I don't want to know where it intersects, only if intersects at all. I really need something fast, because i'm using this in a glsl pixel shader, and the algorithm i currently use works, but it's slow. The polygon is given by 4 vectors and one normal.

They have a really good matrix of the best intersection algorithms.
