摘要：
Simulating the tree swaying in wind field fast and realistically is still a challenge in computer graphics. Collision detection plays a crucial role in enhancing the effect of simulating the swaying of a tree under different wind scale. Based on the branch position relationship analysis, the detection methods in all kinds of conditions were proposed. A novel collision detection algorithm was formed. Experiment results show that the novel algorithm can reduce the computing complexity and improve the efficiency compared to OBB algorithm.
