ANGLE (Almost Native Graphics Layer Engine) is an open source zlib licensed graphics engine abstraction layer developed by Google. The API is mainly designed to bring high performance OpenGL compatibility to Windows desktops and to Web Browsers such as Google Chromium. It is currently used by a host of software including Qt Framework.
The project started as a way for Google to bring full hardware acceleration for WebGL to Windows without relying on OpenGL graphics device drivers. Google initially released the program under the BSD license.
