Is it possible to figure out the failure reason for plane detection (via WebXRPlaneDetector and/or light estimation) in Babylon? **Why**? We want to show in app remediation prompt to user...

detectedPlanes throws exception, detection of feature availability is not graceful

1

Currently, it is possible to detect if the platform supports Plane Detection by checking the availability of `XRPlane` in `window`. Once the session has started, and the first `XRFrame` is...

Please enumerate considered alternatives in Explainers

1

The Plane Detection API explainer currently lacks a section on considered alternatives. Knowing the depth of the design thinking helps give everyone (including Blink API OWNERS) confidence in designs.

Plane detection should be promise based

From the proposal: ``` function onXRFrame(timestamp, frame) { let detectedPlanes = frame.worldInformation.detectedPlanes; detectedPlanes.forEach(plane => { let planePose = frame.getPose(plane.planeSpace, xrReferenceSpace); let planeVertices = plane.polygon; // plane.polygon is an array of...
