Abstract
In this paper, a new GPU based algorithm is proposed for detecting collisions between solid objects. The proposed algorithm is fast, precise, and applicable to large and complex objects with huge number of polygons. In our broad phase collision detection, a culling program based on the lattice structure is executed on GPU to efficiently exclude apparently non-colliding polygons. In the following narrow phase collision detection, parallel processing capability of GPU is used for detecting mutually penetrating polygons. A sample program is implemented and tested with complex examples.
