default
values for a 1m by 1m square at height 0.
Vertices corresponding to ElevationGrid height values define quadrilaterals, which
are placed above or below a flat surface.
Hint: the height array defines (xDimension-1)*(zDimension-1) quadrilaterals.
Warning: generated quadrilaterals can be nonplanar. Tessellation splits quadrilaterals into
triangles along seam starting at initial vertex of the quadrilateral and proceeding
to opposite vertex.
Hint: positive direction for normal of each triangle is on same side of the quadrilateral.
Triangles are defined either counterclockwise or clockwise depending on value of ccw
field.
Hint: ElevationGrid can contain Color|ColorRGBA, Normal and TextureCoordinate nodes.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: for advanced extensibility, authors can substitute a type-matched ProtoInstance
node (with correct containerField value) for contained node content. |

[normal accessType inputOutput, type SFNode singleton, NULL node] [X3DNormalNode]
Single contained Normal node that can specify perpendicular vectors for corresponding
vertices to support rendering computations, applied according to the normalPerVertex
field.
Hint: useful for special effects. Normal vector computation by 3D graphics hardware is
quite fast so adding normals to a scene is typically unnecessary.
Warning: normal vectors increase file size, typically doubling geometry definitions. Normal
vectors are rapidly computed at run time by GPUs and thus are rarely needed in model
files if no special effects are expected. |

Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| xDimension |
[xDimension accessType initializeOnly, type SFInt32 CDATA "0"] (0,+β)
Number of elements in the height array along X direction.
Hint: total horizontal x-axis distance equals (xDimension-1) * xSpacing.
Warning: xDimension < 2 means that ElevationGrid contains no quadrilaterals. |
| zDimension |
[zDimension accessType initializeOnly, type SFInt32 CDATA "0"] (0,+β)

rows and zDimension columns.
Hint: height array values are given in row-major order from left to right along X axis,
then back to front along Z axis.
Warning: height array values are not retained or available at run time since a browser is
permitted to condense geometry.
Hint: this field is not accessType inputOutput since X3D browsers might use different
underlying geometric representations for high-performance rendering, and so output
events are not appropriate. |
| set_height |
[set_height accessType inputOnly, type MFFloat CDATA #FIXED ""]
Grid array of height vertices with upward direction along +Y axis, with xDimension
rows and zDimension columns.
Hint: height array values are given in row-major order from left to right along X axis,
then back to front along Z axis.
Warning: it is an error to define this transient inputOnly field in an X3D file, instead
only use it a destination for ROUTE events.
Hint: this field is not accessType inputOutput since X3D browsers might use different
underlying geometric representations for high-performance rendering, and so output
events are not appropriate. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| creaseAngle |
[creaseAngle accessType initializeOnly, type SFFloat CDATA "0"] [0,+β)
creaseAngle defines angle (in radians) for determining whether adjacent polygons
are drawn with sharp edges or smooth shading. If angle between normals of two adjacent
polygons is less than creaseAngle, smooth shading is rendered across the shared line
segment.
Hint: creaseAngle=0 means render all edges sharply, creaseAngle=3.14159 means render all
edges smoothly.
Hint: radian units for angular measure https://en.wikipedia.org/wiki/Radian |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.

Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices. |
| containerField |
[containerField type NMTOKEN "geometry"]
containerField is a field-label prefix indicating this node's field relationship

Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'

Extrusion |
[inherits X3DGeometryNode]
Extrusion is a geometry node that sequentially stretches a 2D cross section along
a 3D-spine path in the local coordinate system, creating an outer hull.
Scaling and rotating the crossSection 2D outline at each control point can modify
the outer hull of the Extrusion to produce a wide variety of interesting shapes.
Warning: take care to avoid defining parameter combinations that create self-intersecting,
impossible or inverted geometry.
Hint: Extrusion https://en.wikipedia.org/wiki/Extrusion

Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions |
| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| crossSection |
[crossSection accessType initializeOnly, type MFVec2f CDATA "1 1, 1 -1, -1 -1, -1 1, 1 1"]
The crossSection array defines a silhouette outline of the outer Extrusion surface.
crossSection is an ordered set of 2D points that draw a piecewise-linear curve which
is extruded to form a series of connected vertices.
Hint: the crossSection array can be open or closed (closed means that endpoints are coincident).
Hint: number of values must all match for 3-tuple spine points, 2-tuple scale values,
and 4-tuple orientation values.
Warning: if the order of crossSection point definition does not match clockwise/counterclockwise
setting of ccw field, then self-intersecting, impossible or inverted geometry can
result!
Warning: avoid self-intersecting polygon line segments, otherwise defined geometry is irregular
and rendering results are undefined (especially for end caps). |
| orientation |
[orientation accessType initializeOnly, type MFRotation CDATA "0 0 1 0"]
The orientation array is a list of axis-angle 4-tuple values applied at each spine-aligned
cross-section plane.
Hint: if the orientation array contains a single 4-tuple value, it is applied at all spine-aligned
crossSection planes.
Hint: number of values must all match for 3-tuple spine points, 2-tuple scale values,
and 4-tuple orientation values. |
| scale |
[scale accessType initializeOnly, type MFVec2f CDATA "1 1"] (0,+β)
scale is a list of 2D-scale parameters applied at each spine-aligned cross-section
plane.
Hint: number of values must all match for 3-tuple spine points, 2-tuple scale values,
and 4-tuple orientation values.
Hint: if the scale array contains one value, it is applied at all spine-aligned crossSection
planes.
Warning: zero or negative scale values not allowed. |
| spine |
[spine accessType initializeOnly, type MFVec3f CDATA "0 0 0, 0 1 0"]
The spine array defines a center-line sequence of 3D points that define a piecewise-linear
curve forming a series of connected vertices. The spine is set of points along which
a 2D crossSection is extruded, scaled and oriented.
Hint: the spine array can be open or closed (closed means that endpoints are coincident).
Hint: number of values must all match for 3-tuple spine points, 2-tuple scale values,
and 4-tuple orientation values.
Warning: special care is needed if creating loops or spirals since self-intersecting, impossible
or inverted geometry can result!
Warning: ensure that spine segments have non-zero length and are not coincident with each
other.
Hint: if a spine is closed (or nearly closed) then the inner diameter usually needs to
be greater than the corresponding crossSection width. |
| beginCap |
[beginCap accessType initializeOnly, type SFBool (true|false) "true"]
Whether beginning cap is drawn (similar to Cylinder top cap).
Warning: since this field has accessType initializeOnly, the value cannot be changed after
initial creation. |
| endCap |
[endCap accessType initializeOnly, type SFBool (true|false) "true"]
Whether end cap is drawn (similar to Cylinder bottom cap).
Warning: since this field has accessType initializeOnly, the value cannot be changed after
initial creation. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
The ccw field indicates counterclockwise ordering of vertex-coordinates orientation.
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| convex |
[convex accessType initializeOnly, type SFBool (true|false) "true"]
The convex field is a hint to renderers whether all polygons in a shape are convex
(true), or possibly concave (false). A convex polygon is planar, does not intersect
itself, and has all interior angles < 180 degrees.
Hint: concave is the opposite of convex.
Warning: concave or inverted geometry may be invisible when using default value convex=true,
since some renderers use more-efficient algorithms to perform tessellation that may
inadvertently fail on concave geometry.
Hint: select convex=false (i.e. concave) and solid=false (i.e. two-sided display) for
greatest visibility of geometry.
Hint: convex polygon https://en.wikipedia.org/wiki/Convex_polygon
Hint: tessellation https://en.wikipedia.org/wiki/Tessellation |
| creaseAngle |
[creaseAngle accessType initializeOnly, type SFFloat CDATA "0.0"] [0,+β)
creaseAngle defines angle (in radians) where adjacent polygons are drawn with sharp
edges or smooth shading. If angle between normals of two adjacent polygons is less
than creaseAngle, smooth shading is rendered across the shared line segment.
Hint: creaseAngle=0 means render all edges sharply, creaseAngle=3.14159 means render all
edges smoothly.
Hint: radian units for angular measure https://en.wikipedia.org/wiki/Radian |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.
|
| set_crossSection |
[set_crossSection accessType inputOnly, type MFVec2f CDATA #FIXED ""]
The crossSection array defines a silhouette outline of the outer Extrusion surface.
crossSection is an ordered set of 2D points that draw a piecewise-linear curve which
is extruded to form a series of connected vertices.
Warning: if the order of crossSection point definition does not match clockwise/counterclockwise
setting of ccw field, then self-intersecting, impossible or inverted geometry can
result!
Warning: it is an error to define this transient inputOnly field in an X3D file, instead
only use it a destination for ROUTE events.
Hint: this field is not accessType inputOutput since X3D browsers might use different
underlying geometric representations for high-performance rendering, and so output
events are not appropriate. |
| set_orientation |
[set_orientation accessType inputOnly, type MFRotation CDATA #FIXED ""]
The orientation array is a list of axis-angle 4-tuple values applied at each spine-aligned
cross-section plane.
Hint: if the orientation array contains a single 4-tuple value, it is applied at all spine-aligned
crossSection planes.
Hint: number of values must all match for 3-tuple spine points, 2-tuple scale values,
and 4-tuple orientation values.
Warning: it is an error to define this transient inputOnly field in an X3D file, instead
only use it a destination for ROUTE events.

Warning: zero or negative scale values not allowed.
Warning: it is an error to define this transient inputOnly field in an X3D file, instead

| set_spine |
[set_spine accessType inputOnly, type MFVec3f CDATA #FIXED ""]
The spine array defines a center-line sequence of 3D points that define a piecewise-linear
curve forming a series of connected vertices. The spine is set of points along which
a 2D crossSection is extruded, scaled and oriented.
Hint: the spine array can be open or closed (closed means that endpoints are coincident).
Hint: number of values must all match for 3-tuple spine points, 2-tuple scale values,
and 4-tuple orientation values.
Warning: special care is needed if creating loops or spirals since self-intersecting, impossible

| containerField |
[containerField type NMTOKEN "geometry"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

GeoElevationGrid |
[inherits X3DGeometryNode]
GeoElevationGrid is a geometry node defining a rectangular height field, with default
values for a 1m by 1m square at height 0. Vertices corresponding to GeoElevationGrid
height values define quadrilaterals, which are placed above or below a curved geospatial
surface using geographic coordinates.
Hint: the height array defines (xDimension-1)*(zDimension-1) quadrilaterals.
Warning: generated quadrilaterals can be nonplanar. Tessellation splits quadrilaterals into
triangles along seam starting at initial vertex of the quadrilateral and proceeding
to opposite vertex.
Hint: positive direction for normal of each triangle is on same side of the quadrilateral.
Triangles are defined either counterclockwise or clockwise depending on value of ccw
field.
Hint: GeoElevationGrid can contain GeoOrigin, Color|ColorRGBA, Normal and TextureCoordinate
nodes.
Hint: insert a Shape node before adding geometry or Appearance.

| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]

solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.

| creaseAngle |
[creaseAngle accessType initializeOnly, type SFDouble CDATA "0"] (0,+β)
creaseAngle defines angle (in radians) for determining whether adjacent polygons
are drawn with sharp edges or smooth shading. If angle between normals of two adjacent
polygons is less than creaseAngle, smooth shading is rendered across the shared line
segment.
Hint: creaseAngle=0 means render all edges sharply, creaseAngle=3.14159 means render all
edges smoothly.
Warning: note type double, unlike ElevationGrid creaseAngle.
Hint: radian units for angular measure https://en.wikipedia.org/wiki/Radian |
| colorPerVertex |
[colorPerVertex accessType initializeOnly, type SFBool (true|false) "true"]

| isActive |
[isActive accessType inputOutput, type SFBool #FIXED ""]
Select geometry by activating the pointing device (for example, clicking the mouse)
to generate isActive events. Output event isActive=true is sent when geometry is selected
(for example, when primary mouse button is pressed), output event isActive=false is
sent when geometry is deselected (for example, when primary mouse button is released).
Warning: it is an error to define this transient outputOnly field in an X3D file, instead

