SetDefaultPosition();

CGlObject Base class for OpenGl objects like buffers and models.

CGlRenderNode A unit of renderable geometry and the associated state information needed for rendering...

CGlState Class to encapsulate Rendering state so that a set of user-selected GL state options can be ...
