# MapboxWindowBuilding

> 窗户建筑，程序生成窗户点阵贴图作 fill-extrusion-pattern。

## 简介

`MapboxWindowBuilding` 基于官方样式的 `composite/building` 渲染 3D 建筑，并用程序生成的窗户点阵贴图作 `fill-extrusion-pattern`；`rows` / `cols` / `litColor` / `darkColor` / `litRatio` / `seed` 控制窗格外观。需倾斜视角且缩放 ≥ `minzoom`（默认 15）。

## 用法

夜色样式下点亮随机窗格：

```vue [WindowBuildingExample.vue]
<template>
  <div class="h-115 w-full overflow-hidden rounded-(--ui-radius) border border-default">
    <MapboxMap
      :options="{ style: 'mapbox://styles/mapbox/dark-v11', center: [116.461, 39.909], zoom: 15.5, pitch: 60, bearing: -20 }"
    >
      <MapboxWindowBuilding :rows="10" :cols="6" lit-color="#fde68a" dark-color="#1f2937" :lit-ratio="0.45" />
    </MapboxMap>
  </div>
</template>
```
