[微信小游戏+Three.JS]给场景添加一个带贴图的3D自动旋转盒子

新建一个微信小游戏的demo后

删除没用的js，图片资源，留下下面这些，three.js和adapter.js需要简单修改，可以移步我的前一篇博客下载

直接在main.js编写代码，跟浏览器端的three.js没有什么大的区别

let THREE = require('libs/three.js')

export default class Game3d {
  constructor() {
    this.scene = new THREE.Scene();
    this.camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    this.renderer = new THREE.WebGLRenderer({
      canvas: canvas
    });
    this.start()
  }
  start() {
    this.renderer.setSize(window.innerWidth, window.innerHeight);
    var geometry = new THREE.CubeGeometry(1, 1, 1);
    var texture = new THREE.TextureLoader().load("images/Texture/muban.jpg");  
    var material = new THREE.MeshBasicMaterial({ map: texture });
    this.cube = new THREE.Mesh(geometry, material);
    this.scene.add(this.cube);
    this.camera.position.z = 2.5;
    this.cube.castShadow = true
    console.log(this.cube)
    window.requestAnimationFrame(this.loop.bind(this), canvas);
  }
  update() {
    this.cube.rotation.x += 0.02;
    this.cube.rotation.y += 0.04;
    this.cube.rotation.z += 0.06;
  }
  loop() {
    this.update()
    this.renderer.render(this.scene, this.camera);
    window.requestAnimationFrame(this.loop.bind(this), canvas);
  }
}
