bounded-floor or unbounded - Vision OS 2.1

[antoniohof]

Hi everyone,

Has anyone managed to enter a room-scale tracking webXR scene in safari?

It always denies my request. I can't find any documentation on it in Apple or safari docs. Weirdly enough in the WWDC Apple video they explain all modes when requesting. Do you know if room scale tracking is supported?

Thanks

• A-Frame Version: 1.5.0
• Platform / Device: Vision Pro

It should work. Use A-Frame 1.6.0

[antoniohof]

It always rejects it. I'm using the xr-mode-ui and adding the flags in the web-xr attribute of the a-scene.

I wonder if it's the way xr-mode-ui requests it. I will test using a custom button and report back.

I saw this after asking on discord. We have a similar problem with the Quest 3 (s): we are having trouble using a referenceSpaceType 'unbounded' with the Meta Quest 3(s).

Using this: <a-scene xr-mode-ui="XRMode: ar" webxr="referenceSpaceType: unbounded; requiredFeatures: local-floor, unbounded; optionalFeatures: unbounded;">

We get this error: Uncaught (in promise) Error: Failed to enter AR mode (requestSession) at aframe-v1.6.0_d971f0.min.js:1:430219Caused by: NotSupportedError: The specified session configuration is not supported.

We like to avoid having/seeing the bounds (safety zone) in mixed reality mode (AR). Is this possible?

unbounded not supported by Meta Browser yet. coming soon

Probably similar for Safari Vision Pro but not 100% sure. @AdaRoseCannon any insight? thanks so much

[AdaRoseCannon]

Safari for visionOS only supports local-floor, no bounded or unbounded reference space.

Thanks @AdaRoseCannon

I leave this open as a reference but there’s nothing to do on the A-Frame side

Just digged in again and saw that this is supported when we enable WebXR experiments in the meta browser chome://flags. See: https://x.com/rcabanier/status/1813725726459535678

We will test it soon.

With Meta Quest Browser version 36.2 and onwards it should no longer be behind a flag, see: https://arvr.social/@cabanier/113789478074241825

That is right: just tested it with meta quest 3 and it works without chrome://flags! Great!

<a-scene xr-mode-ui="XRMode: xr;" webxr="requiredFeatures: hit-test,unbounded; optionalFeatures: dom-overlay,unbounded; referenceSpaceType: unbounded;" (...)

I'm not sure if we can close this issue, because it is for vision OS...
