XRWebGLBinding()

The XRWebGLBinding() constructor creates and returns a new XRWebGLBinding object.

Syntax

new XRWebGLBinding(session, context)

Parameters

session

An XRSession object specifying the WebXR session which will be rendered using the WebGL context.

context

A WebGLRenderingContext or WebGL2RenderingContext identifying the WebGL drawing context to use for rendering the scene for the specified WebXR session.

Return value

A newly-created XRWebGLBinding.

Exceptions

InvalidStateError

The new XRWebGLBinding could not be created due to one of a number of possible state errors:

• The XRSession specified by session has already been stopped.
• The specified WebGL context, context, has been lost for any reason, such as a GPU switch or reset.
• The specified session is immersive but the context is not WebXR compatible.

Example

const canvasElement = document.querySelector(".output-canvas");
const gl = canvasElement.getContext("webgl");
const xrSession = await navigator.xr.requestSession("immersive-vr");
await gl.makeXRCompatible();

const glBinding = new XRWebGLBinding(xrSession, gl);
