VRStageParameters

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 VRStageParameters interface of the WebVR API represents the values describing the stage area for devices that support room-scale experiences.

This interface is accessible through the VRDisplay.stageParameters property.

Properties

VRStageParameters.sittingToStandingTransform Read only
Contains a matrix that transforms the sitting-space view matrices of VRFrameData to standing-space.
VRStageParameters.sizeX Read only
Returns the width of the play-area bounds in meters.
VRStageParameters.sizeY Read only
Returns the depth of the play-area bounds in meters.

Examples

var info = document.querySelector('p');
var vrDisplay;

navigator.getVRDisplays().then(function(displays) {
  vrDisplay = displays[0];
  var stageParams = vrDisplay.stageParameters;
  // stageParams is a VRStageParameters object

  if(stageParams === null) {
    info.textContent = 'Your VR Hardware does not support room-scale experiences.'
  } else {
    info.innerHTML = '<strong>Display stage parameters</strong>'
                 + '<br>Sitting to standing transform: ' + stageParams.sittingToStandingTransform
                 + '<br>Play area width (m): ' + stageParams.sizeX
                 + '<br>Play area depth (m): ' + stageParams.sizeY
  }
});
