1. Example programs for Mesa (and OpenGL in general) Mesa demonstration programs, SGI sample code, and source code examples from the _OpenGL Programming Guide_ ("the Red Book"), the _OpenGL Reference Manual_ ("the Blue Book") and _Programming OpenGL for the X Window System_ ("the Green Book") Although some of the demos generate "pretty pictures", they are much more valuable in source code form. They were written in the first place for the OpenGL programmer to study and learn from. In order to compile the demos you'll need a package providing libgl-dev, as well as libglut-dev.
