WebGL2RenderingContext interface provides the OpenGL ES 3.0 rendering context for the drawing surface of an HTML <canvas> 元素。

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

var canvas = document.getElementById('myCanvas');
var gl = canvas.getContext('webgl2');

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.

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