All Implemented Interfaces:

WorldInfo, X3DChildNode, X3DInfoNode, X3DNode

public class WorldInfo
extends X3DConcreteNode
implements WorldInfo

WorldInfo contains a title and simple persistent metadata information about an X3D scene. This node is strictly for documentation purposes and has no effect on the visual appearance or behaviour of the world.

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. WorldInfo node tooltip: [X3DInfoNode] WorldInfo incldes a browsesr-displayable title and persistent string information about an X3D scene. For X3D4 models, WorldInfo can also contain a single MetadataSet node with further metadata information about the scene.

• 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.
• Hint: WorldInfo is part of Core component and Core profile. https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/components/core.html#t-CoresupportLevels
• Hint: X3D for Web Authors, Chapter 15, Metadata Information https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter15-Metadata/Chapter15-MetadataInformation.html

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.
