Graphics Source Codes

I've written, converted, modified or simply admired a few graphics routines, libraries, and packages.

I don't mind receiving your comments, compliments, corrections or complaints, but please be warned that I will not do your damn homework.

For each package listed below, if you click on its name, you can see an expanded explanation of its purpose, a list of its contents, and copy the entire source code file, a sample calling program, or the results of running the calling program.

Currently available software includes:
