Real Time Collision Detection Using Depth Texture

The checking rates of most collision detection algorithms were influenced by the numbers of triangles in objects. We presented a novel algorithm to detect objects collisions in real time where an object is represented by its bounding box with depth map, and programmable graphics hardware is used to compare the depth of different objects to detect the collision of these objects during the texture depth mapping. We implemented the proposed algorithm and compared it with CULLIDE. The results show that our algorithm is more effective than CULLIDE and has fixed executive time to suit for real time applications.
