This function takes a set of XYZ points and projects them onto the 2D screen (quite well, I might add). I'm currently writing a 3D isometric engine a la Dungeon Keeper, Syndicate Wars, and Ultima IX (before it was turned into a 3D action game). Which means that I DON'T want to correct the perspective with respect to the Z axis. Anyone out there know a way to do this with Allegro's current functions, or am I going to have to come up with a no_persp_project? (Which, naturally, I'll share with everyone once it gets debugged). Thanks. Badman
