Important note for THREE.js Repls [Off-topic]
THREE.Geometry deprecated with r125
In the next version of
THREE, THREE.Geometry will be removed from the three.js library.
If you use the latest version of THREE (https://threejs.org/build/three.module.js), this update will break Repls using THREE.Geometry (deprecated).
Most of the time, changing THREE.Geometry to THREE.BufferGeometry is pretty simple.
BoxGeometry are automatically switched, so those shouldn't be a problem.
