Abstract
One embodiment of the present invention sets forth a technique for efficiently performing broad phase collision detection using parallel spatial subdivision. The technique involves organizing candidate objects according to a hashed representation of each object centroid, constructing a cell identification (ID) array, sorting the cell ID array, creating a collision cell list, and traversing the collision cell list. The result is a candidate list of object groups that may collide, based on an initial assessment of spatial proximity. Whether a given pair of objects actually collides is determined by a precise narrow phase collision analysis.
