![隐藏部分曲线、路径或边缘](https://linux22.com/image/397808/%E9%9A%90%E8%97%8F%E9%83%A8%E5%88%86%E6%9B%B2%E7%BA%BF%E3%80%81%E8%B7%AF%E5%BE%84%E6%88%96%E8%BE%B9%E7%BC%98.png)
我希望在双边经过 fl 和 hc 之间的所有地方时隐藏它(而不仅仅是在交点处)。我需要一个解决方案没有强迫我手动计算(f)和(h)处的斜率。
理想情况下,我希望能够“关闭”给定曲线两点之间的任何曲线绘制。

答案1
我发现了一个肮脏的解决方案,在节点之间绘制一个椭圆d
然后e
重新绘制它们。
