Specification
https://immersive-web.github.io/plane-detection


Summary
The WebXR Plane Detection API allows sites to retrieve the set of planes 
detected in the user's environment. This is both less work for developers and 
more powerful than using the depth-sensing WebXR feature as planes such as 
walls that are occluded by objects can still be fully represented if the system 
is aware of the boundaries of the wall. (Whereas a depth map would show the 
wall, but it would be broken up by any objects in front of the wall, 
potentially obscuring the full scope of the wall). Further, semantic labeling 
information is exposed where the device is aware of such labels and they fit 
into predefined categories, allowing better knowledge about the world.

Interoperability and Compatibility
No information provided

Gecko: Defer (https://github.com/mozilla/standards-positions/issues/1346) 
Presumptive Defer due to that being the state of all other WebXR positions due 
to current lack of support/development.

WebKit: No signal (https://github.com/WebKit/standards-positions/issues/608)

Web developers: Positive

Other signals:


WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it 
has potentially high risk for Android WebView-based applications?
No information provided



Debuggability
No information provided


Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, 
ChromeOS, Android, and Android WebView)?
No
WebXR itself is only support on Android and Windows, and not on Android 
WebView. This will be supported on all platforms, but primary usage is expected 
to be on Android.


Is this feature fully tested by web-platform-tests?
Yes

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop 
issues. Please list open issues (eg links to known github issues in the project 
for the feature specification) whose resolution may introduce web 
compat/interop risk (eg, changing to naming or structure of the API in a 
non-backward-compatible way).
