Selected C Code

This directory contains selected ANSI C source code from Chapters 2, 3,
5, 7, 9, 11, 13, and 14 of "Introduction to Computer Graphics."  Some
selections are just code fragments which are meant to be augmented
to produce a substantive program.  Others are complete, ready-to-run
programs.  Where possible, all code has been successfully compiled and,
for complete programs, executed and tested.
