SourcesĪNGLE repository is hosted by Chromium project and can be browsed online or cloned with git clone The translator targets Desktop GLSL, Vulkan GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment. OpenGL ES 3.1: ANGLE 2.1.0.f5dace0f1e57 (Jul, 2020)ĪNGLE also provides an implementation of the EGL 1.5 specification.ĪNGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms.Platform support via backing renderersĪNGLE v1.0.772 was certified compliant by passing the OpenGL ES 2.0.3 conformance tests in October 2011.ĪNGLE has received the following certifications with the Vulkan backend: This version of the specification is thus supported on all platforms specified above that support OpenGL ES 3.0 with known issues. Level of OpenGL ES support via backing renderersĪdditionally, OpenGL ES 1.1 is implemented in the front-end using OpenGL ES 3.0 features. Future plans include ES 3.2, translation to Metal and MacOS, Chrome OS, and Fuchsia support.
ANGLE currently provides translation from OpenGL ES 2.0, 3.0 and 3.1 to Vulkan, desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform.
