https://xboxdesignlab.xbox.com/en-US/customize/bumpers-triggers do you think that a similar solution can be prototyped with Framer? Any ideas and comments are welcome.
http://www.babylonjs.com/ is used webgl based components...here is the github link, somebody can find that interesting: https://github.com/BabylonJS/Babylon.js
The UI: yes. But Framer does not have 3d rendering build in other than very basic panes. For this I would combine Framer with Babylon or Three.js to render the controller.
