| 摘 要： | 以平面内轮廓环的存在规则和相互关系为出发点，提出了一种简单实用的轮廓环的分组算法，通过本方法对平面的轮廓环进行分组，能够把一个平面分解成一系列简单的单连通区域，分组后的轮廓环不仅能够在进行其他运算时减少重复计算，而且可以在分区填充扫描线时减少分区数，从而减少实际扫描时的空跳．

| Abstract: | A grouping algorithm for contour loops was put forward based on existing regulations and relations of contour loops. The contour loops could be transformed from multi-connectivity region into a series of single connectivity regions. The grouped contour loops could have the repeated calculation reduced when disposing contour loops and have the vacant jump decreased in the course of scanning. |

| Keywords: | rapid prototyping contour loops grouping single connectivity region multi-connectivity region |
