Class Locale

java.lang.Object

org.scijava.java3d.Locale

public class Locale
extends Object

A Locale object defines a high-resolution position within a VirtualUniverse, and serves as a container for a collection of BranchGroup-rooted subgraphs (branch graphs), at that position. Objects within a Locale are defined using standard double-precision 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 high-resolution 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.
