EGL is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization and enables high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs.

The EGL registry contains specifications of the core API; specifications of Khronos- and vendor-approved EGL extensions; header files corresponding to the specifications; an enumerant and function registry; and other related documentation. The current version of EGL is EGL 1.5.

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."

2018年11月26日 · 在Java层，EGL封装了两套框架，分别是： 位于javax.microedition.khronos.egl包下的EGL10。 位于android.opengl包下的EGL14。 其主要区别是： EGL14是在Android 4.2(API 17)引入的，换言之API 17以下的版本不支持EGL14。

EGL 是底层原生平台窗口与 Khronos渲染API (如OpenGL ES、OpenVG等) 之间的接口，为OpenGLES等图形API 提供渲染窗口、图形上下文(EGLContext)、同步绘制接口等机制，使其可以与不同的平台窗口建立关联关系，从而实现在不同平台上（如Android、Windows等）的渲染工作。

EGL provides mechanisms for creating rendering surfaces onto which client APIs can draw, creating graphics contexts for client APIs , and synchronizing drawing by client APIs as well as native platform rendering APIs. EGL does not explicitly support remote or indirect rendering, unlike the similar GLX API.

The EGL-Registry repository contains the EGL API and Extension Registry, including specifications, reference pages and reference cards, and the enumerant registry. It is also used as a backing store for the web view of the registry at https://www.khronos.org/registry/egl/; commits to the main branch of this repository will be reflected there.

2021年8月3日 · EGL 是 Khronos 的渲染 API（如 OpenGL ES 或 OpenVG）与底层原生平台窗口系统之间的接口。 它处理图形上下文管理、surface/buffer 绑定和渲染同步，并使用其他 Khronos API 实现高性能、加速、混合模式 2D 和 3D 渲染。

2019年1月31日 · EGL 是 Khronos渲染 API（如OpenGL ES或OpenVG）与底层本机平台窗口系统之间的接口。 在 Android 平台，一般是 OpenGL ES 和底层的 native window system 之间的接口，简单的说，就是 Android 应用层 和 底层window 渲染数据交互的媒介。

EGL™ is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization and enables high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs.
