The cancelAnimationFrame() method of the VRDisplay interface is a special implementation of Window.cancelAnimationFrame that unregisters callbacks registered with VRDisplay.requestAnimationFrame().
The capabilities read-only property of the VRDisplay interface returns a VRDisplayCapabilities object that indicates the various capabilities of the VRDisplay.
The depthFar property of the VRDisplay interface gets and sets the z-depth defining the far plane of the eye view frustum, i.e. the furthest viewable boundary of the scene.
The depthNear property of the VRDisplay interface gets and sets the z-depth defining the near plane of the eye view frustum, i.e. the nearest viewable boundary of the scene.
The exitPresent() method of the VRDisplay interface stops the VRDisplay presenting a scene.
The getEyeParameters() method of the VRDisplay interface returns the VREyeParameters object containing the eye parameters for the specified eye.
The getImmediatePose() method of the VRDisplay interface returns a VRPose object defining the current pose of the VRDisplay, with no prediction applied.
The getLayers() method of the VRDisplay interface returns the layers currently being presented by the VRDisplay.
The getPose() method of the VRDisplay interface returns a VRPose object defining the future predicted pose of the VRDisplay as it will be when the current frame is actually presented.
The isConnected read-only property of the VRDisplay interface returns a Boolean indicating whether the VRDisplay is connected to the computer.
The isPresenting read-only property of the VRDisplay interface returns a Boolean indicating whether the VRDisplay is currently having content presented through it.
The requestAnimationFrame() method of the VRDisplay interface is a special implementation of Window.requestAnimationFrame containing a callback function that will be called every time a new frame of the VRDisplay presentation is rendered:
The resetPose() method of the VRDisplay interface resets the pose for the VRDisplay, treating its current VRPose.position and VRPose.orientation as the "origin/zero" values.
The stageParameters read-only property of the VRDisplay interface returns a VRStageParameters object containing room-scale parameters, if the VRDisplay is capable of supporting room-scale experiences.
The submitFrame() method of the VRDisplay interface captures the current state of the VRLayer currently being presented and displays it on the VRDisplay.
The VRDisplayCapabilities interface of the WebVR API describes the capabilities of a VRDisplay — its features can be used to perform VR device capability tests, for example can it return position information.
The canPresent read-only property of the VRDisplayCapabilities interface returns a Boolean stating whether the VR display is capable of presenting content (e.g. through an HMD).
The hasExternalDisplay read-only property of the VRDisplayCapabilities interface returns a Boolean stating whether the VR display is separate from the device's primary display.
The hasOrientation read-only property of the VRDisplayCapabilities interface returns a Boolean stating whether the VR display can track and return orientation information.
