A Three-layer Hybrid Bounding Volume Hierarchy for Collision Detection
Y. Liu, H. Wang, Y. Pei
The Real-time collision detection (CD) is an important problem in virtual environments. This paper proposes a novel algorithm called SBBK which combines three different kinds of bounding volumes (BVs) together when constructing the hybrid bounding box tree for the object to make CD more accurate and faster. For illustration, CD experiments are carried out to show its advantages. The experiment results show that SBBK has better time performance and accuracy than the single AABB BV algorithm especially in dealing with CD in large-scale and complex environments. The proposed algorithm SBBK can effectively accelerate CD and improve the accuracy and thus can be used to solve CD problem in virtual environment or large-scale, complex environments.
