AN OCTREE ALGORITHM FOR COLLISION DETECTION USING SPACE PARTITION

This paper presents an octree algorithm for collision detection,employing the space partition technique, which drastically reduces the computation time consumed in dynamic collision detection during computer simulation. The simulated objects are represented in octrees. The space partition technique divides the simulated space based on a criterion derived from the geometric interdependence of the two octrees, so the relations (overlap or separate) among the nodes in the octreescan be directly pinpointed. Since heuristic procedures are excluded, time consumption for collision detection is greatly reduced. Further, simple arithmetic is enough to cover the problem.
