Terrain3D 3D 地形

three.js 实现的高程网格 3D 地形渲染。water-depth 蓝色色阶 / 陆地 elevation / 冲淤 delta 三套内置色阶；OrbitControls + 光照 + 点击拾取；three 作为 optional peerDependency 按需安装。

基础用法

传 heightData（行序展开的 number[] 或 Float32Array）+ width × height 网格尺寸。组件自动求范围、把高度映射到颜色与垂直挤压。Cesium / 复杂 GIS 平台可以输出符合这个格式的高程网格直接灌进来。

# 用 3D 组件前必须安装 three（peerDep，可选）
pnpm add three

⚠ Astro 中必须用 `client:only="vue"`

CfTerrain3D 在 mount 阶段动态 import('three') 并创建 WebGL 上下文，无法在 SSR 时执行；和 Tooltip / Modal / Toaster 一样，docs / 静态站点里嵌入演示必须用 client:only="vue"（React 端 client:only="react"），不能用 client:load。

内置色阶

色阶	适用场景
`depth`	水深 / 海底 — 深蓝→浅蓝→白
`elevation`	陆地高程 — 绿→黄褐→灰白雪线
`delta`	变化量（冲淤）— 红色下降、蓝色上升（围绕中点 0.5 反对称）
`viridis`	通用感知线性

也可以传函数 (t: number) => { r, g, b } 全自定义；t ∈ [0, 1] 按 height 归一化后传入。

API

Props

属性	类型	默认	说明
`heightData`	`number[] \| Float32Array`	—	行序展开的高程数据，长度 `width × height`
`width`	`number`	—	网格列数
`height`	`number`	—	网格行数
`bounds`	`{ minX, maxX, minY, maxY }`	—	坐标边界（可选，用于业务侧反算实际经纬度）
`minHeight` / `maxHeight`	`number`	自动	强制色阶上下限；不传时从数据求 min/max
`exaggeration`	`number`	`1`	垂直夸张倍数
`colorScale`	`'depth' \| 'elevation' \| 'delta' \| 'viridis' \| Fn`	`'depth'`	内置色阶或自定义函数
`wireframe`	`boolean`	`false`	叠加线框
`camera`	`{ pitch?, yaw?, zoom? }`	—	初始相机角度（degrees）与距离倍数
`autoRotate`	`boolean`	`false`	自动绕场景旋转
`showGrid`	`boolean`	`false`	底部网格辅助
`background`	`string`	`oklch(13%)`	canvas 容器背景色
`rendererWidth` / `rendererHeight`	`number \| string`	`100% × 480`	容器尺寸

Events

事件	载荷	说明
`ready`	—	渲染器就绪
`pick`	`{ x, y, z, row, col }`	点击地形拾取，坐标 + 网格行列

与 Cesium / Mapbox GL 的关系

Cesium: 完整地球级 GIS 平台（瓦片 / 地形 / 影像 / 时间轴 / 坐标变换），bundle ~10 MB。适合做完整 GIS 应用。
CfTerrain3D: 单一关注「一块高程网格的 3D 可视化」，不做地图投影 / 瓦片 / 时间轴，~60 KB（不含 three peerDep）。适合做仪表盘里的水深 / 冲淤 / DEM 单卡视图。

需要完整 Cesium 集成请直接 npm i cesium 自用；CfTerrain3D 只在你已有 height 网格数据时用。
