OrbitControls with ES6 modules (2019 Bastien Robert edit)
Simple example : https://codesandbox.io/s/lyz5y4kq0z
Import like import OrbitControls from './OrbitControls' then use it like in the THREEJS doc but create your controls like this: const controls = new OrbitControls()
Because it prevents the following error: Attempted import error: 'OrbitControls' is not exported from 'three' (imported as 'THREE').
| // Most of this code has been copied and pasted from the ThreeJS documentation | |
| // https://threejs.org/docs/index.html#manual/en/introduction/Creating-a-scene | |
| import * as THREE from 'three'; | |
| import OrbitControls from './OrbitControls'; | |
| var scene = new THREE.Scene(); | |
