| Abstract: | A fast collision detection algorithm is presented between complex models using graphics hardware. The algorithm is based on CULLIDE which using GPU to eliminate a subset of geometric primitives that are not in close proximity. A novel visibility-based classification scheme is described to compute potentially-colliding and collision-free subsets of objects and primitives, which considerably improves the culling performance. For balancing the load between CPU and GPU, precise intersection is calculated on GPU. |
