WebXR layer types, such as XRCylinderLayer, XRCylinderLayer, XREquirectLayer, XRProjectionLayer or XRQuadLayer, are managed by the system compositor, to reduce latency or resampling.

An XRHand object, from the hand attribute of an XRInputSource object, represents a WebXR session's fully-articulated hand tracking model.

The XRView.camera property provides direct access to pose-synchronized camera images within a WebXR session.

An XRDepthInformation object represents a measurement of the distance from the user's device to the real-world geometry in the user's environment.

The XRLightProbe and XRLightEstimate objects represent real-world environmental lighting conditions during a WebXR session.

The "immersive-ar" value for navigator.xr.requestSession() starts an augmented reality WebXR session that renders content aligned with the visible environment.

An XRAnchor object keeps track of a pose that is fixed relative to the real world. Anchors build an illusion that the placed objects are really present in the user's environment.

A DOM overlay shows 2D DOM content as an interactive, transparent layer on top of a WebXR application's WebGL content and camera image.

The getHitTestResults() method of an XRFrame object helps place objects in an augmented reality session by finding where cast rays intersect with real-world geometry.

The gamepad attribute of an XRInputSource represents an XR input device, such as a motion controller, that reports data from physical inputs (such as buttons, touch pads, and triggers).

The navigator.xr API represents the browser's virtual reality or augmented reality system. You can use to request a WebXR session.
