Abstract:Our work presents a new, faster oriented bounding box (OBB) algorithm which is especially helpful and beneficial for building box hierarchies for articulated, human-like figures. One of the largest critiques of using OBBs is that they can be very slow to update. Our main contribution lies in the fast update of the box hierarchy when the joints in the articulation hierarchy are updated. Our method provides a comparable fit to other methods of calculating loose fitting OBBs but with considerably faster speed.
