| 摘 要： | 本文在Catmull-Clark细分曲面求交完成后，采用局部修改交点处的控制网格拓扑结构和局部修正控制网格顶点位置方法，给出了控制网格上的任意点在细分曲面位置上的计算推导，方便地实现了对Catmull-Clark细分曲面的裁剪运算。

| Abstract: | When the Catmull-Clark subdivision surface intersection was be finished, the topology structure and vertices positions of control mesh at those intersection points were be modified, the position evaluation of arbitrary point on the subdivision surface was also present in this paper, the surface trimming was be realized expediently. |

| Keywords: | Catmull-Clark subdivision surface topology structure surface trimming control mesh |
