Specification

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.

Risks

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 (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
