VRDisplay.getPose()

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.

The getPose() method of the VRDisplay interface returns a VRPose object defining the future predicted pose of the VRDisplay as it will be when the current frame is actually presented.

Note: This method was part of the old WebVR API. It has been superseded by the WebXR Device API.

It was evendeprecated there — instead, you should use VRDisplay.getFrameData(), which also provides a VRPose object.

Syntax

var myPose = vrDisplayInstance.getPose();

Parameters

None.

Return value

A VRPose object.

Examples

Once we have a reference to a VRDisplay object, we can retrieve the VRPose representing the current pose of the display.

if(navigator.getVRDisplays) {
  console.log('WebVR 1.1 supported');
  // Then get the displays attached to the computer
  navigator.getVRDisplays().then(function(displays) {
    // If a display is available, use it to present the scene
    if(displays.length > 0) {
      vrDisplay = displays[0];
      console.log('Display found');

          // Return the current VRPose object for the display
          var pose = vrDisplay.getPose();

          ...

    }
  });
}

It is however recommended that you use the non-deprecated pose property of the VRFrameData object (retrieved via VRDisplay.getFrameData()) to retrieve the current pose for each frame before it is submitted to the display to be presented. This happens on each iteration of the rendering loop for your app, so you can be sure the pose data is current.

Specifications

This method was part of the old WebVR API that has been superseded by the WebXR Device API.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 [1].