GeoViewpoint |
[inherits X3DViewpointNode]
GeoViewpoint specifies viewpoints using geographic coordinates.
GeoViewpoint can contain a GeoOrigin node.
Since GeoViewpoint must navigate smoothly inside a curved geographic coordinate system,
it includes both Viewpoint and NavigationInfo attributes.
Hint: alternatively can use GeoLocation or GeoTransform as parent of a Viewpoint node
to orient geospatial views.
Hint: include <component name='Geospatial' level='1'/>
Hint: when a GeoViewpoint node is bound, it also overrides the currently bound NavigationInfo
node in the scene and controls user navigation for smoother geospatial interaction.
Hint: Background, Fog, GeoViewpoint, NavigationInfo, OrthoViewpoint, TextureBackground
and Viewpoint are bindable nodes, meaning that no more than one of each node type
can be active at a given time.
Hint: GeoViewpoint OrthoViewpoint and Viewpoint share the same binding stack, so no more
than one of these nodes can be bound and active at a given time.
Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint,
TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
Avoid this authoring pattern.
Warning: do not include GeoViewpoint OrthoViewpoint or Viewpoint as a child of LOD or Switch,
instead use ViewpointGroup as parent to constrain location proximity where the viewpoint
is available to user.
Warning: GeoViewpoint navType and headlight fields were removed as part of X3D version 3.3,
authors can instead use a NavigationInfo node for those fields in prior X3D versions
3.0, 3.1 or 3.2. Upgrading such legacy scenes to version 3.3 or greater is preferred
and recommended.
Hint: Regardless of viewpoint jump value at bind time, the relative viewing transformation
between user's view and defined position/orientation is stored for later use when
un-jumping (returning to the viewpoint when subsequent viewpoint is unbound).
Hint: customizable design pattern for dedicated Viewpoint/NavigationInfo pair: <Viewpoint
DEF='SpecialView'/> <NavigationInfo DEF='SpecialNav'/> <ROUTE fromNode='SpecialView'
fromField='isBound' toNode='SpecialNav' toField='set_bind'/>
Warning: avoid having GeoLocation or GeoTransform as a parent or ancestor node of GeoViewpoint,

HAnimDisplacer nodes alter the shape of coordinate-based geometry within parent
HAnimJoint or HAnimSegment nodes. Displacer effects are scaled by the corresponding
weight field.
Hint: HAnimDisplacer can be used in three different ways:
(a) identify vertices corresponding to a particular feature in a parent HAnimSegment
node,
(b) represent a particular muscular action for a parent HAnimJoint node by displacing
corresponding HAnimHumanoid skin vertices in various directions (linearly or radially),
or (c) represent a complete configuration of coordinate vertices in parent HAnimSegment
or HAnimJoint nodes.
Example: in the case of a face, there might be a separate HAnimDisplacer node for each facial
expression.
Warning: allowed name suffixes include _feature, _action and _config.
Hint: multiple HAnimDisplacer nodes must appear consecutively inside parent HAnimSegment
for proper content validation in XML encoding.

| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| name |
[name accessType inputOutput, type NMTOKEN #REQUIRED]
Unique name attribute must be defined so that each HAnimHumanoid node in a scene
can be identified at run time for animation purposes.
Hint: this same name is a required name prefix for all other HAnim nodes within the HAnimHumanoid,
if more than one humanoid appears within a scene file.
Warning: name field is not included if this instance is a USE node, in order to avoid potential
mismatches.

| containerField |
[containerField type NMTOKEN "children"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

[bboxSize accessType initializeOnly, type SFVec3f CDATA "-1 -1 -1"] or [0,+β)
Bounding box size is usually omitted, and can easily be calculated automatically
by an X3D player at scene-loading time with minimal computational cost. Bounding box
size can also be defined as an optional authoring hint that suggests an optimization
or constraint.
Hint: can be useful for collision computations or inverse-kinematics (IK) engines.
Hint: precomputation and inclusion of bounding box information can speed up the initialization
of large detailed models, with a corresponding cost of increased file size.

Hint: the bounding box is displayed regardless of whether contained content is visible.
|
| visible |
[visible accessType inputOutput, type SFBool (true|false) "true"]
Whether or not renderable content within this node is visually displayed.
Hint: the visible field has no effect on animation behaviors, event passing or other non-visual
characteristics.
Hint: content must be visible to be collidable and to be pickable. |
| containerField |
[containerField type NMTOKEN (children|skeleton|joints) "children"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.

USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| name |

in the animation, equaling the number of sets of channel data rows present in the
values array. |
| frameDuration |
[frameDuration accessType inputOutput, type SFTime CDATA "0.1"] (0,+β)
frameDuration specifies the duration of each frame in seconds. |
| frameIncrement |
[frameIncrement accessType inputOutput, type SFInt32 CDATA "1"] [-β,+β)
frameIncrement field controls whether playback direction is forwards or backwards,
and also whether frames are skipped (for example, subsampled replay). For a single
animation step, the next frameIndex value equals (frameIndex + frameIncrement) modulo
frameCount.
Hint: note that setting frameIncrement to 0 prevents automatic advancement of frameIndex
and pauses animation of HAnimMotion node. |
| frameIndex |
[frameIndex accessType inputOutput, type SFInt32 CDATA "0"] [0,+β)
frameIndex indicates index of current frame. Note that frameIndex can be modified
whether the Motion node is enabled or not, and becomes effective when the next animation
cycle occurs. Thus the frameIndex value indicates the frame currently (or next) being
processed.
Hint: frameIndex starts at 0 and is no greater than (frameCount - 1). Values less than
0 are reset as 0. Values greater or equal to frameCount are stored as (frameCount
- 1). Thus the value of frameIndex shall be greater than or equal to zero, and less
than frameCount. |

| endFrame |
[endFrame accessType inputOutput, type SFInt32 CDATA "0"] [0,+β)
endFrame indicates final index of animated frame. Note that endFrame can precede,
equal or follow endFrame. The default endFrame value is reset to (frameCount - 1)
whenever frameCount is changed.
Hint: endFrame starts at 0 and is no greater than (frameCount - 1). |
| values |
[values accessType inputOutput, type MFFloat CDATA #IMPLIED]
values field contains all transformation values, ordered first by frame, then by
joint, and then by transformation Sets of floats in the values array matching the
order listed in joints and channels fields. |
| next |
[next accessType inputOnly, type SFBool (true|false) ""]
Send next output value in values array, using/updating various frame values as appropriate.
Hint: this input event will "wrap around" boundary of frame array, i.e. continue from
endFrame next to startFrame if necessary.
Warning: it is an error to define this transient inputOnly field in an X3D file, instead
only use it a destination for ROUTE events. |

elapsedTime is computed elapsed time since the Motion object was activated and running,
counting all traversed frames (as if frameIndex equaled 1) and multiplied by frameDuration,
cumulative in seconds.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead
only use it a source for ROUTE events.
Hint: elapsedTime is a nonnegative SFTime duration interval, not an absolute clock time.

[inherits X3DGroupingNode, implements X3DVisibleObject]
An HAnimSite node serves three purposes:
(a) define an "end effector" location which can be used by an inverse kinematics system,
(b) define an attachment point for accessories such as jewelry and clothing, and
(c) define a location for a Viewpoint virtual camera in the reference frame of an
HAnimSegment
(such as a view "through the eyes" of the humanoid for use in multi-user worlds).
Hint: HAnimSite nodes are stored as children of an HAnimSegment node.

ImageTexture |
[inherits X3DTexture2DNode, implements X3DUrlObject]
ImageTexture maps a 2D-image file onto a geometric shape.
Texture maps have a 2D coordinate system (s, t) horizontal and vertical, with (s,
t) texture-coordinate values in range [0.0, 1.0] for opposite corners of the image.
Hint: can contain a single TextureProperties node.
Hint: insert Shape and Appearance nodes before adding texture.
Warning: bright Material emissiveColor values can wash out some textures.
Hint: authors can provide multiple image formats for the same image, with each source
address listed separately in the url field.
Hint: player support is required for .png and .jpg formats, support is suggested for .gif
format. Other image formats are optionally supported.

[attrib accessType inputOutput, type MFNode array, empty list] [X3DVertexAttributeNode]
Single contained FloatVertexAttribute node that can specify list of per-vertex attribute
information for programmable shaders.
Hint: X3D Architecture 32.2.2.4 Per-vertex attributes, https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/components/shaders.html#Pervertexattributes |
| color |
[color accessType inputOutput, type SFNode singleton, NULL node] [X3DColorNode]
Single contained Color or ColorRGBA node that can specify color values applied to
corresponding vertices according to colorIndex and colorPerVertex fields. |
| coord |
[coord accessType inputOutput, type SFNode singleton, NULL node] [X3DCoordinateNode]
Single contained Coordinate or CoordinateDouble node that can specify a list of
vertex values. |
| fogCoord |
[fogCoord accessType inputOutput, type SFNode singleton, NULL node] [FogCoordinate]
Single contained FogCoordinate node that can specify depth parameters for fog in
corresponding geometry. |
| normal |
[normal accessType inputOutput, type SFNode singleton, NULL node] [X3DNormalNode]
Single contained Normal node that can specify perpendicular vectors for corresponding
vertices to support rendering computations, applied according to the normalPerVertex
field.
Hint: useful for special effects. Normal vector computation by 3D graphics hardware is
quite fast so adding normals to a scene is typically unnecessary.
Warning: normal vectors increase file size, typically doubling geometry definitions. Normal
vectors are rapidly computed at run time by GPUs and thus are rarely needed in model
files if no special effects are expected. Normal vectors are rapidly computed at run
time by GPUs and thus are rarely needed in model files if no special effects are expected.
|
| texCoord |
[texCoord accessType inputOutput, type SFNode singleton, NULL node] [X3DTextureCoordinateNode]
Single contained TextureCoordinate, TextureCoordinateGenerator or MultiTextureCoordinate
node that can specify coordinates for texture mapping onto corresponding geometry.
|
| DEF |
[DEF type ID #IMPLIED]
DEF defines a unique ID name for this node, referenceable by other nodes.
Hint: descriptive DEF names improve clarity and help document a model.
Hint: well-defined names can simplify design and debugging through improved author understanding.
Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions |
| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| coordIndex |
[coordIndex accessType initializeOnly, type MFInt32 CDATA #IMPLIED] [-1,+β)
coordIndex indices provide the order in which coordinates are applied to construct
each polygon face. Order starts at index 0, commas are optional between sets.
Hint: sentinel value -1 is used to separate indices for each successive polygon.
Warning: coordIndex is required in order to connect contained coordinate point values. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| convex |
[convex accessType initializeOnly, type SFBool (true|false) "true"]
The convex field is a hint to renderers whether all polygons in a shape are convex
(true), or possibly concave (false). A convex polygon is planar, does not intersect
itself, and has all interior angles < 180 degrees.
Hint: concave is the opposite of convex. Interchange profile
Hint: only convex=true IndexedFaceSets have guaranteed support.
Warning: concave or inverted geometry may be invisible when using default value convex=true,
since some renderers use more-efficient algorithms to perform tessellation that may
inadvertently fail on concave geometry.
Hint: select convex=false (i.e. concave) and solid=false (i.e. two-sided display) for
greatest visibility of geometry.
Hint: convex polygon https://en.wikipedia.org/wiki/Convex_polygon
Hint: tessellation https://en.wikipedia.org/wiki/Tessellation |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.
|
| creaseAngle |
[creaseAngle accessType initializeOnly, type SFFloat CDATA "0"] [0,+β)
creaseAngle defines angle (in radians) for determining whether adjacent polygons
are drawn with sharp edges or smooth shading. If angle between normals of two adjacent
polygons is less than creaseAngle, smooth shading is rendered across the shared line
segment. Interchange profile
Hint: only 0 and Ο radians supported.
Hint: creaseAngle=0 means render all edges sharply, creaseAngle=3.14159 means render all
edges smoothly.
Hint: radian units for angular measure https://en.wikipedia.org/wiki/Radian |
| colorPerVertex |
[colorPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Color|ColorRGBA values are applied to each point vertex (true) or to each
polygon face (false).
Warning: if child Color|ColorRGBA node is not provided, then geometry is rendered using corresponding
Appearance and material/texture values.
Hint: X3D Scene Authoring Hints, Color https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Color |

