+主要用于绘制 3D 条形图。
+
+## 开始使用
+
+首先需要使用 [@antv/g-webgl](https://g.antv.antgroup.com/api/renderer/webgl) 作为渲染器并注册以下两个插件：
+
+- [g-plugin-3d](https://g.antv.antgroup.com/plugins/3d) 提供 3D 场景下的几何、材质和光照
+- [g-plugin-control](https://g.antv.antgroup.com/plugins/control) 提供 3D 场景下的相机交互
+
+然后设置 z 通道、scale 和 z 坐标轴，最后在场景中添加光源。
+
+```js | ob
+(() => {
+  // Create a WebGL renderer.
+  const renderer = new gWebgl.Renderer();
+  renderer.registerPlugin(new gPluginControl.Plugin());
+  renderer.registerPlugin(new gPlugin3d.Plugin());
+
+  const Chart = G2.extend(G2.Runtime, { ...G2.corelib(), ...G2.threedlib() });
+
+  // 初始化图表实例
+  const chart = new Chart({
+    renderer,
+    width: 500,
+    height: 500,
+    depth: 400,

+
+    // Add a directional light into scene.

+| ------- | --------------------------------------------- | ------------------------------ | --------- |
+| fill    | 图形的填充色                                  | `string` \| `Function<string>` | -         |
+| opacity | 图形的整体透明度                              | `number` \| `Function<number>` | -         |
