Class idx3d_Object

java.lang.Object
  idx3d.idx3d_CoreObject
      idx3d.idx3d_Node
          idx3d.idx3d_Object

public class idx3d_Object
extends idx3d_Node

Represents a three dimensional shape.

Version:

4.1 2006-02-21 Werner Randelshofer: Avoid unecessary object creation.
4.0 2004-08-29 Werner Randelshofer: Changed superclass to idx3d_Node. Moved variables 'parent' and 'isDirty' to superclass.
3.2 2003-12-18 Werner Randelshofer: Method incorporateGeometry(idx3d_Object) added. Method removeDegeneratedTriangles iterates in reverse order to prevent index mismatches when removing triangles. Moved responsibility for texture location from class idx3d_Vertex to this class. Dependency note: This change also requires changes in idx3d_Vertex, idx3d_Triangle, idx3d_TextureProjector, idx3d_Rasterizer. Method getTriangleCount added.
