WebGL: 2D and 3D graphics for the web
Note: This feature is available in Web Workers.
WebGL (Web Graphics Library) is a JavaScript API for rendering high-performance interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins. WebGL does so by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML <canvas> elements. This conformance makes it possible for the API to take advantage of hardware graphics acceleration provided by the user's device.
Support for WebGL is present in all modern browsers (see the compatibility tables below); however, the user's device must also have hardware that supports these features.
The WebGL 2 API introduces support for much of the OpenGL ES 3.0 feature set; it's provided through the WebGL2RenderingContext interface.
The <canvas> element is also used by the Canvas API to do 2D graphics on web pages.
