java.lang.Object javax.media.j3d.Locale
public class Locale
A Locale object defines a highresolution position within a VirtualUniverse, and serves as a container for a collection of BranchGrouprooted subgraphs (branch graphs), at that position. Objects within a Locale are defined using standard doubleprecision coordinates, relative to the origin of the Locale. This origin defines the Virtual World coordinate system for that Locale.
A Locale object defines methods to set and get its highresolution coordinates, and methods to add, remove, and enumerate the branch graphs.
For more information, see the Introduction to the Java 3D API and Scene Graph Superstructure documents.
