Quad Buffered Stereo Support

Unigine has embedded support for Quad Buffered Stereo. This allows using such professional graphics cards as NVIDIA Quadro and AMD FireGL.

To enable the Quad Buffered Stereo mode, perform the following:

1. Make sure that you use the graphics card with the support for Quad Buffered Stereo.
2. Configure the graphics card driver to make your application work correctly.
3. Enable the Quad Buffered Stereo mode in one of the following ways:
   • Via the command line: specify the video_quad_buffer command line option on the application start-up:
     Shell commands

     main_x64 -video_app opengl -extern_define STEREO_QUAD_BUFFER -video_quad_buffer 1

   • Via the console: run the video_quad_buffer console command and restart the video application:
     Source code

     Unigine~# video_app opengl && video_quad_buffer 1 && video_restart

For example, if you use the NVIDIA Quadro graphics card and run your application on Windows, you should configure the NVIDIA driver as follows:

1. Run the NVIDIA Control Panel (click on the desktop with the right mouse button to call the context menu).
2. Select the Manage 3D settings in the left navigation bar.
3. Choose the 3D OpenGL Stereo preset in the Global Settings tab.
4. Configure the Stereo - Display mode parameter (choose Generic active stereo (with Nvidia 3D Vision Support) in the drop-down list if you want to use nVidia 3D-glasses, otherwise choose Generic active stereo - in this case, 3D-glasses will not work).
5. Press the Apply button.
6. Select the Set up stereoscopic 3D in the left navigation bar.
7. Check the Enable stereoscopic 3D.
8. Select when your monitor will be in 3D mode in the drop-down menu (Always is recommended).
9. Press the Apply button.
10. Run your application.
