什么是 EGL 以及如何使用它

问题描述

谁能解释一下什么是 EGL 以及它的作用是什么?

如何在 Linux 上将 EGL 与 OpenGL-ES 结合使用?

EGL 是介于硬件和操作系统之间的层吗?

解决方案

有一个实现，称为 EGL 和 在 Mesa EGL Wiki 中有介绍.实际上你不能使用 XEGL/EGL,

如果您在 Linux 上运行并且不需要 X，那么请查看 Wayland 这是一个建立在 MESA 之上的替代服务器.

Can Anybody explain me what is EGL and what it does?

How can i use EGL with OpenGL-ES On Linux?

Is EGL a Layer Between Hardware And Operating System?

解决方案

EGL is a window system-independent equivalent to the GLX and WGL APIs, which respectively enable OpenGL support in X and Microsoft Windows. It 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.

There is an implementation for Mesa called EGL and covered in the Mesa EGL Wiki.Realistically you can't use XEGL / EGL,

If you're running on Linux and don't need X then look at Wayland which is a replacement server built on top of MESA.
