gpu940 - Summary
Gpu940 is a soft 3D renderer that can do many rendering types, including true perspective texture mapping/lighting. The software is designed to operate as a separate process. It's mainly targeted at GPH's GP2X (http://www.gp2x.com) but can be used on other platforms as well.
Commands are sent to the "GPU" using a cyclic buffer. On PC, this buffer is mmapped and shared by the "GPU" and the client.
The GPU performs clipping, projection and drawing. Geometry can be drawn onto as many video buffers as you need (not limited to 2). Textures and Z-buffers are like video buffers, so that any texture or z-buffer can be drawed onto, and that any previous video buffer can serve as a texture or z-buffer.

As requested, some files in the download section :
gpu940_binaries_2-0-0.tgz : the binary files and headers, usefull to start developping without the need to build it from sources
egoboo2x_binaries_2-0-0.tgz : the egoboo binary (working with gpu940 in the previous file) to be copied inplace of the former one to add the lighting effects.

After the rasterizer was a little tweacked to help GCC optimize things, gpugears now runs at 30FPS.
Also, Egoboo2X now have lights !

Due to some troubles with the mailing list, it was reseted. All subscribtions are lost, except for the few people whose notification message were still in my inbox.
Everything's working fine now, please suscribe again if you are still interrested in gpu940.

Egoboo2x is the first game ported to GP2X that uses gpu940 and it's opengl-like library.
It's running without overclocking at around 12fps, which is just playable. Most of fancy visual effects were compiled out, though.
