问题描述

我想要一个擦拭动画看起来像水滴在一滴内。它目前是一个正方形，在下降标志的顶部有一个波浪动画。它正确地完成了波浪动画，但我不能让它留在掉落中并且也填满。

I am to get a wipe animation to look like water is filling up inside of a drop. It currently is a square with a wave animation over top of the drop logo. It does the wave animation correctly but I can't get it to stay inside the drop and also fill up.

我越来越接近但我仍然需要实际的徽标至少在圈内。

I'm getting closer but I still need the actual logo to be inside the circle at least.

我的进步：

推荐答案

以下内容将您的代码修改为：

The following modifies your code to:


  • 删除视口（我发现使用转换更容易，

  • 制作drop和h字母的副本，

  • 将副本合并到一个路径中，

  • 将路径合并到< clipPath> 元素在< svg> 中的< defs> 元素内，并为其指定一个ID（drop ）

  • 在< g class =fill>周围放置一个封闭的< g> 元素; group，

  • 使用drop封闭< g> 元素的剪辑，以及

  • 缩放并将黑边界的drop-and-h以及剪辑路径drop-and-h翻译相同的数量，以便它们以wavehape为中心。

  • remove the viewport (I just find it easier to use transform),
  • make a copy of both the drop and the "h" letter,
  • merge the copies into a single path,
  • place that merged path inside a <clipPath> element inside a <defs> element in the <svg> and give it an id ("drop")
  • place an enclosing <g> element around the <g class="fill"> group,
  • clip that enclosing <g> element using the "drop", and
  • scale and translate both the black-bordered drop-and-h as well as the clip path drop-and-h by the same amounts so that they are centered on the waveshape.

您可以阅读 MDN上的clipPath 。

顺便说一下，请注意你的波形动画可能会永远持续下去，即使你不能再看到波浪晃动（虽然我没有严格检查），这可能不是你想要的。

By the way, note that your wave shape animation may continue forever even if you can't see the waves sloshing around any more (though I didn't check this rigorously), which is probably not what you want.
