-
绘制基础图形 (HTML/SVG)
- 我们先用
<svg>标签画出两个叠在一起的圆环（<circle>）：一个作为灰色的背景，另一个作为亮黄色的进度条。 - 通过 CSS 的
stroke-dasharray和stroke-dashoffset属性，我们可以精确地控制黄色圆环显示多少，从而实现进度条功能。
- 我们先用
-
创建“水波纹”滤镜 (SVG Filter)
- 这是最关键的一步。我们在 SVG 中定义了一个
<filter>。 - 滤镜内部，首先使用
feTurbulence标签生成一张看不见的、类似云雾或大理石纹理的随机噪声图。这个噪声图本身就是动态变化的。 - 然后，使用
feDisplacementMap标签，将这张噪声图作为一张“置换地图”，应用到我们第一步画的圆环上。它会根据噪声图的明暗信息，去扭曲和移动圆环上的每一个点，于是就产生了我们看到的波纹效果。
- 这是最关键的一步。我们在 SVG 中定义了一个
-
添加交互控制 (JavaScript)
- 最后，我们用 JavaScript 监听几个 HTML 滑块（
<input type="range">）的变化。 - 当用户拖动滑块时，JS 会实时地去修改 SVG 滤镜中的各种参数，比如
feTurbulence的baseFrequency（波纹的频率）和feDisplacementMap的scale（波纹的幅度），让用户可以自由定制喜欢的效果。
- 最后，我们用 JavaScript 监听几个 HTML 滑块（
