Edit Question
Title
Body
I have two rays on a 2D plane that extend to infinity, but both have a starting point. They are both described by a starting point and a vector in the direction of the ray extending to infinity. I want to find out if the two rays intersect, but I don't need to know where they intersect (it's part of a collision detection algorithm). Everything I have looked at so far describes finding the intersection point of two lines or line segments. Is there a fast algorithm to solve this?
