This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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.)
This interface is accessible through the VRDisplay.getPose()
and VRDisplay.getImmediatePose()
methods.
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 occured in.
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.
Examples
TBD.
