这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

angularAcceleration 只读特性在 VRPose interface returns an array representing the angular acceleration vector of the VRDisplay 在当前 VRPose.timestamp , in meters per second per second.

In other words, the current acceleration of the sensor's rotation around the x , y ，和 z axes.

句法

var myAngularAcceleration = VRPose.angularAcceleration;
					

值

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

范例

// 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
  var curFramePose = frameData.pose;
  var angAcc = curFramePose.angularAcceleration;
  var aax = angAcc[0];
  var aay = angAcc[1];
  var aaz = angAcc[2];
  // render the scene
  ...
  // WebVR: submit the rendered frame to the VR display
  vrDisplay.submitFrame();
}
