This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
The angularVelocity
read-only property of the VRPose
interface returns an array representing the angular velocity vector of the VRDisplay
at the current VRPose.timestamp
, in radians per second.
In other words, the current velocity at which the sensor is rotating around the x
, y
, and z
axes.
Syntax
var myAngularVelocity = VRPose.angularVelocity;
Value
A Float32Array
, or null
if the VR sensor is not able to provide angular velocity information.
Examples
// rendering loop for a VR scene
function drawVRScene() {
// WebVR: Request the next frame of the animation
vrSceneFrame = vrDisplay.requestAnimationFrame(drawVRScene);
// Populate frameData with the data of the next frame to display
vrDisplay.getFrameData(frameData);
// Retrieve the angular velocity values for use in rendering
// curFramePose is a VRPose object
var curFramePose = frameData.pose;
var angVel = curFramePose.angularVelocity;
var avx = angVel[0];
var avy = angVel[1];
var avz = angVel[2];
// render the scene
...
// WebVR: submit the rendered frame to the VR display
vrDisplay.submitFrame();
}
