Hi. My Death Rally actually features a convex polyhedron (max. 257-gon) drawing routine with the ability to use fill patterns. It has but one drawback: you need two framebuffers for it to work. (However, one of these is only needed at the time of drawing the polygon.) You can drop me a mail, and we'll see what we can do about it. I am anyway willing to release the source of the game, when it's finished. PG
