我有用 Three.js 创建的多边形/多面体吗？是否可以设置边框宽度和颜色？ 这是我的示例代码，您可能会在其中看到一个图。如何设置边界？ 可能还有其他方法来创建多边形？

我不确定是否 this outline effect 是您正在寻找的内容，但这是在对象周围添加边框的好方法:
<强> Here a similar question 您可以在其中找到更多示例和 working fiddle 胡闹。
如果我没记错的话，它使用了一些 WebGL 原生着色器效果，就是这一部分:
vertex_shader: [
"uniform float offset;",
"void main() {",
"vec4 pos = modelViewMatrix * vec4( position + normal * offset, 1.0 );",
"gl_Position = projectionMatrix * pos;",
"}"
].join("\n"),
