So far I have 2 AABB's, one stationary and one moving, checking against min(x,y,z) and max(x,y,z) of the 2 AABB's I can tell if they intersect.
Now I would like to implement a "slide against the wall" effect, therefore I need to get the normal of the colliding face, but I have troubles understanding how I can compute which face is colliding.
I googled a lot and found something about SAT ( http://www.codezealot.org/archives/55 ) but I am still confused, is this the only technique to get the colliding face or are there other options available?
I would appreciate some hints or pseudo code to get me started.