[colorIndex accessType initializeOnly, type MFInt32 CDATA #IMPLIED] [-1,+β)
colorIndex values define the order in which Color|ColorRGBA values are applied to
polygons (or vertices), interspersed by -1 if colorlPerVertex=true.
Hint: if colorIndex array is not provided, then Color|ColorRGBA values are indexed according
to the coordIndex field. Omitting duplicative colorIndex fields can reduce file size.
Hint: If colorPerVertex='false' then one index is provided for each polygon defined by
the coordIndex array. No sentinel -1 values are included.
Hint: If colorPerVertex='true' then a matching set of indices is provided, each separated
by sentinel -1, that exactly corresponds to individual values in the coordIndex array
polygon definitions.
Warning: if child Color|ColorRGBA node is not provided, then geometry is rendered using corresponding
Appearance and material/texture values. |
| normalPerVertex |
[normalPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Normal node vector values are applied to each point vertex (true) or to
each polygon face (false).
Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices. |
| normalIndex |
[normalIndex accessType initializeOnly, type MFInt32 CDATA #IMPLIED] [-1,+β)
normalIndex values define the order in which normal vectors are applied to polygons
(or vertices), interspersed by -1 if normalPerVertex=true.
Hint: if normalIndex array is not provided, then Normal values are indexed according to
the coordIndex field. Omitting duplicative normalIndex fields can reduce file size.
Hint: If normalPerVertex='false' then one index is provided for each polygon defined by
the coordIndex array. No sentinel -1 values are included.
Hint: If normalPerVertex='true' then a matching set of indices is provided, each separated
by sentinel -1, that exactly corresponds to individual values in the coordIndex array
polygon definitions.
Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices. Interchange
profile
Hint: this field may be ignored, applying the default value regardless. |
| texCoordIndex |
[texCoordIndex accessType initializeOnly, type MFInt32 CDATA #IMPLIED] [-1,+β)
List of texture-coordinate indices mapping attached texture to corresponding coordinates.
Hint: if texCoordIndex array is not provided, then TextureCoordinate values are indexed
according to the coordIndex field. Omitting duplicative texCoordIndex fields can reduce
file size.
Hint: use an authoring tool! |
| set_colorIndex |
[set_colorIndex accessType inputOnly, type MFInt32 CDATA #FIXED ""]
colorIndex values define the order in which Color|ColorRGBA values are applied to
polygons (or vertices), interspersed by -1 if colorlPerVertex=true.
Hint: if colorIndex array is not provided, then Color|ColorRGBA values are indexed according
to the coordIndex field. Omitting duplicative colorIndex fields can reduce file size.
Hint: If colorPerVertex='false' then one index is provided for each polygon defined by
the coordIndex array. No sentinel -1 values are included.
Hint: If colorPerVertex='true' then a matching set of indices is provided, each separated
by sentinel -1, that exactly corresponds to individual values in the coordIndex array
polygon definitions.
Warning: it is an error to define this transient inputOnly field in an X3D file, instead
only use it a destination for ROUTE events.
Hint: this field is not accessType inputOutput since X3D browsers might use different
underlying geometric representations for high-performance rendering, and so output
events are not appropriate. |
| set_coordIndex |
[set_coordIndex accessType inputOnly, type MFInt32 CDATA #FIXED ""]
coordIndex indices provide the order in which coordinates are applied to construct
each polygon face. Order starts at index 0, commas are optional between sets.

| containerField |
[containerField type NMTOKEN "geometry"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds

IndexedLineSet |
[inherits X3DGeometryNode]
IndexedLineSet defines polyline segments using index lists corresponding to vertex
coordinates. IndexedLineSet is a geometry node that can contain a Coordinate|CoordinateDouble
node and optionally a Color|ColorRGBA node.
Hint: Polygonal chain https://en.wikipedia.org/wiki/Polygonal_chain
Hint: either values in a contained Color node, or else Material emissiveColor in corresponding
Appearance node, are used for rendering lines and points.
Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection.
Warning: use a different color (or Material emissiveColor) than the Background color, otherwise
geometry is invisible.
Hint: adding LineProperties to the corresponding Appearance node can modify the rendering
style of these lines.
Hint: if rendering Coordinate points originally defined for an IndexedFaceSet,
index values may need to repeat each initial vertex to close each polygon outline.
Hint: step-wise variation or linear interpolation of color values can be used as a good
scientific visualization technique to map arbitrary function values to a color map.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: for advanced extensibility, authors can substitute a type-matched ProtoInstance
node (with correct containerField value) for contained node content.
Hint: consider including Fog (with Fog color matching Background color) to provide further
depth cueing for IndexedLineSet (ILS). |

Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions |
| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| index |
[index accessType initializeOnly, type MFInt32 CDATA #IMPLIED] [0,+β)
index values provide order in which coordinates are applied. Order starts at index
0, commas are optional between sets. Four unique indices are defined for each quadrilateral.
Warning: -1 sentinel values are not allowed. |
| set_index |
[set_index accessType inputOnly, type MFInt32 CDATA #IMPLIED] [0,+β)
index values provide order in which coordinates are applied. Order starts at index
0, commas are optional between sets. Four unique indices are defined for each quadrilateral.
Warning: -1 sentinel values are not allowed.
Hint: this field is not accessType inputOutput since X3D browsers might use different
underlying geometric representations for high-performance rendering, and so output
events are not appropriate. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| colorPerVertex |
[colorPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Color|ColorRGBA values are applied to each point vertex (true) or to each
polygon face (false).
Warning: the provided value of IndexedQuadSet colorPerVertex field is ignored and always
treated as true.
Warning: if child Color|ColorRGBA node is not provided, then geometry is rendered using corresponding
Appearance and material/texture values.

| normalPerVertex |
[normalPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Normal node vector values are applied to each point vertex (true) or to
each polygon face (false).
Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices. |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.
|
| containerField |
[containerField type NMTOKEN "geometry"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| index |
[index accessType initializeOnly, type MFInt32 CDATA #IMPLIED] [-1,+β)
index list specifies triangles by connecting Coordinate vertices for each individual
strip, separated by -1 sentinel values. |
| set_index |
[set_index accessType inputOnly, type MFInt32 CDATA #IMPLIED] [-1,+β)
index list specifies triangles by connecting Coordinate vertices for each individual
strip, separated by -1 sentinel values.
Hint: this field is not accessType inputOutput since X3D browsers might use different
underlying geometric representations for high-performance rendering, and so output
events are not appropriate. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| colorPerVertex |
[colorPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Color|ColorRGBA values are applied to each point vertex (true) or to each
polygon face (false).
Warning: the provided value of IndexedTriangleStripSet colorPerVertex field is ignored and
always treated as true.
Warning: if child Color|ColorRGBA node is not provided, then geometry is rendered using corresponding
Appearance and material/texture values.
Hint: X3D Scene Authoring Hints, Color https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Color |
| normalPerVertex |
[normalPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Normal node vector values are applied to each point vertex (true) or to
each polygon face (false).
Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices. |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.
|
| containerField |
[containerField type NMTOKEN "geometry"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

Hint: if preceding file loading fails or load field is false, no refresh is performed.
Hint: repeated refresh attempts to reload currently loaded entry of url list. If that
fails, the browser retries other entries in the url list.
Warning: automatically reloading content has security considerations and needs to be considered
carefully. |
| autoRefreshTimeLimit |
[autoRefreshTimeLimit accessType inputOutput, type SFTime CDATA "3600.0"]
autoRefreshTimeLimit defines maximum duration that automatic refresh activity can
occur.
Hint: Automatic refresh is different than query and response timeouts performed by a networking
library while sequentially attempting to retrieve addressed content from a url list.
Warning: automatically reloading content has security considerations and needs to be considered
carefully. |
| description |
[description accessType inputOutput, type SFString CDATA #IMPLIED]
Author-provided prose that describes intended purpose of the url asset.
Hint: many XML tools substitute XML character references for special characters automatically

| global |
[global accessType inputOutput, type SFBool (true|false) "false"]
The global field controls potential external scoping effects of lights found within

Hint: MFString arrays can have multiple values, so separate each individual string by
quote marks "https://www.web3d.org" "https://www.web3d.org/about" "etc."
Hint: alternative XML encoding for quotation mark " is " (which is an example of
a character entity).
Warning: strictly match directory and filename capitalization for http links! This is important
for portability. Some operating systems are forgiving of capitalization mismatches,
but http/https url addresses and paths in Unix-based operating systems are all case
sensitive and intolerant of uppercase/lowercase mismatches.
Hint: can replace embedded blank(s) in url queries with %20 for each blank character.

| bboxCenter |
[bboxCenter accessType initializeOnly, type SFVec3f CDATA "0 0 0"]
Bounding box center accompanies bboxSize and provides an optional hint for bounding
box position offset from origin of local coordinate system.
Hint: precomputation and inclusion of bounding box information can speed up the initialization
of large detailed models, with a corresponding cost of increased file size.

| bboxSize |
[bboxSize accessType initializeOnly, type SFVec3f CDATA "-1 -1 -1"] or [0,+β)
Bounding box size is usually omitted, and can easily be calculated automatically
by an X3D player at scene-loading time with minimal computational cost. Bounding box
size can also be defined as an optional authoring hint that suggests an optimization
or constraint.
Hint: can be useful for collision computations or inverse-kinematics (IK) engines.

