| 摘 要： | 结合自主版权的超人ＣＡＤ／ＣＡＭ系统的开发，本文提出了一种适合于裁剪曲面图形显示的曲面三角化算法，该算法将曲面的三角化转化为曲面参数域的三角化，并将二维图形的集合运算与Ｄｅｌａｕｎａｙ三角剖分应有和于曲面参数域边界的处理，从而使裁剪曲面在边界上的三角形分布均匀。

| Abstract: | Combined with the development of SuperMan CAD / CAM system owned copyright,the paper presents an algorithm of triangulation of trimmed surface for the surface rendering. By converting the triangulations or surface into that of corresponding valid parametric domain, and applying the boolean operation and delaunay triangulation of 2D polygon to processing the boundary of surface parametric domain, uniform triangles bordering the boundary have been obtained. |
