How to create polygon body cannonjs of a 3d model using cannonjs

im it is not possible. you can approximate with a box or spherical shape but a convex hull or even trimesh will kill it. i've not seen it run even the most basic convex shapes with reasonable performance. you should probably look towards rapier.

#

and if that's an option, i don't think there's an easier way to physics than rt/rapier https://codesandbox.io/s/rapier-physics-7e9y1b you can literally just wrap your model or whole scene into a rigidbody and it just works
