| Abstract: | Based on comprehensive analysis of common collision detection method,AABB bounding Boxes method is adopted in collision detection research of virtual orthodontics,through the construction of the bounding box binary tree,idiographic implement approach of collision detection is presented,and more basic geometry element collision detection are discussed.Simulation results indicate that collision detection satisfy request of three dimension and real time. |
