检查浏览器兼容性表格要小心谨慎在生产中使用这之前。

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

This interface is accessible through the VRDisplay.stageParameters 特性。

特性

VRStageParameters.sittingToStandingTransform 只读: Contains a matrix that transforms the sitting-space view matrices of VRFrameData to standing-space.
VRStageParameters.sizeX 只读: Returns the w idth of the play-area bounds in meters.
VRStageParameters.sizeY 只读: Returns the depth of the play-area bounds in meters.

范例

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
  }
});
