  idx3d.idx3d_CoreObject
      idx3d.idx3d_Node

Direct Known Subclasses:

idx3d_Group, idx3d_Object

public class idx3d_Node
extends idx3d_CoreObject

idx3d_Node objects divide into group node objects and leaf node objects. idx3d_Group node objects serve to group their child node objects together according to the group node's semantics. Leaf nodes specify the geometric elements that idx3d uses in rendering; specifically, geometric objects, and lights.
