四路缓冲立体声支持

Unigine has embedded support for Quad Buffered Stereo. This allows using such professional graphics cards as NVIDIA Quadro and AMD FireGL.Unigine嵌入了对四缓冲立体声的支持。这样就可以使用NVIDIA Quadro和AMD FireGL等专业显卡。

注意

The Quad Buffered Stereo mode can be enabled for OpenGL mode only.只能为OpenGL模式启用Quad Buffered Stereo模式。

To enable the Quad Buffered Stereo mode, perform the following:要启用Quad Buffered Stereo模式，请执行以下操作：

1. Make sure that you use the graphics card with the support for Quad Buffered Stereo.确保在支持四缓冲立体声的情况下使用图形卡。
2. Configure the graphics card driver to make your application work correctly.配置图形卡驱动程序以使您的应用程序正确运行。
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:
     命令行

     main_x64 -video_app opengl -extern_define STEREO_QUAD_BUFFER -video_quad_buffer 1

     Via the command line: specify the video_quad_buffer command line option on the application start-up:
     命令行

     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:
     源代码

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

     Via the console: run the video_quad_buffer console command and restart the video application:
     源代码

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

   Via the command line: specify the video_quad_buffer command line option on the application start-up:
   命令行

   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:
   源代码

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

   启用Quad Buffered Stereo模式可以通过以下方式之一进行：
   • Via the command line: specify the video_quad_buffer command line option on the application start-up:
     命令行

     main_x64 -video_app opengl -extern_define STEREO_QUAD_BUFFER -video_quad_buffer 1

     通过命令行：在应用程序启动时指定video_quad_buffer命令行选项：
     命令行

     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:
     源代码

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

     通过控制台：运行video_quad_buffer控制台命令并重新启动视频应用程序：
     源代码

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

注意

To make sure that the Quad Buffered Stereo mode is enabled, check the log file. The Quad Buffer Context should be added to the OpenGL flags string.要确保启用Quad Buffered Stereo模式，请检查日志文件。四缓冲区上下文应添加到OpenGL标志字符串中。

For example, if you use the NVIDIA Quadro graphics card and run your application on Windows, you should configure the NVIDIA driver as follows:例如，如果您使用NVIDIA Quadro图形卡并在Windows上运行您的应用程序，则应按以下方式配置NVIDIA驱动程序：

1. Run the NVIDIA Control Panel (click on the desktop with the right mouse button to call the context menu).运行NVIDIA Control Panel（使用鼠标右键在桌面上单击以调用上下文菜单）。
2. Select the Manage 3D settings in the left navigation bar.在左侧导航栏中选择Manage 3D settings。
3. Choose the 3D OpenGL Stereo preset in the Global Settings tab.在Global Settings选项卡中选择3D OpenGL Stereo预设。
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).配置Stereo - Display mode参数（如果要使用nVidia 3D眼镜，请在下拉列表中选择Generic active stereo (with Nvidia 3D Vision Support)，否则选择通用有源立体声-在这种情况下，3D眼镜将不起作用）。
5. Press the Apply button.按下Apply按钮。
6. Select the Set up stereoscopic 3D in the left navigation bar.在左侧导航栏中选择Set up stereoscopic 3D。
7. Check the Enable stereoscopic 3D.检查Enable stereoscopic 3D。
8. Select when your monitor will be in 3D mode in the drop-down menu (Always is recommended).在下拉菜单中选择显示器何时处于3D模式（建议使用Always）。
9. Press the Apply button.按下Apply按钮。
10. Run your application.
