Hi guys,

I'm implementing the 2D Separting Axis Theorom (swept) and need to figure out the contact points when a collision occurs. I think I have to project the vertices on to the collision normal and find the maximum values of one polygon and the minimum of the other, but how do I know which polygon should have the min and which the max ?

Are there any clear tutorials on finding the contact points ?

Thanks.
