You're right, it turns out to be a gradient descent function adapted from numeric.js. Seems like a long way to go to interpolate mouse events into a range of values. Still suffers from gimbal lock in the cube demo. I guess since it doesn't allow you to manage the draw routine, you couldn't use quaternion to Euler conversion. I'm not sure I see the purpose of it. But what do I know, I don't have a stem degree.
