摘　　要： 提出一种基于细分曲面的三维服装柔性实体模拟算法 该算法将整个模拟过程分为两个阶段 :首先利用四点细分曲面造型方法生成三维服装刚性曲面 ,然后在刚性曲面基础上通过引入织物的物理模型来模拟三维服装柔性曲面 通过物理和几何模拟方法有机结合 ,算法有效解决了复杂衣片间的缝合问题 ,较大地提高了模拟的计算效率 同时 ,也提出了一种基于细分曲面层次数据结构的碰撞检测算法 ,有效提高了模拟速度 提出的算法已全部在所开发的三维虚拟服装试衣系统中得以实现 实验结果表明 :该算法具有模拟效率高。 Presented in this paper is an algorithm of 3 D garment dressing effect simulation based on subdivision scheme The simulation process is divided into two phases: in the first phase, 3 D garment rigid surface is rapidly generated by 4 point interpolatory subdivision scheme, and then on the basis of rigid surface, physical model of cloth is introduced to simulate 3 D virtual garment soft surface Combining the physical technique with the geometrical technique, the algorithm effectively deals with the sewing problem between complex patterns, and reduces the high computation cost of the physical technique Also proposed is a collision detection algorithm based on hierarchical data structure of subdivision surface It improves the speed of 3 D virtual garment simulation greatly The methods mentioned have been realized in a 3 D virtual garment fitting system The result shows the algorithm has the strength of high simulation, high interactive capability, and being easy to implement
