# MapboxBuildingLayer

> 3D 建筑图层，挤出官方样式的 composite/building 矢量源，可调颜色、透明度与起始缩放。

## 简介

`MapboxBuildingLayer` 把 Mapbox 官方样式自带的 `composite` / `building` 矢量源挤出为 3D 建筑，封装好高度表达式，开放 `color` / `opacity` / `minzoom` 快捷设置。

> \[\!NOTE\]

> zoom
> 
> （默认 minzoom 15）才能看到建筑。

## 用法

俯仰视角下渲染城市 3D 建筑：

```vue [BuildingLayerExample.vue]
<script setup lang="ts">
// MapboxBuildingLayer 默认消费官方样式的 composite/building 矢量源
</script>

<template>
  <div class="h-115 w-full overflow-hidden rounded-(--ui-radius) border border-default">
    <MapboxMap :options="{ style: 'mapbox://styles/mapbox/light-v11', center: [116.461, 39.909], zoom: 15.5, pitch: 60, bearing: -20 }">
      <MapboxBuildingLayer color="#94a3b8" :opacity="0.85" />
    </MapboxMap>
  </div>
</template>
```

## API
