EGL (API)

Stable release
  
1.5 / March 19, 2014; 2 years ago (2014-03-19)

EGL is an interface between Khronos rendering APIs (such as OpenGL, OpenGL ES or OpenVG) and the underlying native platform windowing system. EGL handles graphics context management, surface/buffer binding, rendering synchronization, and enables "high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs." EGL is managed by the non-profit technology consortium Khronos Group.

Contents

The acronym EGL is an initialism, which starting from EGL version 1.2 refers to Khronos Native Platform Graphics Interface. Prior to version 1.2, the name of the EGL specification was OpenGL ES Native Platform Graphics Interface. X.Org development documentation glossary defines EGL as "Embedded-System Graphics Library".

Adoption

  • The BlackBerry 10 and BlackBerry Tablet OS mobile device operating system uses EGL for 3D graphics rendering. Both support EGL version 1.4.
  • The Android mobile device operating system uses EGL for 3D graphics rendering.
  • The Wayland display server protocol uses EGL. It is implemented in a way that Wayland clients will draw directly to the framebuffer using EGL.
  • Mesa 3D has an implementation of EGL formerly known as Eagle.
  • The Mir display server protocol by Canonical Ltd. uses EGL.
  • The Simple DirectMedia Layer toolkit has been ported to use EGL. It can use Xlib, write directly to the framebuffer or use EGL.
  • The Raspberry Pi single-board computer has an EGL interface to hardware-accelerated 3D graphics rendering.
  • The proprietary Nvidia driver 331.13 BETA from 4 October 2013 supports the EGL API.
  • Tizen OS uses EGL with either OpenGL ES 1.1 or OpenGL ES 2.0 for 3D graphics rendering

    • Implementations

  • Mesa is a free and open-source software implementation of many graphic rendering APIs; among them is EGL.
  • Generic Buffer Management is an API to manage buffers.
