VRPose
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The VRPose
interface of the WebVR API represents the state of a VR sensor at a given timestamp (which includes orientation, position, velocity, and acceleration information.)
Note: This interface was part of the old WebVR API. It has been superseded by the WebXR Device API.
This interface is accessible through the VRDisplay.getPose()
and VRDisplay.getFrameData()
methods. VRDisplay.getPose()
is deprecated.
Properties
VRPose.position
Read only-
Returns the position of the
VRDisplay
at the currentVRPose.timestamp
as a 3D vector VRPose.linearVelocity
Read only-
Returns the linear velocity of the
VRDisplay
at the currentVRPose.timestamp
, in meters per second. VRPose.linearAcceleration
Read only-
Returns the linear acceleration of the
VRDisplay
at the currentVRPose.timestamp
, in meters per second per second. VRPose.orientation
Read only-
Returns the orientation of the sensor at the current
VRPose.timestamp
, as a quarternion value. VRPose.angularVelocity
Read only-
Returns the angular velocity of the
VRDisplay
at the currentVRPose.timestamp
, in radians per second. VRPose.angularAcceleration
Read only-
Returns the angular acceleration of the
VRDisplay
at the currentVRPose.timestamp
, in meters per second per second.
Obsolete properties
VRPose.timeStamp
Read only-
Returns the current time stamp of the system — a monotonically increasing value useful for determining if position data has been updated, and what order updates have occurred in. This version of
timestamp
has been removed from the spec — instead, timestamps are now returned whenVRDisplay.getFrameData()
is called — seeVRFrameData.timestamp
.
Examples
See VRDisplay.getFrameData()
for example code.
Specifications
This interface was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.
Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
