IMO, Allegro's polygon routines could be optimised a little further, and you could speed upi the routines by using dot and cross products yourself instead of calling the relevant functions. Generally, people use Allegro's 3D routines (which are pretty basic) until they work out how to do it all themselves. The 3D math functions are useful, but since they are standard maths algorithms used in practically all 3D engines, most people re-write them to be more suited to the task in hand. This is, of course, what I have gathered from what several programmers have said to me in the past. I'm sure someone will prove me wrong, though.