IsoSurfaceVolumeData |
(X3D version 3.3 or later) [inherits X3DVolumeDataNode]
IsoSurfaceVolumeData displays one or more surfaces extracted from a voxel dataset.
A surface is defined as the boundary between regions in the volume where the voxel
values are larger than a given value (the iso value) on one side of the boundary and
smaller on the other side, and the gradient magnitude is larger than surfaceTolerance.
Hint: IsoSurfaceVolumeData can contain a single Texture3D node with containerField='gradients'
that is used to provide explicit per-voxel gradient direction information for determining
surface boundaries, rather than having values implicitly calculated by the implementation.
Hint: IsoSurfaceVolumeData can contain another Texture3D node with containerField='voxels'
containing voxel data.
Hint: IsoSurfaceVolumeData can contain multiple VolumeStyle nodes.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead
only use it a source for ROUTE events.
Warning: requires X3D profile='Full' or else include <component name='VolumeRendering' level='2'/>

| viewport |
[viewport accessType inputOutput, type SFNode singleton, NULL node] [X3DViewportNode]
The viewport field is a single Viewport node that constrains layer output to a sub-region
of the render surface. |
| objectType |
[objectType accessType inputOutput, type MFString CDATA ( ALL|NONE|TERRAIN|... ) "ALL"]
The objectType field specifies a set of labels used in the picking process. Each
string specified is treated as an independent label that needs to be matched against
the same type in one of the pick sensor instances.
Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to
intersect a pick sensor with objectType value "GROUND" fails since the objectType
values do not match.
Example: the special value "ALL" means that each node is available for picking regardless
of the type specified by the pick sensor.
Example: the special value "NONE" effectively disables all picking for this node and is the
equivalent of setting the pickable field to false.
Hint: authors may define any value for objectType.
Hint: MFString arrays can have multiple values, so "separate each individual string" "by
using quote marks". |
| pickable |
[pickable accessType inputOutput, type SFBool (true|false) "true"]
pickable determines whether pick traversal is performed for this layer. |
| visible |
[visible accessType inputOutput, type SFBool (true|false) "true"]
Whether or not renderable content within this node is visually displayed.
Hint: the visible field has no effect on animation behaviors, event passing or other non-visual
characteristics.
Hint: content must be visible to be collidable and to be pickable. |
| containerField |
[containerField type NMTOKEN "children"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

| align |
[align accessType inputOutput, type MFString CDATA ( LEFT|CENTER|RIGHT ) ( BOTTOM|CENTER|TOP ) "CENTER" "CENTER"]
The align field values align the sized rectangle to an edge or center of the parent
rectangle. Two quoted string values are provided. The first value is for horizontal
direction (LEFT|CENTER|RIGHT) and the second value is for vertical direction (BOTTOM|CENTER|TOP).
Examples: "CENTER" "CENTER" (default value), "LEFT" "TOP" or "RIGHT" "BOTTOM".
Warning: two values (or possibly one value) only.
Warning: if the align field has only one value, that value shall be "CENTER" and apply both
horizontally and vertically.
Hint: MFString arrays can have multiple values, so "separate each individual string" "by
using quote marks". |
| offset |
[offset accessType initializeOnly, type MFFloat CDATA 0 0] (-β,+β)
The values of the offset field are used to translate the location of this rectangle
after the initial alignment. The offsetUnits field specifies how to interpret the
offset field.
Warning: if only one value is provided, it applies equally to horizontal and vertical directions
(width and height). More than two values are not allowed. |
| offsetUnits |
[offsetUnits accessType inputOutput, type MFString CDATA ( WORLD|FRACTION|PIXEL ) "WORLD" "WORLD"]

value is for vertical scale.
Examples: "NONE" "NONE" (default value), "FRACTION" "FRACTION", "STRETCH" "STRETCH" or "PIXEL"
"PIXEL".
Hint: A scaleMode field value of NONE specifies that the corresponding scale value is
not modified. Instead, the scale is inherited from its parent. Since a LayoutLayer
node does not have a parent, the value of NONE reverts to FRACTION.
Hint: A scaleMode value of FRACTION specifies a scale in the corresponding direction so
that one unit is equal to the dimension (width or height) of this rectangle.
Hint: a scaleMode value of STRETCH specifies a scale in the corresponding direction such
that the resulting scale in the horizontal direction is equal to the scale in the
vertical direction, thus producing a uniform scale.
Hint: a value of PIXEL specifies a scale in the corresponding direction such that one
unit is equal to one pixel.

LayoutGroup |
(X3D version 3.2 or later) [inherits X3DGroupingNode, implements X3DVisibleObject]
LayoutGroup is a Grouping node that can contain most nodes, whose children are related
by a common layout within a parent layout.
The layout field contains an X3DLayoutNode node that provides the information required
to locate and size the layout region of the LayoutGroup node relative to its parentβs
layout region. LayoutGroup content is clipped by the specified viewport node.
Hint: The origin of the node is always in the center of its layout region. Thus, children
(with the exception of LayoutGroup) are specified in a coordinate system whose origin
is located at the center of the rectangle and can be transformed from that location.
Warning: a LayoutGroup can only be a child of a LayoutLayer node or another LayoutGroup node.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: LayoutGroup does not directly have any pixel-dependent concepts. However, it can
contain a Layout node that does have pixel-specific options. |

the same type in one of the pick sensor instances.
Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to
intersect a pick sensor with objectType value "GROUND" fails since the objectType
values do not match.
Example: the special value "ALL" means that each node is available for picking regardless
of the type specified by the pick sensor.
Example: the special value "NONE" effectively disables all picking for this node and is the
equivalent of setting the pickable field to false.

LinePickSensor |
(X3D version 3.2 or later) [inherits X3DPickSensorNode]
LinePickSensor uses one or more pickingGeometry line segments to compute intersections
with pickTarget shapes. As each line intersection generates a known point in space,
useful event information is returned including normal, geometry and texCoord values.
Hint: sort order for line picking is based on each pair of coordinates that defining a
line segment, with first declared vertex of the segment defined to be the start of
the line to which the intersection points are closest.
Hint: when the picking line segment intersects a coplanar polygon, computed intersection
point(s) are illustrated in Figure 38.1 https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/components/picking.html#f-LineIntersection
Hint: picking is performed between rendered frames of the event model. An author sets
up the picking request in one frame by placing a LinePickSensor in the desired location.
At the start of the next frame, any picking intersections are reported by the pick
sensor.
Hint: picking notification is performed at the start of the frame for all enabled pick
sensors once all other sensors are processed.
Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model
https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/concepts.html#ExecutionModel

LineSet |
[inherits X3DGeometryNode]
LineSet is a geometry node that can contain a Coordinate|CoordinateDouble node and
optionally a Color|ColorRGBA node.
Hint: Polygonal chain https://en.wikipedia.org/wiki/Polygonal_chain
Hint: either values in a contained Color node, or else Material emissiveColor in corresponding
Appearance node, are used for rendering lines and points.
Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection.
Warning: use a different color (or Material emissiveColor) than the Background color, otherwise
geometry is invisible.
Hint: adding LineProperties to the corresponding Appearance node can modify the rendering
style of these lines.
Hint: step-wise variation or linear interpolation of color values can be used as a good
scientific visualization technique to map arbitrary function values to a color map.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: for advanced extensibility, authors can substitute a type-matched ProtoInstance
node (with correct containerField value) for contained node content.
Hint: consider including Fog (with Fog color matching Background color) to provide further
depth cueing for LineSet (LS). |

LOD |
[inherits X3DGroupingNode, implements X3DVisibleObject]
LOD (Level Of Detail) uses camera-to-object distance to switch among contained child
levels.
(Contained nodes are now called 'children' rather than 'level',
for consistent naming among all GroupingNodeType nodes.)
LOD range values go from near to far (as child geometry gets simpler for better performance).
For n range values, you must have n+1 children levels!
Only currently selected children level is rendered, but all levels continue to send/receive
events.
Hint: can add <WorldInfo info='null node'/> as a nonrendering, invisible final (or initial
or intermediate) child node that also documents the LOD switch-over rationale.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: GeoViewpoint OrthoViewpoint and Viewpoint share the same binding stack, so no more
than one of these nodes can be bound and active at a given time.
Warning: do not include GeoViewpoint OrthoViewpoint or Viewpoint as a child of LOD or Switch,
instead use ViewpointGroup as parent to constrain location proximity where the viewpoint
is available to user.
Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint,
TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
Avoid this authoring pattern.
Hint: security mechanisms such as encryption and authentication can be applied to high
levels of detail, allowing authors to protect intellectual property at high resolution
for authorized users while still rendering simple unrestricted models for other users.
Warning: nested LOD (and/or GeoLOD) nodes with overlapping range intervals can lead to unexpected
or undefined behavior.
Hint: contained nodes must have type X3DChildNode, such as Group or Transform or Shape.
Warning: LOD is not allowed as a direct parent of Appearance, Material, Color, Coordinate,
Normal or Texture nodes, instead ensure that a Shape is present.
Hint: apply containerField='shape' if parent node is CADFace.

| children |
[children accessType inputOutput, type MFNode array, empty list] [X3DChildNode]
Grouping nodes contain an ordered list of children nodes.
Hint: Each grouping node defines a coordinate space for its children, relative to the
coordinate space of its parent node. Thus transformations accumulate down the scene
graph hierarchy.
Hint: inputOnly MFNode addChildren field can append new X3DChildNode nodes via a ROUTE
connection, duplicate input nodes (i.e. matching DEF, USE values) are ignored.
Hint: inputOnly MFNode removeChildren field can remove nodes from the children list, unrecognized
input nodes (i.e. nonmatching DEF, USE values) are ignored.

| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| forceTransitions |
[forceTransitions accessType initializeOnly, type SFBool (true|false) "false"]

Viewpoint distance-measurement offset from origin of local coordinate system, used
for LOD node distance calculations. |
| range |
[range accessType initializeOnly, type MFFloat CDATA #IMPLIED] (0,+β)
Specifies ideal distances at which to switch between levels. The range field is
a floating-point array of camera-to-object distance transitions for each child level,
where range values go from near to far. For n range values, you must have n+1 child
levels!
Hint: can add <WorldInfo info='null node'/> as a nonrendering, invisible final (or initial
or intermediate) child node that also documents the LOD switch-over rationale.
Hint: not setting range values indicates that level switching can be optimized automatically
based on performance. |
| bboxCenter |
[bboxCenter accessType initializeOnly, type SFVec3f CDATA "0 0 0"]
Bounding box center accompanies bboxSize and provides an optional hint for bounding
box position offset from origin of local coordinate system.
Hint: precomputation and inclusion of bounding box information can speed up the initialization
of large detailed models, with a corresponding cost of increased file size.

| bboxSize |
[bboxSize accessType initializeOnly, type SFVec3f CDATA "-1 -1 -1"] or [0,+β)
Bounding box size is usually omitted, and can easily be calculated automatically
by an X3D player at scene-loading time with minimal computational cost. Bounding box
size can also be defined as an optional authoring hint that suggests an optimization
or constraint.
Hint: can be useful for collision computations or inverse-kinematics (IK) engines.

Hint: content must be visible to be collidable and to be pickable. |
| level_changed |
[level_changed accessType outputOnly, type SFInt32 CDATA #FIXED ""]
Output event that reports current level of LOD children whenever switching occurs.
Hint: LOD level index counting starts at zero. Thus level_changed value of -1 means no
choice, 0 means initial child, 1 means second child, etc.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead
only use it a source for ROUTE events. |

| DEF |
[DEF type ID #IMPLIED]
DEF defines a unique ID name for this node, referenceable by other nodes.
Hint: descriptive DEF names improve clarity and help document a model.
Hint: well-defined names can simplify design and debugging through improved author understanding.
Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions |
| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |

| value |
[value accessType inputOutput, type MFMatrix3f CDATA ""]
value specifies an arbitrary collection of matrix values that will be passed to
the shader as per-vertex information.
Hint: the length of the value field shall be a multiple of numComponents. |
| containerField |
[containerField type NMTOKEN "attrib"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

MetadataBoolean |
(X3D version 3.3 or later) [inherits X3DNode, implements X3DMetadataObject]
MetadataBoolean contains a typed list of values providing metadata information about
its parent node.
Further information about this specific Metadata* node may be provided by a single
child Metadata* node with containerField="metadata".
Hint: typically use containerField="value" if the parent node is MetadataSet.
Warning: default containerField="metadata" in X3D 3 changed to default containerField="value"
in X3D 4.0, allowing construction of much terser MetadataSet vocabulary structures.
Hint: explicitly defining containerField for Metadata nodes is always allowed and also
unambiguous across each version of X3D.
Hint: each of the Metadata nodes are allowed as top-level root nodes in a scene, if doing
that be sure to explicitly define containerField='metadata'. https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/concepts.html#Rootnodes
Warning: Metadata nodes can only contain other Metadata nodes.
Hint: if present, an IS statement is the first child within any other node.
Hint: an IS statement precedes any sibling Metadata* node, which in turn precedes any
other sibling nodes.
Hint: comments are not readable when a model file is loaded for viewing, but WorldInfo

Hint: default containerField values for each node are correct in most cases, so the need

MetadataFloat |
[inherits X3DNode, implements X3DMetadataObject]
MetadataFloat contains a typed list of values providing metadata information about
its parent node.
Further information about this specific Metadata* node may be provided by a single
child Metadata* node with containerField="metadata".
Hint: typically use containerField="value" if the parent node is MetadataSet.
Warning: default containerField="metadata" in X3D 3 changed to default containerField="value"
in X3D 4.0, allowing construction of much terser MetadataSet vocabulary structures.
Hint: explicitly defining containerField for Metadata nodes is always allowed and also
unambiguous across each version of X3D.
Hint: each of the Metadata nodes are allowed as top-level root nodes in a scene, if doing
that be sure to explicitly define containerField='metadata'. https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/concepts.html#Rootnodes
Warning: Metadata nodes can only contain other Metadata nodes.
Hint: if present, an IS statement is the first child within any other node.
Hint: an IS statement precedes any sibling Metadata* node, which in turn precedes any
other sibling nodes.
Hint: The choice of MetadataDouble versus MetadataFloat usually depends on the relevant
tool utilizing the value, or else the relevant metadata reference defining the value.
Hint: comments are not readable when a model file is loaded for viewing, but WorldInfo
and Metadata* nodes are persistent and inspectable at run time.

