SVG 交点设置颜色

SVG Intersection set color

所以我有一个 SVG 形状,我正在使用 GSAP 制作动画,你可以在这个 codepen here. What I want to happen is that when the lines intersect the pink circle, the inner lines turn white, like in this image:

中找到它

我试过使用 CSS 混合模式,如下所示:

line {
  mix-blend-mode: screen;
}

有什么方法可以做到这一点吗?使用 CSS 或 JavaScript?

我不了解 React,所以这可能会与您的进一步计划发生冲突,但您可以 mask 在 SVG 中解决它。您将圆 放在线条上 ,但使用 mask 移除覆盖它们的部分。然后你在粉红色圆圈后面放另一个白色圆圈,但仍在线条上方。然后通过粉色圆圈的移除部分可以看到这个圆圈,所以看起来线条好像变成了白色。

然而,这需要重组 SVG:
