A simple question. I could probably come up with something but I doubt it would be optimal. This is for collision detection. I have the triangle''s coordinates, normal, and plane, the "point" is the point on the plane where the object''s movement vector intersects it. So if the point is within the triangle then the object is colliding with it. I have the point; I know how to do plane collision. ~CGameProgrammer( );

Gosh, there have been 3 or 4 threads about this recently, and more than one of those probably shows up in first page or two of threads in the forum. So you can find lots of discussion on this problem by browsing existing threads.

I''m going to give you my standard link for point-in-polygon tests:

Oh yeah, lol, on the second page there are about four of them right next to each other. I''ll start reading them now.
