VRPose: angularAcceleration property

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.

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 angularAcceleration read-only property of the VRPose interface returns an array representing the angular acceleration vector of the VRDisplay at the current timestamp, in meters per second 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 It has been superseded by the WebXR Device API.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 acceleration of the sensor's rotation around the x, y, and z axes.

Value

A Float32Array, or null if the VR sensor is not able to provide angular acceleration information.

Examples

js
// 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 acceleration values for use in rendering
  // curFramePose is a VRPose object
  const curFramePose = frameData.pose;
  const angAcc = curFramePose.angularAcceleration;
  const aax = angAcc[0];
  const aay = angAcc[1];
  const aaz = angAcc[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This property was part of the old WebVR API that has been superseded by the WebXR Device API.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.
