基于Bezier曲线求交的曲线裁剪算法

CURVE CLIP ALGORITHM

本文研究了三次Ｂｅｚｉｅｒ曲线的裁剪问题。在给出了三次Ｂｅｚｉｅｒ曲线的一种求交算法后，讨论了Ｂｅｚｉｅｒ曲线在一点处的局部性质，给出了三次Ｂｅｚｉｅｒ曲线的裁剪算法。这些算法已被应用到我们自己开发的软件中，取得了良好的效果。

This paper discusses clipping between Bezier Curves . After we give a algorithm to find points of intersection between Bezier curves, We discuss curve's properties on the neighbor of a point, Then we give a clip algorithm between 3-Bezier curves. The algorithm has a very good effect.
