WebGLRenderingContext extension type

The WebGLRenderingContext interface provides an interface to the OpenGL ES 2.0 graphics rendering context for the drawing surface of an HTML canvas element.

To get an access to a WebGL context for 2D and/or 3D graphics rendering, call HTMLCanvasElement.getContext on a <canvas> element, supplying "webgl" as the argument:

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

Once you have the WebGL rendering context for a canvas, you can render within it. The WebGL tutorial has more information, examples, and resources on how to get started with WebGL.

If you require a WebGL 2.0 context, see WebGL2RenderingContext; this supplies access to an implementation of OpenGL ES 3.0 graphics.

Properties

canvas → JSObject
The WebGLRenderingContext.canvas property is a read-only reference to the HTMLCanvasElement or OffscreenCanvas object that is associated with the context. It might be null if it is not associated with a canvas element or an OffscreenCanvas object.
no setter
drawingBufferColorSpace ↔ PredefinedColorSpace
The WebGLRenderingContext.drawingBufferColorSpace property specifies the color space of the WebGL drawing buffer. Along with the default (srgb), the display-p3 color space can be used.
getter/setter pair
