| 摘 要： | 本文提出了一种新的基于三角形移去准则的多面体模型简化方法，该方法主要由三部分组成：（１）计算与三角形相关的三角形板；（２）根据三角形移去准则判断三角形是否应删除；（３）对删除三角形后遗留的空洞进行局部三角化。本文给出的实例说明了该方法的有效性。

| Abstract: | This paper presents a new method of polyhedral model simplification based on triangle removal criterion. This method consists of three parts: (1)determine the triangle platelet incident with a triangle; (2)decide whether the triangle can be rernoved or not; (3)the holes left by the triangle removal are patched using a local optimization triangulation process. Examples illustrate efficiency of the rnethod. |
