VRPose: angularVelocity property
Deprecated
Avoid using this feature in new projects. Development of the WebVR API halted in favor of WebXR. This feature may be a candidate for removal from web standards or browsers.
Consider using the following features instead: WebXR.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The angularVelocity read-only property of the VRPose interface returns an array representing the angular velocity vector of the VRDisplay at the current timestamp, in radians per second.
Note: This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
In other words, the current velocity at which the sensor is rotating around the x, y, and z axes.
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
const curFramePose = frameData.pose;
const angVel = curFramePose.angularVelocity;
const avx = angVel[0];
const avy = angVel[1];
const avz = angVel[2];
// render the scene
// …
// WebVR: submit the rendered frame to the VR display
vrDisplay.submitFrame();
}
Specifications
This property was part of the old WebVR API that has been superseded by the WebXR Device API.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. Read Meta's Porting from WebVR to WebXR guide for more information.
