Almost a 3d engine (OpenGL)
This is my first attempt at a 3d engine. It's quite old. Features nice octree code, md2 loading and animation, mostly good collision detection (but really f*ced up when you run into a corner) - taken from peroxide.dk, and that's mostly it for now. If you would like to make modifications to this code, then send them to cone3d@hot.ee. And know that this is mostly an abandoned project so don't expect me to solve problems for you.

Octree Demo (OpenGL)
This is a really nice demo based on the octree code (from the opengl tut 3). Features silhouette rendering, ray-triangle collision detection and cel-shading (based on NeHe Lesson 38). Heightmap optional, LOD to be included. Mail the author at da.gahre@web.de and let him know if you like the demo.

Sopa (SDL)
This is a little SDL game by Pedro Santos (pedro__santos@iol.pt). The object of the game is to find all the required words inside the "letter grid". It's like a crossword puzzle. Let the author know if you like this game or find it useful in some way.
