TGLObject Base-class for direct OpenGL renderers. This allows classes to circumvent passing of TBuffer3D and use user-provided OpenGL code. By convention, if you want class TFoo : public TObject to have direct rendering you should also provide TFooGL : public TGLObject and implement abstract functions SetModel() and SetBBox(). TAttBBox can be used to facilitate calculation of bounding-boxes. See TPointSet3D and TPointSet3DGL.

Update bounding box from external source. We call abstract SetBBox() and propagate the change to all attached physicals.
Checks if obj is of proper class and sets the model. Protected helper for subclasses.
Set axis-aligned bounding-box. Protected helper for subclasses.
Set axis-aligned bounding-box. Protected helper for subclasses.
Recursively search cls and its base classes for a GL-renderer class.
Return direct-rendering GL class for class isa. Zero is a valid response.
