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 Overview )〕 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''.〔(EGL 1.2 Specification )〕 Prior to version 1.2, the name of the EGL specification was ''OpenGL ES Native Platform Graphics Interface''.〔(EGL 1.0 Specification )〕 X.org development documentation glossary defines EGL as "Embedded-System Graphics Library".〔(EGL in X.org development documentation glossary )〕 == Adoption == * The BlackBerry 10 and BlackBerry Tablet OS mobile device operating system uses EGL for 3D graphics rendering. Both support EGL version 1.4.〔http://developer.blackberry.com/native/documentation/core/opengl_es_developer_guide.html〕 * The Android mobile device operating system uses EGL for 3D graphics rendering.〔http://developer.android.com/about/versions/android-2.3-highlights.html〕 * The Wayland display server protocol uses EGL.〔http://ppaalanen.blogspot.com/2012/03/what-does-egl-do-in-wayland-stack.html〕 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.〔(Mesa EGL )〕 * The Mir display server protocol by Canonical Ltd. uses EGL.〔https://wiki.ubuntu.com/MirSpec〕 * 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.〔http://elinux.org/RPi_VideoCore_APIs〕 * The proprietary Nvidia driver 331.13 BETA from supports the EGL API.〔(【引用サイトリンク】title=Added support for the EGL API on 32-bit platforms. Currently, the supported client APIs are OpenGL ES 1.1, 2.0 and 3.0, and the only supported window system backend is X11. )〕 * Tizen OS uses EGL with either OpenGL ES 1.1 or OpenGL ES 2.0 for 3D graphics rendering〔https://wiki.tizen.org/wiki/Porting_Guide/Graphics_and_UI〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「EGL (API)」の詳細全文を読む スポンサード リンク
