What is Angle?

ANGLE stands for Almost Native Graphics Layer Engine. 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. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.

ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and 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. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.

Microsoft to Use Chromium for Edge Browser

The company has already placed the repository on GitHub to attract new members to the development of the browser
07 December 2018   109

Microsoft Vice President Joe Belfiore said that from December 6, 2018, the company will use the Chromium engine in the Microsoft Edge browser. According to him, Microsoft also plans to develop browsers for smartphones and other devices.

The company has already placed the repository on GitHub to attract new members to the development of the browser. Microsoft expects that the transition to the new engine will be a big step in the development of Microsoft Edge. For example, the browser will finally be adapted for macOS.

According to Belfiore, the company plans to improve the project in three areas:

  • Users will get hardware integration, improved browser compatibility with sites and reduced power consumption of devices when using it.
  • Web developers will appreciate the reduced fragmentation of a web platform for testing sites.
  • The corporate IT sector will get the compatibility of old and new Windows applications that run in the browser.

He noted that during the year the company would work “under the hood” of Microsoft Edge, and named several key stages of this process. For example, the transition to a platform compatible with the Chromium engine for developing a desktop version of the browser. It is also planned that most platforms and all versions of Windows will support Microsoft Edge.