MovieTexture applies a 2D movie image to surface geometry, or provides audio for
a Sound node.
First define as texture, then USE as Sound source to see it/hear it/save memory.
Texture maps have a 2D coordinate system (s, t) horizontal and vertical, with (s,
t) texture-coordinate values in range [0.0, 1.0] for opposite corners of the image.
Hint: can contain a single TextureProperties node.
Hint: insert Shape and Appearance nodes before adding texture.
Hint: provide a Viewpoint that allows a clear view of the MovieTexture so that users can
easily see all details.
Hint: utilize DEF/USE references for multiple copies of a single MovieTexture video file
in order to avoid multiple-download delays, reduce memory requirements, and maintain
synchronization.
Hint: authors can provide multiple video formats for the same video track, with each source
address listed separately in the url field.
Hint: player support for MPEG-1 video format is required, other formats are optional.
Warning: MovieTexture has containerField='texture' when parent is an Appearance node, otherwise
containerField='source' when parent is a Sound node.
Hint: Texture coordinates are reapplied (or else recomputed if textureTransform field
initially NULL) whenever the corresponding vertex-based geometry changes.

MultiTexture |
[inherits X3DTextureNode]
MultiTexture applies several individual textures to a single geometry node, enabling
a variety of visual effects that include light mapping and environment mapping. MultiTexture
can contain zero or more ImageTexture, MovieTexture, PixelTexture, ComposedCubeMapTexture,
GeneratedCubeMapTexture, ImageCubeMapTexture, ComposedTexture3D, ImageTexture3D, and
PixelTexture3D nodes.
Texture maps have a 2D coordinate system (s, t) horizontal and vertical, with (s,
t) texture-coordinate values in range [0.0, 1.0] for opposite corners of the image.
Hint: insert Shape and Appearance nodes before adding texture.
Hint: Texture mapping https://en.wikipedia.org/wiki/Texture_mapping
Warning: the number of textures to be blended may have a significant impact on performance,
depending on available graphics hardware capabilities.
Hint: multitexturing is accomplished using MultiTexture, MultiTextureCoordinate and MultiTextureTransform
nodes.
Hint: Texture coordinates are reapplied (or else recomputed if textureTransform field
initially NULL) whenever the corresponding vertex-based geometry changes.

NavigationInfo |
[inherits X3DBindableNode]
NavigationInfo describes the user's viewing model, user navigation-interaction modalities,
and also dimensional characteristics of the user's (typically invisible) avatar.
Hint: for inspection of simple objects, usability often improves with type="EXAMINE" "ANY"
Hint: Background, Fog, GeoViewpoint, NavigationInfo, OrthoViewpoint, TextureBackground
and Viewpoint are bindable nodes, meaning that no more than one of each node type
can be active at a given time.
Hint: NavigationInfo types '"WALK" "FLY"' support camera-to-object collision detection.
Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint,
TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
Avoid this authoring pattern.
Hint: Regardless of viewpoint jump value at bind time, the relative viewing transformation
between user's view and defined position/orientation is stored for later use when
un-jumping (returning to the viewpoint when subsequent viewpoint is unbound).
Hint: customizable design pattern for dedicated Viewpoint/NavigationInfo pair: <Viewpoint

Normal |
[inherits X3DNormalNode]
Normal defines a set of 3D surface-normal vectors that apply either to a sibling
Coordinate|CoordinateDouble node, or else to a parent ElevationGrid node.
Normal values are perpendicular directions that are used per-polygon or per-vertex
when computing lighting and shading.
Hint: Normal values are typically only calculated or applied once, during initial loading
of model geometry.
Hint: custom Normal values can produce special effects.
Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices.
Hint: computation of normal values is performed quite quickly on modern 3D graphics hardware,
often with no perceptible delay.
Warning: adding normal values to a model might significantly increase file size. Testing
can help determine proper tradeoffs between file size, network transmission delays
and initial rendering speed.
Hint: normal vectors perpendicular to 3D surface https://en.wikipedia.org/wiki/Normal_(geometry) |

| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.

to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds

OrthoViewpoint provides an orthographic perspective-free view of a scene from a
specific location and direction.
Hint: Background, Fog, GeoViewpoint, NavigationInfo, OrthoViewpoint, TextureBackground
and Viewpoint are bindable nodes, meaning that no more than one of each node type
can be active at a given time.
Hint: GeoViewpoint OrthoViewpoint and Viewpoint share the same binding stack, so no more
than one of these nodes can be bound and active at a given time.
Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint,
TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
Avoid this authoring pattern.
Warning: do not include GeoViewpoint OrthoViewpoint or Viewpoint as a child of LOD or Switch,
instead use ViewpointGroup as parent to constrain location proximity where the viewpoint
is available to user.
Hint: Regardless of viewpoint jump value at bind time, the relative viewing transformation
between user's view and defined position/orientation is stored for later use when
un-jumping (returning to the viewpoint when subsequent viewpoint is unbound).
Hint: customizable design pattern for dedicated Viewpoint/NavigationInfo pair: <Viewpoint
DEF='SpecialView'/> <NavigationInfo DEF='SpecialNav'/> <ROUTE fromNode='SpecialView'
fromField='isBound' toNode='SpecialNav' toField='set_bind'/>

The navigationInfo field defines a dedicated NavigationInfo node for this X3DViewpointNode.
The specified NavigationInfo node receives a set_bind TRUE event at the time when
the parent node is bound and receives a set_bind FALSE at the time when the parent
node is unbound.
Hint: allows simple integration of custom navigation associated with each Viewpoint according
to user needs at that location. |
| viewAll |
[viewAll accessType inputOutput, type SFBool (true|false), false]
Viewpoint is automatically adjusted to view all visible geometry. Typically centerOfRotation
is shifted to center of current bounding box and view is zoomed in or out until all
visible objects are viewed.
Hint: no collision detection or proximity sensing occurs when zooming.
Warning: if needed, near and far clipping planes shall be adjusted to allow viewing the entire

Hint: the currently bound NavigationInfo node has a major effect on how a user might change
viewing position and orientation after reaching this Viewpoint.
Hint: consider paired Viewpoint/NavigationInfo node combinations by defining ROUTE connections
between corresponding isBound/set_bind fields.
Hint: include space characters since a description is not a DEF identifier. Write short
phrases that make descriptions clear and readable.
Warning: without description, this OrthoViewpoint is unlikely to appear on browser Viewpoint

Particle systems frequently like to change the texture on a particle as it ages, yet
there is no good way of accomplishing this through standard interpolators because
interpolators have no concept of particle time. This pair of fields hold time-dependent
values for the texture coordinates to be applied to the particle. When a particle
reaches the next time stamp it moves to the next set of texture coordinates.

the same type in one of the pick sensor instances.
Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to
intersect a pick sensor with objectType value "GROUND" fails since the objectType
values do not match.
Example: the special value "ALL" means that each node is available for picking regardless
of the type specified by the pick sensor.
Example: the special value "NONE" effectively disables all picking for this node and is the

PixelTexture |
[inherits X3DTexture2DNode]
PixelTexture creates a 2D-image texture map using a numeric array of pixel values.
Texture maps have a 2D coordinate system (s, t) horizontal and vertical, with (s,
t) texture-coordinate values in range [0.0, 1.0] for opposite corners of the image.
Hint: this is a good way to bundle image(s) into a single scene file, avoiding multiple
downloads.
Hint: X3D-Edit includes PixelTexture image-conversion import capabilities. https://savage.nps.edu/X3D-Edit/images/PixelTextureImportImage.png
Warning: aggregate file size can grow dramatically.
Hint: can contain a single TextureProperties node.
Hint: insert Shape and Appearance nodes before adding texture.
Hint: X3D Scene Authoring Hints, Images and Videos https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Images
Warning: see ComposedCubeMapTexture and TextureBackground for special containerField values.
Hint: if a texture is opaque, omitting values in the alpha channel can help avoid rendering
artifacts related to transparency.
Hint: Texture coordinates are reapplied (or else recomputed if textureTransform field
initially NULL) whenever the corresponding vertex-based geometry changes.

PointPickSensor |
(X3D version 3.2 or later) [inherits X3DPickSensorNode]
PointPickSensor tests one or more pickingGeometry points in space as lying inside
the provided pickTarget geometry. For each pickingGeometry PointSet coordinate point
that lies inside the pickTarget geometry, a pickedPoint coordinate is returned along
with a corresponding pickedGeometry node inside which the point lies.
Hint: because points represent an infinitely small location in space, sortOrder values
CLOSEST and ALL_SORTED are defined to mean ANY and ALL respectively.
Hint: picking is performed between rendered frames of the event model. An author sets
up the picking request in one frame by placing a LinePickSensor in the desired location.
At the start of the next frame, any picking intersections are reported by the pick
sensor.
Hint: picking notification is performed at the start of the frame for all enabled pick
sensors once all other sensors are processed.
Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model
https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/concepts.html#ExecutionModel
Warning: order of contained nodes is significant, single pickingGeometry node must precede
pickTarget node array.

| description |
[description accessType inputOutput, type SFString CDATA #IMPLIED]
Author-provided prose that describes intended purpose of the node.

| enabled |
[enabled accessType inputOutput, type SFBool (true|false) "true"]
Enables/disables node operation. |
| isActive |
[isActive accessType outputOnly, type SFBool #FIXED ""]
isActive indicates when the intersecting object is picked by the picking geometry.
Output event isActive=true gets sent once a picked item is found. Output event isActive=false
gets sent once no picked item is found.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead
only use it a source for ROUTE events. |
| intersectionType |
[intersectionType accessType initializeOnly, type SFString CDATA ( GEOMETRY|BOUNDS ) "BOUNDS"]
intersectionType specifies precision of the collision computation.
Hint: intersectionType constants may be extended by the browser to provide additional
options.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |
| matchCriterion |
[matchCriterion accessType inputOutput, type SFString CDATA ( MATCH_ANY|MATCH_EVERY|MATCH_ONLY_ONE ) "MATCH_ANY"]
defines whether the intersection test (i.e. pick) by this X3DPickSensorNode must
match one or more objectType. Specifically MATCH_ANY means any match of objectType
values is acceptable, MATCH_EVERY means that every objectType value in this node shall
match an objectType value in the X3DPickableObject, and MATCH_ONLY_ONE means that
one and only one objectType value can match. |
| objectType |
[objectType accessType inputOutput, type MFString CDATA ( ALL|NONE|TERRAIN|... ) "ALL"]
The objectType field specifies a set of labels used in the picking process. Each
string specified is treated as an independent label that needs to be matched against
the same type in one of the pick sensor instances.
Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to
intersect a pick sensor with objectType value "GROUND" fails since the objectType
values do not match.
Example: the special value "ALL" means that each node is available for picking regardless
of the type specified by the pick sensor.
Example: the special value "NONE" effectively disables all picking for this node and is the
equivalent of setting the pickable field of the corresponding PickableGroup to false.
Hint: authors may define any value for objectType.
Hint: MFString arrays can have multiple values, so "separate each individual string" "by
using quote marks". |
| sortOrder |
[sortOrder accessType initializeOnly, type SFString CDATA ( ANY|CLOSEST|ALL|ALL_SORTED|... ) "CLOSEST"]
The sortOrder field determines the order provided for picked output events.
Example: ANY means any single object that can satisfy picking conditions for this pick sensor.
Consistency of results is not guaranteed.
Example: ALL means that every object that satisfies the picking conditions for this pick
sensor shall be returned.
Example: ALL_SORTED means that every object that satisfies the picking conditions for this
pick sensor shall be returned with the order of the output fields provided in a distance-sorted
order from closest to farthest away. The exact algorithm for sorting is defined by
the individual node definitions.
Example: CLOSEST means that the closest object by distance that satisfies the conditions
of this pick sensor. *The exact algorithm for distance determination shall be defined
by individual node definitions*.
Hint: browser implementations may define additional values and algorithms beyond these
four required values.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |

