Triangle/Triangle 2D Collision Detection at Any Angle
Author
I've been searching for code on this for months, but I want to be able to have a function that accurately determines whether a collision has occured between two triangles (or even more for multiple collisions) in 2D at any angle. I also want to be able to do this with Quads. Been mainly testing quads though, and so far, everything I've tried has failed or was way off. Does anyone have any code that tests collisions on these polygons in 2D?

Whoops. Apparently I posted the same thread twice by accident trying to get it through with gamedev having server issues. Nothing a mod can't handle. :p
Here is a demo I did some time back, it uses the algorithm from PollyColly, but I can't seem to find the link.

Thanks for the algorithms you guys. I gotta convert them into another programming language though, but besides that, I'm being lead into the right track for a change. I'll be back if I run into problems.
