Package org.web3d.x3d.sai.Geometry2D

Interface Rectangle2D

All Superinterfaces:

X3DGeometryNode, X3DNode

All Known Implementing Classes:

Rectangle2D

public interface Rectangle2D
extends X3DGeometryNode

Rectangle2D is a geometry node that defines a 2D rectangle in X-Y plane.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. Rectangle2D node tooltip: [X3DGeometryNode] Rectangle2D is a geometry node that defines a 2D rectangle in X-Y plane.

• Hint: insert a Shape node before adding geometry or Appearance. Examples: X3D Example Archives, X3D for Web Authors, Chapter 10 Geometry 2D https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter10Geometry2D

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).

Method Details

getMetadata

X3DMetadataObject getMetadata()

Provide org.web3d.x3d.sai.Core.X3DMetadataObject instance (using a properly typed node) from inputOutput SFNode field metadata.

Tooltip: [X3DMetadataObject] Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

• Hint: X3D Architecture 7.2.4 Metadata https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/components/core.html#Metadata

Specified by:

getMetadata in interface X3DGeometryNode

Specified by:

getMetadata in interface X3DNode

Returns:

value of metadata field

• X3D Scene Authoring Hints: Metadata Nodes

setMetadata

Rectangle2D setMetadata(X3DMetadataObject newValue)

Accessor method to assign org.web3d.x3d.sai.Core.X3DMetadataObject instance (using a properly typed node) to inputOutput SFNode field metadata.

Tooltip: [X3DMetadataObject] Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

• Hint: X3D Architecture 7.2.4 Metadata https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/components/core.html#Metadata

Specified by:

setMetadata in interface X3DGeometryNode

Specified by:

setMetadata in interface X3DNode

Parameters:

newValue - is new value for the metadata field.

Returns:

Rectangle2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

• X3D Scene Authoring Hints: Metadata Nodes

getSize

float[] getSize()

Provide array of 2-tuple float results from initializeOnly SFVec2f field named size.

Tooltip: 2D dimensions of Rectangle2D.

• Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time.
• Hint: for size animation, modify the scale of a parent/ancestor Transform node instead.

Returns:

value of size field

setSize

Rectangle2D setSize(float[] newValue)

Accessor method to assign 2-tuple float array to initializeOnly SFVec2f field named size.

Tooltip: 2D dimensions of Rectangle2D.

• Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time.
• Hint: for size animation, modify the scale of a parent/ancestor Transform node instead.

Parameters:

newValue - is new value for the size field.

Returns:

Rectangle2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

getSolid

boolean getSolid()

Provide boolean value from initializeOnly SFBool field named solid.

Tooltip: 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.
• Warning: solid false not supported in VRML97.
• Hint: accessType relaxed to inputOutput in order to support animation and visualization.

Returns:

value of solid field

setSolid

Rectangle2D setSolid(boolean newValue)

Accessor method to assign boolean value to initializeOnly SFBool field named solid.

Tooltip: 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.
• Warning: solid false not supported in VRML97.
• Hint: accessType relaxed to inputOutput in order to support animation and visualization.

Parameters:

newValue - is new value for the solid field.

Returns:

Rectangle2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
