Adding this work-in-progress physics sample asset. The asset needs further editing, but it is at a point where others could potentially help improve it. See the readme for details.

I had misspelled Eoin's last name, sorry Eoin!

I tried this model in the Babylon.js Playground.
Sorry if I'm using it incorrectly.
It seems to be rotating in a strange direction.

Yes, it will only work in a glTF viewer that supports the current state of these new physics extensions. Instructions for this are in the readme. As far as I know, only Eoin's fork supports this, see glTF_Physics_Babylon Viewer.

Yes, this extension is not available in Babylon.js officially yet. Hopefully, we will be working on official support for this in Babylon.js soon.

@echadwick-artist Maybe the physics extension and maybe other extensions used in this asset should be marked as required?

  "extensionsRequired": [
    "KHR_physics_rigid_bodies",
    "KHR_implicit_shapes"
  ],

Thank you for letting me know. I have confirmed that it is displayed correctly in that viewer.
