@vuemap/layer-3dtiles v0.0.7

@vuemap/layer-3dtiles

简介

本项目为高德地图的3DTilesLayer图层插件，依赖@vuemap/three-layer插件，因此如果使用npm安装时需要安装@vuemap/three-layer

当前坐标只支持box、region, 不支持sphere 从0.0.7版本开始可以初始化可以不传position，不传时将默认从3dtiles数据中获取中心点和海拔

示例

模型导出时注意事项

• 当使用shp文件生成3dtiles时，参考坐标系需要根据shp文件的坐标系来设定，正常shp文件使用EPSG:4326坐标系，也就是WGS84
• 只支持box、region包围盒

开发注意事项

• 当加载3dtiles，需要关闭浏览器的开发者工具，不然在销毁3dtiles图层时会有部分显存无法释放

加载方式

当前项目支持CDN加载和npm加载两种方式。

CDN加载

CDN加载需要先加载高德地图JS、threejs的库和@vuemap/three-layer，代码如下

<!--加载高德地图JS 2.0 -->
<script src = 'https://webapi.amap.com/maps?v=2.0&key=YOUR_KEY'></script>
<!--加载threejs -->
<script src="https://cdn.jsdelivr.net/npm/three@0.143/build/three.js"></script>
<!--加载draco -->
<script src="https://cdn.jsdelivr.net/npm/three@0.143/examples/js/loaders/DRACOLoader.js"></script>
<!--加载threejs的GLTFLoader -->
<script src="https://cdn.jsdelivr.net/npm/three@0.143/examples/js/loaders/GLTFLoader.js"></script>
<!--加载three-layer插件 -->
<script src="https://cdn.jsdelivr.net/npm/@vuemap/three-layer/dist/index.js"></script>
<!--加载layer-3dtiles插件 -->
<script src="https://cdn.jsdelivr.net/npm/@vuemap/layer-3dtiles/dist/index.js"></script>

npm加载

npm加载可以直接使用安装库

npm install @vuemap/layer-3dtiles @vuemap/three-layer

使用示例

CDN方式

<script src = 'https://webapi.amap.com/maps?v=2.0&key=YOUR_KEY'></script>
<script src="https://cdn.jsdelivr.net/npm/three@0.143/build/three.js"></script>
<script src="https://cdn.jsdelivr.net/npm/three@0.143/examples/js/loaders/DRACOLoader.js"></script>
<script src="https://cdn.jsdelivr.net/npm/three@0.143/examples/js/loaders/GLTFLoader.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@vuemap/three-layer/dist/index.js"></script>
<!--加载layer-3dtiles插件 -->
<script src="https://cdn.jsdelivr.net/npm/@vuemap/layer-3dtiles/dist/index.js"></script>
<script type="text/javascript">
  const map = new AMap.Map('app', {
      center: [116.405242513021,39.909402940539],
      zoom: 14,
      viewMode: '3D',
      pitch: 35
    })
  const layer = new AMap.ThreeLayer(map)
  layer.on('complete', () => {
      const light = new THREE.AmbientLight('#ffffff', 1);
      layer.add(light);
      const tiles = new AMap.Layer3DTiles(layer, {
        url: './hutong/tileset.json',
        position: [116.405242513021,39.909402940539]
      })
      tiles.setRotation({
        x:0,
        y:0,
        z:0
      })
      tiles.setTranslate({x:15,y:15,z:0})
      tiles.on('click',(e) => {
        console.log('click: ', e)  
      })
      console.log('layer: ', layer)
      console.log('tiles: ', tiles)
  })
</script>

npm方式

import {AmbientLight} from 'three'
import {ThreeLayer} from '@vuemap/three-layer'
import {Layer3DTiles} from '@vuemap/layer-3dtiles'
const map = new AMap.Map('app', {
  center: [120,31],
  zoom: 14,
  viewMode: '3D',
  pitch: 35
})
const layer = new ThreeLayer(map)
layer.on('complete', () => {
  const light = new AmbientLight('#ffffff', 1);
  layer.add(light);
  const tiles = new Layer3DTiles(layer, {
    url: './hutong/tileset.json',
    position: [116.405242513021,39.909402940539]
  })
  tiles.setRotation({
    x:0,
    y:0,
    z:0
  })
  tiles.setTranslate({x:15,y:15,z:0})
  tiles.on('click',(e) => {
    console.log('click: ', e)
  })
  console.log('layer: ', layer)
  console.log('tiles: ', tiles)
})
