stats性能插件添加了以后，会默认在左上角显示性能帧数，每次刷新所用时间，占用内存。鼠标左键点击可进行切换，默认显示每秒的帧数。
案例查看地址：http://www.wjceo.com/blog/threejs/2018-02-09/11.html
首先需要将stats插件引入，地址是官网下载文件里面的examples/js/libs/stats.min.js。
然后需要实例化一个组件，然后添加到dom当中。
//初始化性能插件var stats;function initStats() {stats = new Stats();document.body.appendChild(stats.dom);}function animate() {//更新控制器controls.update();render();//更新性能插件stats.update();requestAnimationFrame(animate);}就这样，页面当中就会显示出来正常插件效果了。
设置默认显示的监听。
Stats.prototype.setMode()方法可以设置插件的默认监听
stats.setMode(0); //默认的监听fps
stats.setMode(1); //默认的监听画面渲染时间
stats.setMode(2); //默认的监听当前的不知道是啥案例也是用的上一节的案例写的，全部代码：
