[feature request] update xr-room-physics use plane detection + mesh detection #23

Open evanmcarlson opened 11 months ago

The xr-room-physics component is very helpful. It would be nice to add mesh detection (available on Quest 3) to it.

Thanks for the suggestion.

Physics for arbitrary meshes (especially non-convex ones) is hard to do in a performant way. For physics engines without CCD, it's also hard to prevent tunnelling by adding depth (as xr-room-physics does with planes).

From a quick search, I can't find much documentation explaining how non-plane meshes are exposed via the WebXR APIs.

The WebXR repo has this section on real-world geometry, which has a lot of content on XRPlanes, but very little on non-plane Meshes. Are these even supported in WebXR at this time?

Relevant WebXR standard appears to be this one.

Don't know if this is supported on Quest 3 yet.
