手把手教你在vue中使用three.js

npm install three

//import * as THREE from 'three' 
import * as Three from 'three'  

const scene = new THREE.Scene()

const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000)

camera.position.set(0, 0, 10)

scene.add(camera)

const Geometry = new THREE.BoxGeometry(1, 1, 1)

// 几何体材质
const texture = new THREE.MeshBasicMaterial({
  color: 0xffff
})

// 将几何体和材质创建成物体
const mesh = new THREE.Mesh(Geometry, texture)
// 将几何体添加到场景中
scene.add(mesh)

// 设置渲染器的大小
render.setSize(window.innerWidth, window.innerHeight)

// 将渲染器添加到页面 将webGL渲染的canves添加到body
document.body.appendChild(render.domElement)

import * as Three from 'three'
// 导入轨道控制器

      let material = new Three.MeshBasicMaterial({map: a });

      // 渲染器的大小
