Bullet Physics 3 server for node.js. Designed for multiple realtime clients.
Runs at native C++ speed in a dedicated process, so this is probably the fastest physics you can get for node. This is not an emscripten build, and does not run in the browser. If that's what you want, you're probably looking for ammo.js.
This also does not include any rendering, only the backend number crunching. If you want rendering, you probably want to plug this into a THREE.js frontend.
