This piece of code is currently functioning correctly, except for one issue - the lack of animation. The code draws an axis and a cube, but the cube should be animated. I only see the "animate" string in the console once.
Solution: Replace this line
requestAnimationFrame(() => this.animate);requestAnimationFrame(this.animate.bind(this));/// <reference path="../node_modules/@types/three/index.d.ts" />
//import * as THREE from "three";
// this line does't work. Error: Cannot find module 'three' from ...
