<yonet> https://github.com/immersive-web/proposals/issues/68

proposal #68, XRCamera capture

alcooper: Progress - needs a non-google co-sponsor

alcooper: background: Intent is to allow google model viewer to mimic what apple's model viewer does

alcooper: Meant to be a privacy preserving way to capture content, also find some way to do this on headset

alcooper: other alternatives (e.g. media streams) may not work well on headsets

Nick-8thWall: What are the use cases for headsets that would be compelling enough for a feature?

Ada: Some people want a way to do this on headsets, have some hacky ways to do it involving encoding on device. A compelling feature would be to draw from a non-viewer camera.

alcooper: Drawing from a non-viewer camera may be hard to support in existing runtimes on headsets.

cabanier: not a priority for oculus but maybe nice to have, could be more helpful in the world of passthrough

alcooper: would like to see it go forward but lower on the list of Google's current priorities

ada: straw poll for promoting to a repo vs leaving as a proposal

ada: Ok to make a repo for this, cabanier and alcooper as maintainers

cabanier: would be interesting to discuss local save + restore of anchors

<bialpio> Note: folks who look at the agenda to decide whether to join the call would miss out on this discussion.

AOB

Nick-8thWall: What's the status of anchors in WebXR

cabanier: They exist and they work well

<Zakim> atsushi, you wanted to discuss just for report, horizontal review requests are submitted for AR and gamepads module, hope to go CR around (or before) July

atsushi: Sumbitted modules for CR, hope for review around July

bajones: For api shape, may want to have a collection of anchors that are saved and restored together

bajones: theoretical fingerprinting concern?

ada: Is this any different from local storage and setting a cookie?

bajones: Need to think about this some more.

ada: Is this anchros level 2 or further work on current module? No preference.

Nick-8thWall: difference from local storage is "I'm now at a place that I was before." Need to think through what that means.