PrimitivePickSensor |
(X3D version 3.2 or later) [inherits X3DPickSensorNode]
PrimitivePickSensor tests picking intersections using one of the basic primitive
shapes specified in the pickingGeometry field [Cone|Cylinder|Sphere|Box] against the
pickTarget geometry.
Warning: boolean fields used to control visibility of primitive pickingGeometry subsections
are ignored when evaluating picking intersections.
Example: a Cylinder without end caps is still treated as an enclosed Cylinder.
Hint: Sorting is defined based on the primitive type as follows. For Cone, the closest
picked primitive is defined to be that closest to the vertex point. For Cylinder,
Box, and Sphere, the closest picked primitive is defined to be that closest to the
center.
Hint: picking is performed between rendered frames of the event model. An author sets
up the picking request in one frame by placing a LinePickSensor in the desired location.
At the start of the next frame, any picking intersections are reported by the pick
sensor.
Hint: picking notification is performed at the start of the frame for all enabled pick
sensors once all other sensors are processed.
Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model
https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/concepts.html#ExecutionModel
Warning: order of contained nodes is significant, single pickingGeometry node must precede

pickTarget specifies the list of nodes against which picking operations are performed.
All nodes declared in this field and their descendents are evaluated for intersections.
|
| pickedGeometry |
[pickedGeometry accessType outputOnly, type MFNode #FIXED ""]
Output event containing the node or nodes that have been found to intersect with
the picking geometry from the last time this node performed a picking operation, given
in the local coordinate system.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead

| description |
[description accessType inputOutput, type SFString CDATA #IMPLIED]
Author-provided prose that describes intended purpose of the node.
Hint: many XML tools substitute XML character references for special characters automatically
if needed within an attribute value (such as & for & ampersand character, or "
for " quotation-mark character). |
| enabled |
[enabled accessType inputOutput, type SFBool (true|false) "true"]
Enables/disables node operation. |
| isActive |
[isActive accessType outputOnly, type SFBool #FIXED ""]
isActive indicates when the intersecting object is picked by the picking geometry.
Output event isActive=true gets sent once a picked item is found. Output event isActive=false
gets sent once no picked item is found.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead
only use it a source for ROUTE events. |
| intersectionType |
[intersectionType accessType initializeOnly, type SFString CDATA ( GEOMETRY|BOUNDS ) "BOUNDS"]
intersectionType specifies precision of the collision computation.
Hint: intersectionType constants may be extended by the browser to provide additional
options.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |
| matchCriterion |
[matchCriterion accessType inputOutput, type SFString CDATA ( MATCH_ANY|MATCH_EVERY|MATCH_ONLY_ONE ) "MATCH_ANY"]
defines whether the intersection test (i.e. pick) by this X3DPickSensorNode must
match one or more objectType. Specifically MATCH_ANY means any match of objectType
values is acceptable, MATCH_EVERY means that every objectType value in this node shall
match an objectType value in the X3DPickableObject, and MATCH_ONLY_ONE means that
one and only one objectType value can match. |
| objectType |
[objectType accessType inputOutput, type MFString CDATA ( ALL|NONE|TERRAIN|... ) "ALL"]
The objectType field specifies a set of labels used in the picking process. Each
string specified is treated as an independent label that needs to be matched against
the same type in one of the pick sensor instances.
Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to
intersect a pick sensor with objectType value "GROUND" fails since the objectType
values do not match.
Example: the special value "ALL" means that each node is available for picking regardless
of the type specified by the pick sensor.
Example: the special value "NONE" effectively disables all picking for this node and is the
equivalent of setting the pickable field of the corresponding PickableGroup to false.
Hint: authors may define any value for objectType.
Hint: MFString arrays can have multiple values, so "separate each individual string" "by
using quote marks". |
| sortOrder |
[sortOrder accessType initializeOnly, type SFString CDATA ( ANY|CLOSEST|ALL|ALL_SORTED|... ) "CLOSEST"]
The sortOrder field determines the order provided for picked output events.
Example: ANY means any single object that can satisfy picking conditions for this pick sensor.
Consistency of results is not guaranteed.
Example: ALL means that every object that satisfies the picking conditions for this pick
sensor shall be returned.
Example: ALL_SORTED means that every object that satisfies the picking conditions for this
pick sensor shall be returned with the order of the output fields provided in a distance-sorted
order from closest to farthest away. The exact algorithm for sorting is defined by
the individual node definitions.
Example: CLOSEST means that the closest object by distance that satisfies the conditions
of this pick sensor. *The exact algorithm for distance determination shall be defined
by individual node definitions*.
Hint: browser implementations may define additional values and algorithms beyond these
four required values.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |
| containerField |
[containerField type NMTOKEN "children"]

ProtoInstance |
[X3D statement]
ProtoInstance creates an instance node of a locally or externally declared prototype
definition. ProtoDeclare/ExternProtoDeclare definitions are abstract, corresponding
ProtoInstance nodes are concrete. ProtoInstance nodes typically contain fieldValue
statements to override default field values defined in the original ProtoDeclare statement.
Hint: the node type of a ProtoInstance exactly matches the first node in the corresponding
ProtoDeclare/ProtoBody declaration.
Warning: be sure to correctly set the containerField value to match the intended field in
the parent node.
Warning: do not mismatch node types when placing a ProtoInstance in a scene graph. Most validation
tools will not catch this error.
Hint: scene authors can override default initializations of prototype fields by including
contained <fieldValue> elements.
Hint: Nested ProtoInstance and ProtoDeclare statements are allowed within a ProtoDeclare/ProtoBody.
Hint: if contained within a ProtoDeclare, then a ProtoInstance node can also contain IS/connect
statements for other defined fields.
Warning: a ProtoInstance node may not be instantiated inside its own ProtoDeclare or ExternProtoDeclare
declaration (i.e. recursive prototypes are illegal).
Warning: the local context of each ProtoInstance node must match the node type of the first
node in the original ProtoDeclare declaration.
Warning: ProtoInstance substitution for a Metadata* node might not validate. Workaround:
put metadata-typed ProtoInstance nodes as contained values within a parent MetadataSet
node.

scene. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.

solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.

ROUTE |
[X3D statement]
ROUTE connects output fields of event-producing nodes to input fields of event-consuming
nodes.
Warning: each ROUTE must follow the DEF definition of both event-source and event-target
nodes.
Warning: strongly typed event checking means that data type (SFInt32, MFVec3f, etc.) must
match identically for both event-source and event-target fields.
Warning: event-source fields can have accessType outputOnly or inputOutput, while event-target
nodes can have accessType inputOnly or inputOutput.

Hint: Fan-in occurs when two or more routes have the same destination field. All events
are considered to have been received simultaneously; therefore, the order in which
they are processed is not considered relevant.
Hint: Fan-out occurs when one field is the source for more than one route. This results
in sending any event generated by the field along all routes. All events are considered
to have been sent simultaneously; therefore, the order in which they are processed
is not considered relevant.

Script |
[inherits X3DScriptNode]
Script contains author-programmed event behaviors for a scene.
Define the script input-output event interface by including <field/> elements.
Scripting code is embedded in a child CDATA node or (deprecated) in the url field.
Optionally supported programming languages are ECMAScript (JavaScript) and Java (via
url to a myNode.class file).
Hint: insert an XML Character Data (CDATA) block within the Script node to contain source
code embedded within an X3D scene, avoiding the need for escape characters.
Hint: a contained XML Character Data (CDATA) block for source code protects whitespace,
line breaks, and literal characters (such as & for ampersand character, < for less-than-sign
character, and > for greater-than-sign character) from unintended escape-character
modifications by XML parsers.
Warning: strict order is required for contained constructs: first field declarations (if
any), then IS/connect statements (if any), and finally CDATA source-code block.
Hint: X3D Scene Authoring Hints, Scripts https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Scripts

| autoRefresh |
[autoRefresh accessType inputOutput, type SFTime CDATA "0.0"]
autoRefresh defines interval in seconds before automatic reload of current url asset
is performed.
Hint: if preceding file loading fails or load field is false, no refresh is performed.
Hint: repeated refresh attempts to reload currently loaded entry of url list. If that
fails, the browser retries other entries in the url list.
Warning: automatically reloading content has security considerations and needs to be considered
carefully. |
| autoRefreshTimeLimit |
[autoRefreshTimeLimit accessType inputOutput, type SFTime CDATA "3600.0"]
autoRefreshTimeLimit defines maximum duration that automatic refresh activity can
occur.
Hint: Automatic refresh is different than query and response timeouts performed by a networking
library while sequentially attempting to retrieve addressed content from a url list.
Warning: automatically reloading content has security considerations and needs to be considered
carefully. |
| description |
[description accessType inputOutput, type SFString CDATA #IMPLIED]
Author-provided prose that describes intended purpose of the url asset.
Hint: many XML tools substitute XML character references for special characters automatically
if needed within an attribute value (such as & for & ampersand character, or "
for " quotation-mark character). |
| load |
[load accessType inputOutput, type SFBool (true|false) "true"]

or scripting.
Hint: use a separate LoadSensor node to detect when loading is complete. |
| url |
[url accessType inputOutput, type MFString CDATA #IMPLIED]
List of address links for runnable script files.
Hint: embedded ecmascript: source can also be contained in the sourceCode pseudo-field
without escape characters, equivalent to last entry in the url list, when using other

Hint: browsers are not required to support any particular scripting language, but ECMAScript
(JavaScript) is widely supported.
Hint: equivalent script code written in multiple programming languages can be provided
for portability, the first runnable version is chosen at run time.
Hint: X3D Scene Authoring Hints, Scripts https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Scripts
Warning: source code can be placed in url attribute but may be unparsable due to escaping
of special characters and elimination of line breaks (causing comments to nullify
follow-on code). Use contained CDATA section instead for embedding source code.
Hint: if both url field and CDATA section are provided simultaneously, the url field is
processed first. This approach allows utilization of update modifications or live
queries in external scripts, while still providing reliable script source as a fallback
alternative within the model itself.

