Research on Collision Detection Algorithm Based on OBB

To enhance the real-time and accuracy of collision detection in virtual environment, introduces oriented bounding box (OBB) technology of hierarchical bounding box collision detection algorithm:construction of bounding box, generation of bounding box tree, implementation of collision detection algorithm,overlap judgement of bounding box. Collision detection algorithm based on OBB in this article is applied to solve the problem of collision detection between rigid bodies.
