For those interested on polygon-level collision you can read a tutorial that yin_nadie writed to explain how we did the accurate collisions with meshes in the game "Demens descendio"

The page have been updated with the second part of the tutorial about per-polygon collisions.
This one explains how to move throught the 3D mesh once you have the collision data.
Enjoy!

nice!
Too bad I don't have time to read it now, but I most certainly will read it soon!

Thanks a lot!!!