Hint: alternative XML encoding for quotation mark " is " (which is an example of
a character entity).
Warning: strictly match directory and filename capitalization for http links! This is important
for portability. Some operating systems are forgiving of capitalization mismatches,
but http/https url addresses and paths in Unix-based operating systems are all case
sensitive and intolerant of uppercase/lowercase mismatches.

| directOutput |
[directOutput accessType initializeOnly, type SFBool (true|false) "false"]
Set directOutput true if Script has field reference(s) of type SFNode/MFNode, and
also uses direct access to modify attributes of a referenced node in the Scene.
Hint: set directOutput true if Script dynamically establishes or breaks ROUTEs.
Hint: directOutput is a browser hint to avoid overoptimizing referenced nodes, since a
Script might directly change attribute values in referenced SFNode/MFNode fields,
without a ROUTE connecting output events.
Hint: directOutput false means Script cannot modify referenced nodes or change ROUTEs.

| mustEvaluate |
[mustEvaluate accessType initializeOnly, type SFBool (true|false) "false"]
If mustEvaluate false, then the X3D player may delay sending input events to Script
until output events are needed. If mustEvaluate true, then Script must receive input
events immediately without any event-aggregation delays.
Hint: set mustEvaluate true when sending/receiving values via the network. |
| containerField |
[containerField type NMTOKEN (children|watchList) "children"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

ShaderPart |
(X3D version 3.1 or later) [inherits X3DNode, implements X3DUrlObject]
ShaderPart defines the source for a portion of source code used by a ComposedShader
node.
The source is not required to be a complete shader for all of the vertex/fragment
processing.
Hint: ShaderPart can contain a CDATA block of plain-text source code.
Hint: embedded ecmascript: source can also be contained in the sourceCode pseudo-field
without escape characters, equivalent to last entry in the url list, when using other
API codebases and file encodings.
Warning: ShaderPart contains no field declarations.
Hint: insert an XML Character Data (CDATA) block within the Script node to contain source
code embedded within an X3D scene, avoiding the need for escape characters.
Hint: a contained XML Character Data (CDATA) block for source code protects whitespace,
line breaks, and literal characters (such as & for ampersand character, < for less-than-sign
character, and > for greater-than-sign character) from unintended escape-character
modifications by XML parsers.
Warning: strict order is required for contained constructs: first field declarations (if
any), then IS/connect statements (if any), and finally CDATA source-code block.
Hint: ShaderPart subprograms are written in the same language, which is specified in the
parent ComposedShader node.
Hint: when parent node is LoadSensor, apply containerField='children' (X3Dv4) or containerField='watchList'
(X3Dv3). https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#fieldNameChanges |

ShaderProgram |
(X3D version 3.1 or later) [inherits X3DNode, implements X3DUrlObject, X3DProgrammableShaderObject]
ShaderProgram is contained by ProgramShader and provides the source and interface
to a self-contained program that occupies one part of the rendering process:
either a vertex or fragment shader.
Hint: ShaderProgram contains field declarations and then corresponding IS/connect statements
(if any).
Hint: insert an XML Character Data (CDATA) block within the Script node to contain source
code embedded within an X3D scene, avoiding the need for escape characters.
Hint: a contained XML Character Data (CDATA) block for source code protects whitespace,
line breaks, and literal characters (such as & for ampersand character, < for less-than-sign
character, and > for greater-than-sign character) from unintended escape-character
modifications by XML parsers.
Warning: strict order is required for contained constructs: first field declarations (if
any), then IS/connect statements (if any), and finally CDATA source-code block.
Hint: when parent node is LoadSensor, apply containerField='children' (X3Dv4) or containerField='watchList'
(X3Dv3). https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#fieldNameChanges
Hint: embedded ecmascript: source can also be contained in the sourceCode pseudo-field
without escape characters, equivalent to last entry in the url list, when using other
API codebases and file encodings. |

| DEF |
[DEF type ID #IMPLIED]
DEF defines a unique ID name for this node, referenceable by other nodes.
Hint: descriptive DEF names improve clarity and help document a model.
Hint: well-defined names can simplify design and debugging through improved author understanding.
Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions |
| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| autoRefresh |
[autoRefresh accessType inputOutput, type SFTime CDATA "0.0"]
autoRefresh defines interval in seconds before automatic reload of current url asset
is performed.
Hint: if preceding file loading fails or load field is false, no refresh is performed.
Hint: repeated refresh attempts to reload currently loaded entry of url list. If that
fails, the browser retries other entries in the url list.
Warning: automatically reloading content has security considerations and needs to be considered
carefully. |
| autoRefreshTimeLimit |
[autoRefreshTimeLimit accessType inputOutput, type SFTime CDATA "3600.0"]
autoRefreshTimeLimit defines maximum duration that automatic refresh activity can
occur.
Hint: Automatic refresh is different than query and response timeouts performed by a networking
library while sequentially attempting to retrieve addressed content from a url list.
Warning: automatically reloading content has security considerations and needs to be considered
carefully. |
| description |
[description accessType inputOutput, type SFString CDATA #IMPLIED]
Author-provided prose that describes intended purpose of the url asset.
Hint: many XML tools substitute XML character references for special characters automatically
if needed within an attribute value (such as & for & ampersand character, or "
for " quotation-mark character). |
| load |
[load accessType inputOutput, type SFBool (true|false) "true"]
load=true means load immediately, load=false means defer loading or else unload
a previously loaded scene.
Hint: allows author to design when Inline loading occurs via user interaction, event chains
or scripting.
Hint: use a separate LoadSensor node to detect when loading is complete. |
| url |
[url accessType inputOutput, type MFString CDATA #IMPLIED]
Location and filename of shader. Multiple locations are more reliable, and including
a Web address lets e-mail attachments work.
Hint: embedded ecmascript: source can also be contained in the sourceCode pseudo-field
without escape characters, equivalent to last entry in the url list, when using other
API codebases and file encodings.
Hint: MFString arrays can have multiple values, so separate each individual string by
quote marks "https://www.web3d.org" "https://www.web3d.org/about" "etc."
Hint: alternative XML encoding for quotation mark " is " (which is an example of
a character entity).
Warning: strictly match directory and filename capitalization for http links! This is important
for portability. Some operating systems are forgiving of capitalization mismatches,
but http/https url addresses and paths in Unix-based operating systems are all case
sensitive and intolerant of uppercase/lowercase mismatches.
Hint: can replace embedded blank(s) in url queries with %20 for each blank character.
Hint: X3D Scene Authoring Hints, urls https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#urls |
| type |
[type accessType initializeOnly, type SFString CDATA (VERTEX|FRAGMENT) VERTEX]
type indicates whether this ShaderProgram is a vertex or fragment (pixel) shader.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |
| containerField |
[containerField type NMTOKEN (programs|watchList) "programs"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

Shape |
[inherits X3DShapeNode, implements X3DVisibleObject]
Shape can appear under any grouping node.
Shape can contain an Appearance node and a geometry node (for example one of the primitives
Box Cone Cylinder Sphere Text, one of ElevationGrid Extrusion IndexedFaceSet IndexedLineSet
LineSet PointSet, or one of the other geometry nodes).
Hint: Shape https://en.wikipedia.org/wiki/Shape
Hint: the Shape design pattern to collect appearance and geometry together is fundamentally
the same for many types of 3D graphics software and hardware.
Hint: for advanced extensibility, authors can substitute a type-matched ProtoInstance
node (with correct containerField value) for contained node content.

Switch |
[inherits X3DGroupingNode, implements X3DVisibleObject]
Switch is a Grouping node that only renders one (or zero) child at a time.
Switch can contain most nodes.
(Contained nodes are now called 'children' rather than 'choice',
for consistent naming among all GroupingNodeType nodes.)
All child choices continue to receive and send events regardless of whichChoice is
active.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: authors can temporarily hide test geometry under an unselected child of a Switch.
This is a good alternative to "commenting out" nodes.
Hint: GeoViewpoint OrthoViewpoint and Viewpoint share the same binding stack, so no more
than one of these nodes can be bound and active at a given time.
Warning: do not include GeoViewpoint OrthoViewpoint or Viewpoint as a child of LOD or Switch,
instead use ViewpointGroup as parent to constrain location proximity where the viewpoint
is available to user.
Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint,
TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
Avoid this authoring pattern.
Hint: contained nodes must have type X3DChildNode, such as Group or Transform or Shape.
Warning: Switch is not allowed as parent of Appearance, Material, Color, Coordinate, Normal
or Texture nodes. |

Transform |
[inherits X3DGroupingNode, implements X3DVisibleObject]
Transform is a Grouping node that can contain most nodes. Transform translates,
orients and scales child geometry within the local world coordinate system.
Hint: each transformation creates a new coordinate system relative to the parent coordinate
system.
Hint: +Y axis is the up direction. (Similarly some scenes may consider +X is North and
+Z is East.)
Hint: best authoring approach is to keep +Y axis pointing towards local up direction,
supporting scene composability and effective navigation response (which is based on
gravity direction).
Hint: insert a Shape node before adding geometry or Appearance.
Hint: translation/rotation/scaling field attributes can be defined in any order in the
scene. The applied order of translation/rotation/scaling transformation-matrix operations
remains consistent.
Hint: authors can modify order of translation/rotation/scaling operations by splitting
them into separate nested parent/child Transform nodes.

Hint: Each grouping node defines a coordinate space for its children, relative to the
coordinate space of its parent node. Thus transformations accumulate down the scene
graph hierarchy.

connection, duplicate input nodes (i.e. matching DEF, USE values) are ignored.
Hint: inputOnly MFNode removeChildren field can remove nodes from the children list, unrecognized
input nodes (i.e. nonmatching DEF, USE values) are ignored.

TransformSensor |
(X3D version 3.2 or later) [inherits X3DEnvironmentalSensorNode]
TransformSensor generates output events when its targetObject enters, exits, and
moves within a region in space (defined by a box).
Hint: Each TransformSensor node behaves independently of all other TransformSensor nodes,
so that every enabled TransformSensor node affected by targetObject motion sends output
events.
Hint: multiply instanced (DEF/USE) TransformSensor nodes in different locations use the
union of all boxes to check for enter and exit, detecting enter and exit for all instances
of the box, and sending enter/exit events appropriately. For non-overlapping bounding
boxes, position_changed and orientation_changed events are calculated relative to
the coordinate system associated with the bounding box in which the proximity was
detected.
Warning: results are undefined if boxes overlap for multiply instanced TransformSensor nodes.
Warning: a TransformSensor node with a zero-volume box (i.e. any size dimension equal to
0.0) cannot generate events, equivalent to enabled=false.
Warning: unlike TouchSensor nodes, there is no notion of a TransformSensor node lower in
the scene graph grabbing events. |

Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.

Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.

TriangleStripSet |
[inherits X3DComposedGeometryNode]
TriangleStripSet is a geometry node containing a Coordinate|CoordinateDouble node,
and can also contain Color|ColorRGBA, Normal and TextureCoordinate nodes.
Hint: color, normal and texCoord values are applied in the same order as coord values.
Hint: insert a Shape node before adding geometry or Appearance.
Hint: for advanced extensibility, authors can substitute a type-matched ProtoInstance
node (with correct containerField value) for contained node content. |

| normal |
[normal accessType inputOutput, type SFNode singleton, NULL node] [X3DNormalNode]
Single contained Normal node that can specify perpendicular vectors for corresponding
vertices to support rendering computations, applied according to the normalPerVertex
field.
Hint: useful for special effects. Normal vector computation by 3D graphics hardware is
quite fast so adding normals to a scene is typically unnecessary.
Warning: normal vectors increase file size, typically doubling geometry definitions. Normal
vectors are rapidly computed at run time by GPUs and thus are rarely needed in model
files if no special effects are expected. |

| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| stripCount |
[stripCount accessType initializeOnly, type MFInt32 CDATA #IMPLIED] (3,+β)
stripCount array provides number of vertices in each strip.
Warning: do not exceed number of points in contained Coordinate|CoordinateDouble node. |
| ccw |
[ccw accessType initializeOnly, type SFBool (true|false) "true"]
ccw defines clockwise/counterclockwise ordering of vertex coordinates, which in
turn defines front/back orientation of polygon normals according to Right-Hand Rule
(RHR).
Hint: a good debugging technique for problematic polygons is to try changing the value
of ccw, which can reverse solid effects (single-sided backface culling) and normal-vector
direction.
Warning: consistent and correct ordering of left-handed or right-handed point sequences is
important throughout the coord array of point values.
Hint: clockwise https://en.wikipedia.org/wiki/Clockwise |
| colorPerVertex |
[colorPerVertex accessType initializeOnly, type SFBool (true|false) "true"]
Whether Color|ColorRGBA values are applied to each point vertex (true) or to each
polygon face (false).
Warning: the provided value of TriangleStripSet colorPerVertex field is ignored and always
treated as true.
Warning: if child Color|ColorRGBA node is not provided, then geometry is rendered using corresponding
Appearance and material/texture values.

