Annex F Attribute table

Defines an additional set of functionality of the Programmer's hierarchical Interactive Graphics System. The object is to satisfy basic application requirements in the areas of lighting and shading and specifies additional primitives and functionality for controlling of the rendering of 3D objects. Depends on coexistence of the functions and functionality defined in ISO/IEC 9592/1, and is intended to extend that functionality in the above areas.
