GLX Provides a way to do OpenGL drawing into a window managed by the X server. Almost always available in software. The open drivers use the DRI to accelerate
GLX provides the glue connecting OpenGL® and the X Window System™ and is required by any OpenGL implementation using X. SGI is releasing its implementation of GLX under a public source license. This action, together with additional programming work being contributed to open source by Precision Insight, Inc., will extend the reach of OpenGL to a new category of platforms: Linux, BSD, and other operating systems using the popular XFree86 implementation of X.
The GLX release itself is targeted at developers working with XFree86.
GLX是OpenGL Extension to the X Window System的縮寫。它作為x的擴展，是x協定和X server的一部分，已經包含在X server的代碼中了。GLX提供了x window system使用的OpenGL接口，允許通過x調用OpenGL庫。OpenGL 在使用時，需要與一個實際的視窗系統關聯起來。在不同平台上有不同的機制以關聯視窗系統，在Windows上是WGL，在Linux上是GLX，在Apple OS上是AGL等。
