Accidentally I'm working on 3D projection and motion for the ST right
now (rotation, reflection, translation etc.). I use 4D homogene
coordinates to achieve things, so each movement can be presented by
applying a matrix multiplication to an object (in fact to the 4x4
matrix that puts the object in space). Apart from one function that is
in assembly (matrix multiplication) all stuff is in C. If there is
enough interest, I'll post it. It works already, but I want it to be faster
still (speed++), although it can handle wire models real-time.
Anyone interested, send me a mail, specifying where I should put the stuff
(this newsgroup, comp.sources.atari.st or e-mail).
Leo (the mathemagician).
