| 摘 要： | 本文提出了一种新的曲面求交方法,这种方法基于曲面控制网格的“子”分方法,只要控制网格足够逼近曲面,则通过对控制网格处理一系列特殊的直线与三角形求交问题,就可迅速、逼近地求出两张双三次曲面片的交线。

| Abstract: | In this paper,a new method for fast finding intersection of two bicubic surface patches is de- scribed.Based on subdivision algorithm,two control polygons are first made to approximate the surfaces with arbitrary precision,then the curve of intersection can be fast found by a series of triangles and lines defined in a particular way. |
