OBB Intersection volume

[hangt5]

I'v been messing around with my physics engine for a while now. I have a nice little rigid body system set up. Im currently working on collision detection. I can test for AABB's vs Pretty much anything and get good results. I just started working with OBB's. Using a lot of articles i have a pretty good OBB detection system. Im lost however on how to figure out the actual point of intersection for OBB's.

Could someone shed some insight into how i would find the point of intersection (or i guess intersection volume) between two OBB's? I need this so i can do proper collision response.

As always thanks in advanced.
