下面介绍在Vue.js中集成three.js的步骤。

安装vue-cli脚手架 安装three.js

npm install --save three

3.编写使用three.js创建3D场景的Vuejs组件

<template>
  <div id="container"></div>
</template>
<script>
import * as Three from 'three'

export default {
  name: 'Home',
  data () {
    return {
      camera: null,
      scene: null,
      renderer: null,
      mesh: null
    }
  },
  methods: {
    init: function () {
      var container = document.getElementById('container')

      this.camera = new Three.PerspectiveCamera(70, container.clientWidth / container.clientHeight, 0.01, 10)
      this.camera.position.z = 1

      this.scene = new Three.Scene()

      var geometry = new Three.BoxGeometry(0.2, 0.2, 0.2)
      var material = new Three.MeshNormalMaterial()

      this.mesh = new Three.Mesh(geometry, material)
      this.scene.add(this.mesh)

      this.renderer = new Three.WebGLRenderer({ antialias: true })
      this.renderer.setSize(container.clientWidth, container.clientHeight)
      container.appendChild(this.renderer.domElement)
    },
    animate: function () {
      requestAnimationFrame(this.animate)
      this.mesh.rotation.x += 0.01
      this.mesh.rotation.y += 0.02
      this.renderer.render(this.scene, this.camera)
    }
  },
  mounted () {
    this.init()
    this.animate()
  }
}

</script>
<style  rel="stylesheet/scss" lang="scss" scoped>
#container {
  width: 100%;
  height: 100%;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

</style>
