OBB

From DmWiki

A OBB is an Oriented Bounding Box. Just like an AABB, it is an rectangular box (2D, 3D, ...) that thightly bounds a object. In contrary to the AABB, the OBB does not have to be oriented aling the axises. It can therefore more thighly fit the object to be bounded, but this comes a cost: an OBB requires more storage and it is more complex to do intersection tests with OBBs
