+# PixelPickingEngine 设计
+
+在地图交互中，除了地图底图本身提供的平移、旋转、缩放、flyTo 等相机动作，最常用的就是信息要素的拾取以及后续的高亮了。
+
+3D 引擎常用的拾取技术通常有两种：RayPicking 和 PixelPicking。前者从鼠标点击处沿着投影方向发射一根射线，通过包围盒碰撞检测获取到接触到的第一个对象，后续就可以进行选中对象的高亮甚至是跟随移动了，以上运算均在 CPU 侧完成。
+但是在 L7 的场景中，海量数据在同一个 Geometry 中，无法计算每个要素的包围盒，因此在 GPU 侧完成的 PixelPicking 更加适合。
+
+作为拾取引擎 PixelPickingEngine，除了实现内置基本的拾取 Pass，最重要的是提供友好易用的 API，覆盖以下常见场景：
+* 基本的拾取场景，用户只需要开启 Layer 拾取功能并设置高亮颜色即可。
+* 拾取后展示特定 UI 组件的场景，用户需要监听事件，在回调中使用上述拾取对象完成组件展示。
+* 更灵活的联动场景，用户可以不依赖 L7 内置的事件监听机制，直接拾取并高亮指定点/区域包含的要素。
+
+本文会依次介绍：
+* PixelPicking 原理
+* 使用方法
+    * 拾取对象结构
+    * 拾取 API 的使用方法
+        * 开启/关闭拾取
+        * 设置高亮颜色
+        * 展示自定义 UI 组件
+    * 在自定义 Layer 中使用
+
+## PixelPicking 原理
+
+在执行时机方面，基于 [MultiPassRenderer](./MultiPassRenderer.md) 的设计，拾取发生在实际渲染之前：
+```
+ClearPass -> PixelPickingPass -> RenderPass -> [ ...其他后处理 Pass ] -> CopyPass
+```
+
+PixelPickingPass 分解步骤如下：
+1. 逐要素编码（idx -> color），传入 attributes 渲染 Layer 到纹理。
+2. 获取鼠标在视口中的位置。由于目前 L7 与地图结合的方案为双 Canvas 而非共享 WebGL Context，事件监听注册在地图底图上。
+3. 读取纹理在指定位置的颜色，进行解码（color -> idx)，查找对应要素，作为 Layer `onHover/onClick` 回调参数传入。
+4. （可选）将待高亮要素对应的颜色传入 Vertex Shader 用于每个 Vertex 判断自身是否被选中，如果被选中，在 Fragment Shader 中将高亮颜色与计算颜色混合。
+
+## 使用方法
+
+### 拾取对象结构定义
+
+拾取对象结构定义如下：
+
+| 参数名 | 类型 | 说明 |
+| -------- | --- | ------------- |
+| x | `number` | 鼠标位置在视口空间 x 坐标，取值范围 `[0, viewportWidth]` |
+| y | `number` | 鼠标位置在视口空间 y 坐标，取值范围 `[0, viewportHeight]` |
+| lnglat | `{ lng: number; lat: number; }` | 鼠标位置经纬度坐标 |
+| feature | `object` | GeoJSON feature 属性 |
+
+### API
+
+对于基本的拾取场景，用户只需要开启 Layer 拾取功能并设置高亮颜色即可。
+而对于拾取后展示特定 UI 组件的场景，用户需要监听事件，在回调中使用上述拾取对象完成组件展示。
+最后，对于更灵活的联动场景，用户可以不依赖 L7 内置的事件监听机制，直接拾取并高亮指定点/区域包含的要素。
+
+#### 禁用/开启拾取
+
+并不是所有 Layer 都需要拾取（例如文本渲染 Layer），通过 `enablePicking` 关闭可以跳过该阶段，减少不必要的渲染开销：
+```typescript
+const layer = new PolygonLayer({
+    enablePicking: false, // 关闭拾取
+});
+```
+
+⚠️L7 默认开启拾取。
+
+#### 设置高亮颜色
+
+如果一个 Layer 开启了拾取，我们可以通过 `highlightColor` 设置高亮颜色：
+```typescript
+const layer = new PolygonLayer({
+    enablePicking: true, // 开启拾取
+    highlightColor: 'red', // 设置高亮颜色
+});
+```
+
+#### 展示自定义 UI 组件
+
+监听 Layer 上的 `hover/mousemove` 事件就可以得到拾取对象，然后通过对象中包含的位置以及原始数据信息，就可以使用 L7 内置或者自定义 UI 组件展示：
+```typescript
+layer.on('hover', ({ x, y, lnglat, feature }) => {
+    // 展示 UI 组件
+});
+layer.on('mousemove', ({ x, y, lnglat, feature }) => {
+    // 同上
+});
+```
+
+除了基于事件监听，还可以通过 Layer 的构造函数传入 `onHover` 回调，在后续 Layer 对应的 react 组件中也可以以这种方式使用：
+```typescript
+const layer = new PolygonLayer({
+    enablePicking: true,
+    onHover: ({ x, y, lnglat, feature }) => {
+        // 展示 UI 组件
+    },
+});
+```
+
+#### 直接调用拾取引擎方法
+
+除了默认在地图上交互完成拾取，在与其他系统进行联动时，脱离了地图交互，仍需要具备拾取指定点/区域内包含要素的能力。
+```typescript
+anotherSystem.on('hover', ({ x, y }) => {
+    layer.pick({
+        x,
+        y,
+    });
+});
+```
+
+⚠️目前只支持拾取视口中一个点所在的要素，未来可以实现拾取指定区域内的全部要素。
+
+### 自定义 Layer 中的拾取
+
+用户实现自定义 Layer 时，必然需要实现 Vertex/Fragment Shader。如果也想使用拾取功能，就需要在 Shader 中引入拾取模块，方法如下。
+
+在 Vertex Shader 中引入 `picking` 模块。关于 L7 Shader 的模块化设计，[详见]()。
+```glsl
+// mylayer.vert.glsl
+
+#pragma include "picking"
+
+void main() {
+  setPickingColor(customPickingColors);
+}
+```
+
+在 Fragment Shader 中
+```glsl
+// mylayer.frag.glsl
+
+#pragma include "picking"
+
+void main() {
+  // 必须在末尾，保证后续不会再对 gl_FragColor 进行修改
+  gl_FragColor = highlightPickingColor(gl_FragColor);
+}
+```
+
+其中涉及 `picking` 模块方法说明如下：
+
+| 方法名 | 应用 shader | 说明 |
+| -------- | --- | ------------- |
+| `setPickingColor` | `vertex` | 比较自身颜色编码与高亮颜色，判断是否被选中，传递结果给 fragment |
+| `highlightPickingColor` | `fragment` | 当前 fragment 被选中则使用高亮颜色混合，否则直接输出原始计算结果 |
