I have some code which does this (in C++) but don't have it ATM. :-( I have notes from the class I took about it, though, if you'd like them. Gourad should be possible if you can find a gradient filling function but Phong *needs* pixel-by-pixel or a special function in the library. -- Justin Patrin
