After understanding the concept of line clipping, let us now learn something more advanced. In this chapter, we will show how to clip some shape or a polygon. One of the most widely used algorithms for polygon clipping is the Sutherland-Hodgman Algorithm. This algorithm handles the clipping ...
Line clipping against a polygon is widely used in computer graphics such as the hidden line problem. A newline-clipping algorithm against a general polygon is presented in this paper. The basic idea of this algorithm is tochange the line to be clipped into a horizontal line by shearing ...

The Martinez-Rueda-Feito polygon clipping algorithm is used to compute the result inO((n+k)*log(n))time, wherenis the total number of edges in all polygons involved andkis the number of intersections between edges. Settings Global settings are set via environment variables. ...
F. Martinez paper另一个关键观点是的,如果我们使用它Bentley-Ottmann algorithm检测线之间的交叉点,然后我们可以利用同时,计算线段填写注释 这是一个非常聪明的观察……但这意味着我们需要使我们的交叉检测相当复杂. 使用该技术的另一个优点是,它比依次测试每个边缘快得多,特别是随着线段数的增加. ...
