基于两级非渗透滤波的连续碰撞检测算法
Continuous collision detection algorithm based on two-level non-penetration filtering
摘要
Abstract
In order to improve the efficiency of collision detection for high resolution models during physical simulations,this paper proposed a method based on two-level non-penetration filtering and primitives which were impossible to collide were quickly culled.Firstly,the primitives which had no overlaps were culled in the first level through adding an extra hierarchy bounding box to primitives.Then,it applied an algebraic filter to the primitives passed the first level culling for low-level filtering.Experimental results show that the proposed method can not only effectively detect the collision information,but also have a robust filtering feature when intensive deformation occurs.关键词
