XRViewerPose extension type
The WebXR Device API interface XRViewerPose
represents the pose (the
position and orientation) of a viewer's point of view on the scene. Each
XRViewerPose
can have multiple views to represent, for example, the slight
separation between the left and right eye.
This view can represent anything from the point-of-view of a user's XR headset to the viewpoint represented by a player's movement of an avatar using mouse and keyboard, presented on the screen, to a virtual camera capturing the scene for a spectator.

The
emulatedPosition
read-only attribute of the XRPose interface is a Boolean value indicating whether or not both the XRRigidTransform.position component of the pose's XRPose.transform is directly taken from the XR device, or it's simulated or computed based on other sources.no setterinherited - hashCode → int
-
The hash code for this object.

JSObject> -
The read-only XRViewerPose property
views
returns an array which contains everyXRView
which must be rendered in order to fully represent the scene from the viewpoint defined by the viewer pose. For monoscopic devices, this array contains a single view.no setter
