OpenGL interface

Overview

This goody implements protocol to interface to the openGL 3D graphics library. Although similar to GL, this differs in its function syntax and provides much more functionality; especially, light sources, textures etc.

The openGL interface may be used both with a true GL library, or with the freely available GL replacement MESA.
