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 It has been superseded by the WebXR Device API.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 current VRPose.timestamp as a 3D vector
VRPose.linearVelocity Read only: Returns the linear velocity of the VRDisplay at the current VRPose.timestamp, in meters per second.
VRPose.linearAcceleration Read only: Returns the linear acceleration of the VRDisplay at the current VRPose.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 current VRPose.timestamp, in radians per second.
VRPose.angularAcceleration Read only: Returns the angular acceleration of the VRDisplay at the current VRPose.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 when VRDisplay.getFrameData() is called — see VRFrameData.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This interface was part of the old WebVR API that has been superseded by the WebXR Device API.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].
