摘要
在现有割线法基础上,提出了改进算法,直接利用Y方向切割线段修剪X方向特征轮廓,从而避免了两多边形求交的复杂耗时运算,提高了割线法的处理速度.
Based on the cutting line method discussed in previous papers the
improved method is presented. It directly uses Y cutting segments to trim X feature
contour and avoids the complex, time consuming calculation of the intersection of two simple
polygons, and then improves the speed of the cutting line method.
