A game and 3d-engine being developed by SamJansen and JesseBaker.
Currently it works a little more like a QuakeIII level viewer than anything else. Basically, SamJansen wrote a QuakeIII level importer so the development process had decent size & quality levels to work with. The levels aren't rendered entirely, certain things are missing (mainly animated textures and the like).

Though the project has mainly been coded in MicrosoftWindows with Microsoft Visual C++ .NET, it also works in Linux using SimpleDirectMediaLayer, or SDL.
There are a number of people finding this page through google mostly looking for information on collision detection using opcode, and how to read md3 models etc, perhaps you would like to describe your experiences with these things here for others benefit?
