摘　　要：介绍了在使用参数化方法建立曲面的初始网格之后,再对初始网格进行LOOP细分的过程,以虚拟织物在悬垂仪上的悬垂效果.在LOOP细分的实现过程中,运用简便易于实现的OAVL数据结构,可以很方便地取得网格中邻近点、边、面的相关信息.最后给出了2个悬垂形态模拟的例子.The process of Loop subdivision of the original mesh established by parameterized method was introduced, and the draping model of fabrics was simulated. In the procedure of Loop subdivision, OAVL structure was proposed for the convenient implementation of subdivision. Through OAVL structure, all the factors and their relationships in a mesh can be found easily. Finally two examples of draping models were given.
