Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

简介

本项目为高德地图的threejs图层插件,包含ThreeLayer图层、ThreeGltf加载

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和threejs的库,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/[email protected]/build/three.js"></script>
<!--加载threejs的GLTFLoader -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/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>

npm加载

npm加载可以直接使用安装库

npm install '@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/[email protected]/build/three.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/examples/js/loaders/GLTFLoader.js"></script>

<script src="https://cdn.jsdelivr.net/npm/@vuemap/three-layer/dist/index.js"></script>
<script type="text/javascript">
  const map = new AMap.Map('app', {
      center: [120,31],
      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 gltf = new AMap.ThreeGltf(layer, {
          url: 'https://a.amap.com/jsapi_demos/static/gltf/Duck.gltf',
          configLoader: (loader) =>{
              const dracoLoader = new THREE.DRACOLoader()
              dracoLoader.setDecoderPath('https://cdn.jsdelivr.net/npm/[email protected]/examples/js/libs/draco/');
              loader.setDRACOLoader( dracoLoader );
          },
          position: [120, 31],
          scale: 800,
          rotation: {
              x:90,
              y:0,
              z:0
          }
      })
      console.log('layer: ', layer)
      console.log('gltf: ', gltf)
  })
</script>

npm方式

import {AmbientLight} from 'three'
import {ThreeLayer, ThreeGltf} from '@vuemap/three-layer'
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 gltf = new ThreeGltf(layer, {
    url: 'https://a.amap.com/jsapi_demos/static/gltf/Duck.gltf',
    position: [120, 31],
    scale: 800,
    rotation: {
      x:90,
      y:0,
      z:0
    }
  })
  console.log('layer: ', layer)
  console.log('gltf: ', gltf)
})
