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."[2] EGL is managed by the non-profit technology consortium Khronos Group.
The acronym EGL is an initialism, which starting from EGL version 1.2 refers to Khronos Native Platform Graphics Interface.[3] Prior to version 1.2, the name of the EGL specification was OpenGL ES Native Platform Graphics Interface.[4] X.Org development documentation glossary defines EGL as "Embedded-System Graphics Library".[5]
Adoption
[edit]- The BlackBerry 10 and BlackBerry Tablet OS mobile device operating system uses EGL for 3D graphics rendering. Both support EGL version 1.4.[6]
- The Android mobile device operating system uses EGL for 3D graphics rendering.[7]
- The Wayland display server protocol uses EGL.[8] 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.[9]
- The Mir display server protocol by Canonical Ltd. uses EGL.[10]
- 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.[11]
- The proprietary Nvidia driver 331.13 BETA from 4 October 2013 supports the EGL API.[12]
- Tizen OS uses EGL with either OpenGL ES 1.1 or OpenGL ES 2.0 for 3D graphics rendering[13]
Implementations
[edit]- 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.
