I was passing by, remembering the good old days :-)

Will you make it open-source? Do you use some kind of tricks to compute the rotation matrix? Optimizing this animal using linearized trigonometric functions gave me a few headaches...

Ill most likely release the source, or at least the source to the necessary routines.

There are a lot of shortcuts i guess but as far as the matrix code goes each element is 6-bits and uses specialized math routines/tables for speed.

I also do other things like multiply by reciprocal instead of a division for perspective etc.

Lately ive been working on 3D movement, tracking and collision routines etc (screenies in the other thread: viewtopic.php?p=67219#p67219)
