WebGLRenderingContext | WebGL2RenderingContext

WebGLRenderingContext and WebGL2RenderingContext are the JavaScript(?) interfaces for the OpenGL ES graphics rendering context. They allow to draw onto the surface of a <canvas> HTML element.

A WebGLRenderingContext or WebGL2RenderingContext object can be obtained by calling HTMLCanvasElement.getContext with the parameter value webgl or webgl2.