Whether Normal node vector values are applied to each point vertex (true) or to
each polygon face (false).
Hint: if no child Normal node is provided, the X3D browser shall automatically generate
normals, using creaseAngle to determine smoothed shading across shared vertices. |
| solid |
[solid accessType initializeOnly, type SFBool (true|false) "true"]
Setting solid true means draw only one side of polygons (backface culling on), setting
solid false means draw both sides of polygons (backface culling off).
Hint: mnemonic "this geometry is solid like a brick" (you don't render the inside of a
brick).
Warning: default value true can completely hide geometry if viewed from wrong side!
Hint: if in doubt, use solid='false' for maximum visibility.
Hint: accessType relaxed to inputOutput in order to support animation and visualization.
|
| containerField |
[containerField type NMTOKEN "geometry"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different

Viewpoint |
[inherits X3DViewpointNode]
Viewpoint provides a specific location and direction where the user may view the
scene. Viewpoints are the primary way for a user to navigate within a scene, and for
an author to show critical aspects of a model.
Hint: a sequence of good Viewpoints with understandable descriptions can provide a guided
tour of a model.
Hint: the currently bound NavigationInfo node has a major effect on how a user might change
viewing position and orientation after reaching this Viewpoint.
Hint: consider paired Viewpoint/NavigationInfo node combinations by defining ROUTE connections
between corresponding isBound/set_bind fields.
Hint: consider how users might interact with the current X3D model, either standalone
or as an Inline within a larger parent scene.
Hint: Background, Fog, GeoViewpoint, NavigationInfo, OrthoViewpoint, TextureBackground
and Viewpoint are bindable nodes, meaning that no more than one of each node type
can be active at a given time.
Hint: GeoViewpoint OrthoViewpoint and Viewpoint share the same binding stack, so no more
than one of these nodes can be bound and active at a given time.
Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint,
TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
Avoid this authoring pattern.
Warning: do not include GeoViewpoint OrthoViewpoint or Viewpoint as a child of LOD or Switch,
instead use ViewpointGroup as parent to constrain location proximity where the viewpoint
is available to user.
Hint: Regardless of viewpoint jump value at bind time, the relative viewing transformation
between user's view and defined position/orientation is stored for later use when
un-jumping (returning to the viewpoint when subsequent viewpoint is unbound).
Hint: customizable design pattern for dedicated Viewpoint/NavigationInfo pair: <Viewpoint
DEF='SpecialView'/> <NavigationInfo DEF='SpecialNav'/> <ROUTE fromNode='SpecialView'
fromField='isBound' toNode='SpecialNav' toField='set_bind'/>

The navigationInfo field defines a dedicated NavigationInfo node for this X3DViewpointNode.
The specified NavigationInfo node receives a set_bind TRUE event at the time when
the parent node is bound and receives a set_bind FALSE at the time when the parent
node is unbound.
Hint: allows simple integration of custom navigation associated with each Viewpoint according
to user needs at that location. |
| viewAll |
[viewAll accessType inputOutput, type SFBool (true|false), false]
Viewpoint is automatically adjusted to view all visible geometry. Typically centerOfRotation
is shifted to center of current bounding box and view is zoomed in or out until all
visible objects are viewed.
Hint: no collision detection or proximity sensing occurs when zooming.
Warning: if needed, near and far clipping planes shall be adjusted to allow viewing the entire
scene.

Hint: the currently bound NavigationInfo node has a major effect on how a user might change
viewing position and orientation after reaching this Viewpoint.
Hint: consider paired Viewpoint/NavigationInfo node combinations by defining ROUTE connections
between corresponding isBound/set_bind fields.
Hint: include space characters since a description is not a DEF identifier. Write short
phrases that make descriptions clear and readable.
Warning: without description, this Viewpoint is unlikely to appear on browser Viewpoint menus.
Hint: many XML tools substitute XML character references for special characters automatically
if needed within an attribute value (such as & for & ampersand character, or "

[fieldOfView accessType inputOutput, type SFFloat CDATA "0.7854" (0,Ο)]
Preferred minimum viewing angle from this viewpoint in radians, providing minimum
height or minimum width (whichever is smaller). Small field of view roughly corresponds
to a telephoto lens, large field of view roughly corresponds to a wide-angle lens.
Hint: modifying Viewpoint distance to object may be better for zooming.
Warning: fieldOfView may not be correct for different window sizes and aspect ratios.

VolumePickSensor |
(X3D version 3.2 or later) [inherits X3DPickSensorNode]
VolumePickSensor tests picking intersections using the pickingGeometry against the
pickTarget geometry volume.
Hint: sort order is based on distance between centers of the bounds of the picking geometry
and the picked geometry.
Warning: pickingGeometry volume is defined by the convex hull of the enclosing planes of
the provided X3DGeometryNode. If the provided volume is not manifold, pick results
are undefined.
Hint: a pick is successful if any vertex of the pickTarget geometry intersects the volume
defined by the pickingGeometry.
Hint: Sorting is defined based on distance between the centers of the bounds of the picking
geometry and the picked geometry.
Hint: picking is performed between rendered frames of the event model. An author sets
up the picking request in one frame by placing a LinePickSensor in the desired location.
At the start of the next frame, any picking intersections are reported by the pick
sensor.
Hint: picking notification is performed at the start of the frame for all enabled pick
sensors once all other sensors are processed.
Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model
https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/concepts.html#ExecutionModel

| description |
[description accessType inputOutput, type SFString CDATA #IMPLIED]
Author-provided prose that describes intended purpose of the node.
Hint: many XML tools substitute XML character references for special characters automatically
if needed within an attribute value (such as & for & ampersand character, or "

| enabled |
[enabled accessType inputOutput, type SFBool (true|false) "true"]
Enables/disables node operation. |
| isActive |
[isActive accessType outputOnly, type SFBool #FIXED ""]
isActive indicates when the intersecting object is picked by the picking geometry.
Output event isActive=true gets sent once a picked item is found. Output event isActive=false
gets sent once no picked item is found.
Warning: it is an error to define this transient outputOnly field in an X3D file, instead
only use it a source for ROUTE events. |
| intersectionType |
[intersectionType accessType initializeOnly, type SFString CDATA ( GEOMETRY|BOUNDS ) "BOUNDS"]
intersectionType specifies precision of the collision computation.
Hint: intersectionType constants may be extended by the browser to provide additional
options.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |
| matchCriterion |
[matchCriterion accessType inputOutput, type SFString CDATA ( MATCH_ANY|MATCH_EVERY|MATCH_ONLY_ONE ) "MATCH_ANY"]
defines whether the intersection test (i.e. pick) by this X3DPickSensorNode must
match one or more objectType. Specifically MATCH_ANY means any match of objectType
values is acceptable, MATCH_EVERY means that every objectType value in this node shall
match an objectType value in the X3DPickableObject, and MATCH_ONLY_ONE means that
one and only one objectType value can match. |
| objectType |
[objectType accessType inputOutput, type MFString CDATA ( ALL|NONE|TERRAIN|... ) "ALL"]
The objectType field specifies a set of labels used in the picking process. Each
string specified is treated as an independent label that needs to be matched against
the same type in one of the pick sensor instances.
Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to
intersect a pick sensor with objectType value "GROUND" fails since the objectType
values do not match.
Example: the special value "ALL" means that each node is available for picking regardless
of the type specified by the pick sensor.
Example: the special value "NONE" effectively disables all picking for this node and is the
equivalent of setting the pickable field of the corresponding PickableGroup to false.
Hint: authors may define any value for objectType.
Hint: MFString arrays can have multiple values, so "separate each individual string" "by
using quote marks". |
| sortOrder |
[sortOrder accessType initializeOnly, type SFString CDATA ( ANY|CLOSEST|ALL|ALL_SORTED|... ) "CLOSEST"]
The sortOrder field determines the order provided for picked output events.
Example: ANY means any single object that can satisfy picking conditions for this pick sensor.
Consistency of results is not guaranteed.
Example: ALL means that every object that satisfies the picking conditions for this pick
sensor shall be returned.
Example: ALL_SORTED means that every object that satisfies the picking conditions for this
pick sensor shall be returned with the order of the output fields provided in a distance-sorted
order from closest to farthest away. The exact algorithm for sorting is defined by
the individual node definitions.
Example: CLOSEST means that the closest object by distance that satisfies the conditions
of this pick sensor. *The exact algorithm for distance determination shall be defined
by individual node definitions*.
Hint: browser implementations may define additional values and algorithms beyond these
four required values.
Warning: do not wrap extra quotation marks around these SFString enumeration values, since
"quotation" "marks" are only used for MFString values. |

DEF defines a unique ID name for this node, referenceable by other nodes.
Hint: descriptive DEF names improve clarity and help document a model.
Hint: well-defined names can simplify design and debugging through improved author understanding.
Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions |
| USE |
[USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other
attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes)
can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except
for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the
scene. |
| enabled |
[enabled accessType inputOutput, type SFBool (true|false) "true"]
Enables/disables node operation. |
| direction |
[direction accessType inputOutput, type SFVec3f CDATA "1 0 0"]
direction in which wind is travelling in the form of a normalized, unit vector.
|
| gustiness |
[gustiness accessType inputOutput, type SFFloat CDATA "0.1"] [0,+β)
gustiness specifies how much wind speed varies from the average speed.
Hint: wind speed variation is calculated once per frame and applied equally to all particles.
|
| speed |
[speed accessType inputOutput, type SFFloat CDATA "0.1"] [0,+β)
Initial linear speed (default is m/s) imparted to all particles along their direction
of movement. |
| turbulence |
[turbulence accessType inputOutput, type SFFloat CDATA "0.1"] [0,1]
turbulence field specifies how much the wind acts directly in line with the direction,
and how much variation is applied in directions other than the wind direction.
Hint: this is determined per-particle to model how each is effected by turbulence. |
| containerField |
[containerField type NMTOKEN "physics"]
containerField is a field-label prefix indicating this node's field relationship
to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need
to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children'
for Group node, containerField='proxy' for hidden proxy shape within a Collision node,
etc.
Warning: containerField attribute is only part of XML encoding for X3D scenes, and corresponds
to the always-declared field names in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different
than the corresponding DEF declaration of that node.

X3D |
[X3D statement]
X3D is the top-most XML element for an Extensible 3D (X3D) Graphics model.
The X3D element contains a single head element for metadata, and a single Scene element
which is root node of the 3D scene graph.
Hint: for more on XML declaration and DOCTYPE (DTD) statements, which precede the X3D
statement, see https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Validation
Hint: each X3D model has a tree structure. Wikipedia: Tree (data structure) https://en.wikipedia.org/wiki/Tree_(data_structure)
Hint: X3D model is also a form of Directed Acyclic Graph (DAG), which has no loops and
helps to ensure efficient processing.
Hint: additional attributes are under consideration for use when embedding X3D version
4 scenes within HTML version 5 web pages.
