I have the following fiddle, where you can move a cube using the arrow keys: Three.js base - JSFiddle - Code Playground The goal is that you can move the cube on the grey plane but when you move it outside is should drop off.

place the physics in a worker so it process independently with three.js thread, this method u have smooth rendering unaffected by physics process.
