ANGLE (Almost Native Graphics Layer Engine) is an open source, BSD-licensed graphics engine abstraction layer developed by Google. The API is mainly designed to bring high-performance OpenGL compatibility to Windows computers and to web browsers such as Chromium by translating OpenGL calls to Direct3D, which has much better driver support. There are two backend renderers for ANGLE: the oldest one uses Direct3D 9.0c, while the newer one uses Direct3D 11.
