Documentation

Encapsulates OpenGL drawing primitives, geometry and optional binding of normal, color and texture coordinates. Used for representing the visible objects in the scene. State attributes for a GeoSet are maintained in GeoState which the GeoSet maintains a referenced counted pointer to. Both GeoSet's and GeoState's can be shared for optimal memory usage and graphics performance.
