I don&#x27;t have a use for this, but I do have a friendly piece of advice: I saw a demo of a molecule manipulator for the Leap Motion (which I have) and it was an <i>amazingly</i> intuitive way to manipulate 3D models. The Leap JS API is very simple to use (they really give you everything you need) and you can probably integrate it in an hour. I definitely recommend adding Leap support, it&#x27;s a fantastic way to zoom and pan your model around with natural gestures.
