WebGL2RenderingContext

Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨September 2021⁩.

* Some parts of this feature may have varying levels of support.

Note: This feature is available in Web Workers.

The WebGL2RenderingContext interface provides the OpenGL ES 3.0 rendering context for the drawing surface of an HTML <canvas> element.

To get an object of this interface, call getContext() on a <canvas> element, supplying "webgl2" as the argument:

const canvas = document.getElementById("myCanvas");
const gl = canvas.getContext("webgl2");

Note: WebGL 2 is an extension to WebGL 1. The WebGL2RenderingContext interface implements all members of the WebGLRenderingContext interface. Some methods of the WebGL 1 context can accept additional values when used in a WebGL 2 context. You will find this info noted on the WebGL 1 reference pages.

The WebGL tutorial has more information, examples, and resources on how to get started with WebGL.
