This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The VRStageParameters
interface of the 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
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 } });
