There is a physics engine for threejs- it's somewhere on their demo page. I'm actually working on a physics engine as well- I'm willing to help you extend it in whatever direction.

A question, Why did you chose Verlet integration? I know it's great for particles but I always had issues trying to do angular mechanics.

Are you thinking of Physijs [0], which is made to work well with ThreeJS? Its a wrapper around Ammojs for ThreeJS.

It does look good and integrates well, but to be honest ThreeJS is so mature and battle tested with multiple renderers (canvas, webgl etc) that when building a physics engine, I really think it would be better to spend ones dev time on the physics and not waste* time reimplementing a portion of ThreeJS.

*Obviously not actually 'wasted' time, hacking is great even just for the sake of it - but I'm sure you know what I mean.

Great question- I was reading about verlet integration and started doing some coding to play with it, and I just kept on going with it. Would love some help with it! First thing I would like to do is abstract out canvas.
