I'm looking for an algorithm that allows me to know if a quadrilateral intersects another one. I'm not interested in the intersection itself, I just want to know if it exists.
I have found solutions like the one proposed here: https://math.stackexchange.com/questions/141798/two-quadrilaterals-intersection-area-special-case
But my problem is simpler than the person who wrote this post so there may be a simpler solution too.
