The updateRenderState() method of the XRSession interface of WebXR API queues an update to the active render state which will be applied on the next frame.



Parameter attributes

XRRenderState.baseLayer Read only
The XRWebGLLayer from which the User Agent's XR compositor obtains images.
XRRenderState.depthFar Read only
The distance, in meters, of the far clip plane from the viewer. A clip plane is the edge of the field of view in an AR or VR environment.
XRRenderState.depthNear Read only
The distance, in meters, of the near clip plane from the viewer. A clip plane is the edge of the field of view in an AR or VR environment.
XRRenderState.inlineVerticalFieldOfView Read only
The default vertical field of view, in radians, used when computing projection matrices. Use this value if and only if the session mode is "inline". (xr.requestSession() was called with "inline" as the mode argument.)

Return value



  • If the XR Session has already ended.
  • If the specified baseLayer is not associated with the current XR Session.
  • If inlineVerticalFieldOfView is set for the immersive experience.
Thrown in the following cases:


This example creates a WebGL context that is compatible with an immersive XR device and then uses it to create an XRWebGLLayer.

function onXRSessionStarted(xrSession) {
  let glCanvas = document.createElement("canvas");
  let gl = glCanvas.getContext("webgl", { xrCompatible: true });


  xrSession.updateRenderState({ baseLayer: new XRWebGLLayer(xrSession, gl) });
