This is a RequireJS / Browserify compatible fork of OrbitControls. See the THREE.js example for how it behaves.
This library does NOT modify the THREE object. The original OrbitControls defines this addon as "THREE.OrbitControls". This fork does not and leaves it as its own object.
var OrbitControls = require('OrbitControls.js');
var controls = new OrbitControls( camera, domElement );
Additionally, this library defines a destroy method to remove the control
bindings from the DOM element and window.
controls.destroy();
