WebGLRenderingContext class

The 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 getContext() on a <canvas> element, supplying "webgl" as the argument: var canvas = document.getElementById('myCanvas'); var 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.
