Fast and reliable collision culling using GPUs and OpenGL occlusion query

This paper presents a fast and reliable collision culling algorithm using OpenGL API occlusion query and vertex arrays, on graphics processors for handling complex objects with tens of thousands of polygons, including objects undergoing deformation and non-rigid motion. The new algorithm overcomes a major limitation of earlier GPU-based collision detection algorithms and is able to perform reliable interference queries. It improve the rendering throughput by using vertex arrays and use GL_NV_occlusion_query to perform the visibility queries.
