This projects aims to provide Quad-Buffer "emulation" for any OpenGL application.
As you may know OpenGL is able to do Quad-Buffer Stereo for many years.
But it only works with proffessionnal graphic cards, like Nvidia Quadro.

The goal of this project is to provide Quad-Buffer Stereo supports on non-Quad-buffered video cards.


* * COMPILATION * *

Compile the wrapper:
$ make

You can compile in debug mode:
$ make debug


* * USAGE * *

You need to use LD_PRELOAD :
$ LD_PRELOAD=/location/glQuadBufferEmu.so YourQuadBufferedApplication

Example :
$ LD_PRELOAD=./glQuadBufferEmu.so glxgears -stereo

You may want to make the lib available from any directory :
$ cp glQuadBufferEmu.so /usr/lib

Then you may use it just like that :
$ LD_PRELOAD=glQuadBufferEmu.so glxgears -stereo


* * CONFIGURATION * *

EDIT ~/.config/glQuadBufferEmu/glQuadBufferEmu.conf

Modes available :
- Monoscopic (Left or Right) [MONOSCOPIC],
- Anaglyph (any color) [ANAGLYPH],
- Side-by-side (Left/Right; Top/bottom; Frame-packing) [SIDEBYSIDE],
- Frame-sequential (software page-flipping) [FRAMESEQUENTIAL].

Modes in progress :
- Interlaced [INTERLACED]
