Class Background

java.lang.Object

org.web3d.x3d.jsail.X3DConcreteElement

org.web3d.x3d.jsail.X3DConcreteNode

org.web3d.x3d.jsail.EnvironmentalEffects.Background

All Implemented Interfaces:

X3DBindableNode, X3DChildNode, X3DNode, Background, X3DBackgroundNode

public class Background
extends X3DConcreteNode
implements Background

Background simulates ground and sky, using vertical arrays of wraparound color values.

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. Background node tooltip: [X3DBackgroundNode] Background simulates ground and sky, using vertical arrays of wraparound color values. Background can also provide url addresses for backdrop textures on all six sides.

• 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.
• 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: Background node is not sensed by LoadSensor due to node typing and multiple-image ambiguity, alternatively utilize TextureBackground node with multiple ImageTexture nodes each referenced inside LoadSensor.
• Hint: X3D Example Archives, Basic, Universal Media Panoramas https://www.web3d.org/x3d/content/examples/Basic/UniversalMediaPanoramas

Note that SFColor provides a variety of color constants.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

Specified by:

setCssStyle in class X3DConcreteNode

Parameters:

newValue - is new value for the style field.

Returns:

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

setCssStyle

public Background setCssStyle(SFString newValue)

Assign typed object value to SFString cssClass field, similar to setCssStyle(String).

Parameters:

newValue - is new value for the style field.

Returns:

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

setUSE

public Background setUSE(Background DEFnode)

Assign a USE reference to another DEF node of same node type, similar to setUSE(String).

Warning: note that the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.

Parameters:

DEFnode - must have a DEF value defined

Returns:

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

addComments

public Background addComments(String newComment)

Add comment as String to contained commentsList.

Specified by:

addComments in class X3DConcreteElement

Parameters:

newComment - initial value

Returns:

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

See Also:

• X3D Architecture, clause 7.2.5.1 Organization

addComments

public Background addComments(String[] newComments)

Add comments as String[] array to contained commentsList.

Specified by:

addComments in class X3DConcreteElement

Parameters:

newComments - array of comments

Returns:

Background - namely this same object to allow sequential method pipelining (i.e. consecutive setAttribute method invocations).

addComments

public Background addComments(CommentsBlock newCommentsBlock)

Add CommentsBlock to contained commentsList.

Specified by:

addComments in class X3DConcreteElement

Parameters:

newCommentsBlock - block of comments to add

Returns:

Background - namely this same object to allow sequential method pipelining (i.e. consecutive setAttribute method invocations).

findElementByNameValue

public X3DConcreteElement findElementByNameValue(String nameValue)

Recursive method to provide object reference to node or statement by name attribute, if found as part of this element or in a contained element. Elements with name fields include meta, Metadata* nodes, field/fieldValue, ProtoDeclare/ExternProtoDeclare/ProtoInstance, CAD and HAnim nodes.

Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

Warning: more than one element may be found that has the same name, this method does not handle that case.

Specified by:

findElementByNameValue in class X3DConcreteElement

Parameters:

nameValue - is value of the name field being searched for in this element and child elements(if any)

Returns:

object reference to found element, null otherwise

See Also:

• findNodeByDEF(String)
• X3DConcreteElement.hasAncestorScene()
• X3DConcreteElement.findAncestorX3D()

findElementByNameValue

public X3DConcreteElement findElementByNameValue(String nameValue,
 String elementName)

Recursive method to provide object reference to node or statement by name attribute, if found as part of this element or in a contained element. Elements with name fields include meta, Metadata* nodes, field/fieldValue, ProtoDeclare/ExternProtoDeclare/ProtoInstance, CAD and HAnim nodes.

Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

Warning: more than one element may be found that has the same name, this method does not handle that case.

Specified by:

findElementByNameValue in class X3DConcreteElement

Parameters:

nameValue - is value of the name field being searched for in this element and child elements(if any)

elementName - identifies the element of interest (meta MetadataString ProtoDeclare CADassembly ProtoInstance HAnimHumanoid etc.)

Returns:

object reference to found element, null otherwise

See Also:

• findNodeByDEF(String)
• X3DConcreteElement.hasAncestorScene()
• X3DConcreteElement.findAncestorX3D()

hasElementByNameValue

public boolean hasElementByNameValue(String nameValue,
 String elementName)

Recursive method to determine whether node or statement with given name attribute is found, meaning both objects are attached to same scene graph.

Parameters:

nameValue - is value of the name field being searched for in this element and child elements(if any)

elementName - identifies the element of interest (meta MetadataString ProtoDeclare CADassembly ProtoInstance HAnimHumanoid etc.)
