摘要
自由白面的求交算法在ＣＡＤ／ＣＡＭ软件系统中占有重要的地位，并对软件运行的效率有较大的影响。目前常用的Ｂｅｚｉｅｒ曲面分割法难以满足高精度和高速度的要求。为此该文提出了利用交线的几何信息进行快速求交的算法，同时兼顾了快速和高精度两方面的要求，并已在作者自行开发的软件中得到了成功的应用。
The algorithm of point of interaction about free surface occupies a position of importance in the CAD/CAM software system,and has a peat effect on the efficiency of running software~. The present Bezier surface segmentation is difficult to meet the demands of high precision and speed. For this reason the article advances the algorithm of point ofintersection using geometrical information of line of intersection,meanwhile it satisfied the demands^of high precision and speed,and having been applied successfully in the software developed by ourselves.
