This is a software-based opengl subset (which means it's not an opengl implementation, it just looks a bit like it).
This rendering engine was used in the TMDC winning demo "Litterae Finis".
The GL subset is based on TinyGL by Fabrice Bellard, with a few little changes;
- Lots of code I did not need was torn out (like different output interfaces)
- All rendering changed to 32 bit. Not everything is tested, so this change may still need work..
- Mipmap support for textures
- Non-standard gl extension to poke directly at texture data for demo purposes
- Matrix math changed to use glm
- Possibly other ugly changes that I don't recall right now
The demo source shows how to draw some 3d stuff with the textgl thingy, as well as how to poke directly at the "bitmap" framebuffer, how to turn that into ascii art with TextFX7, how to poke directly at the "text mode" framebuffer, and finally how to dump the result to console with TextFX7.
All in all, this should be more than enough for you to do some bitchin' text mode demos.
