require('aframe');
require('aframe-potree-loader-component');This is basically just a wrapper around PIX4D's three-potree-loader package. They did all the hard work (and saved myself lots of time) of extracting the core loading and rendering functionality of the Potree point cloud viewer. That's the spirit of open-source. We all build up on each other and adapt to certain needs, in that case point clouds within WebVR.
