Game Development News and Resources, great site for any game developer... pro or amateur.
THE 3D Graphics API of choice (at least by us).
Houses the DevIL site and a great contributer of the Open Source movement.
Daily geek news that actually matters.
Largest collection of file format specs out there.
Another top-notch image library. Hey, gotta give the competitors a chance. ;-)
Definitely the site to go to if you want to get your feet wet in OpenGL coding. Even most of the tutorials have been converted to use DevIL by Denton.
The site of an amazing 3D engine. The author releases quite a few papers and source code to various things, so it's definitely worth a look.
