I’ve recently been playing with physics in Spark AR, and I thought I would share the journey so far. I’ve also made a project and an npm package that might help kickstart your physics exploration.

This is by no means a complete guide to physics engines, but it should be enough to get you started. For my experiments so far, I’ve been using Cannon.js.
