C Code for Interactive 3D Graphics
This software package was developed to provide the tools needed to
construct, visualize, and interact with a virtual environment.  The environment
is generated from a series of primitives called models which are linked
together and controlled through a hierarchial display map to create objects.
There can be multiple objects and any number of nodes (action blocks) within
a single object that link the primitives together. Author: Michael P. Schenck
