Based on the designing requirement of 3D garment CAD, a low level collision detection algorithm was proposed with the idea of Cyrus Beck clipping method. The comparison was made between the new algorithm and the Moore Wilhelms.

• 针对服装 CAD系统的设计要求 ；提出了一种基于 Cyrus- Beck剪切算法思想的低阶碰撞检测算法 ；并与 Moore- Wilhelms算法的检测时间进行了比较 .
