# MapboxGradientBuilding

> 渐变建筑，按高度插值着色的 3D 建筑。

## 简介

`MapboxGradientBuilding` 基于官方样式的 `composite/building` 渲染 3D 建筑，并按高度在 `stops` 断点间插值着色；`opacity` / `minzoom` 控制透明度与起始缩放。需倾斜视角且缩放 ≥ `minzoom`（默认 15）。

## 用法

倾斜视角下按高度对楼体分级着色：

```vue [GradientBuildingExample.vue]
<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 }"
    >
      <MapboxGradientBuilding
        :stops="[[0, '#1e3a8a'], [80, '#0ea5e9'], [200, '#f59e0b'], [400, '#f43f5e']]"
        :opacity="0.9"
      />
    </MapboxMap>
  </div>
</template>
```

## API

### Props

```ts
/**
 * Props for the MapboxGradientBuilding component
 */
interface MapboxGradientBuildingProps {
  /**
   * 图层 id；省略时自动生成
   */
  layerId?: string | undefined;
  /**
   * 高度-颜色断点
   */
  stops?: [number, string][] | undefined;
  /**
   * 整体透明度
   */
  opacity?: number | undefined;
  /**
   * 最小缩放级别
   * @default "15"
   */
  minzoom?: number | undefined;
  /**
   * 插入到该图层之前
   */
  beforeId?: string | undefined;
}
```
