| 摘 要： | 鉴于FDM/SLA快速成形中实现支撑自动生成的关键是实现复杂轮廓层之间的布尔运算，提出将复杂的轮廓层之间的布尔运算分解成带有孔洞的多边形之间的布尔运算．提出了一种基于线段和带有孔洞的多边形之间关系的布尔运算算法，并重点讨论了点重合和边重合的特殊情况．

| Abstract: | A method for dividing a complex sectional contour into several polygons with holes. Was introduced. Then this problem turned to realization of Boolean operation between the two polygons with holes. A method of Boolean operation for polygons with holes based on the relation between line and polygon with holes was proposed. The specific processing method on how to deal with point overlap and edge overlap was provided. |
