Separate Images Output with AppSeparate Plugin

An AppSeparate plugin is used to create a separate window for each eye. It can be used with any devices that support separate images output, e.g. for 3D video glasses or helmets (HMD)

  • The AppSeparate plugin is available only on DirectX 11 graphics API. So it can be used under Windows only.
  • This plugin cannot be used in a Qt-based application.

AppSeparate can be rendered in both the windowed and the full screen mode.

Launching AppSeparate

To use the plugin, specify the extern_plugin command line option and STEREO_SEPARATE define on the start-up:

Shell commands
main_x86d -extern_plugin "AppSeparate" -extern_define STEREO_SEPARATE

Also you can create a new project with the AppSeparate plugin support by checking the Dual output stereo 3D option on the New Project tab of the UNIGINE SDK Browser.

The engine automatically loads the appropriate version of the library depending on the specified main application. So you can use 32-bit, 64-bit, debug or release versions of the library.

It is not possible to use the AppSeparate plugin with:

Customizing AppSeparate

Unigine-based application can be used with any custom device that supports an output of separate image pairs. You simply need to do the following:

  1. Define the application behaviour when the STEREO_SEPARATE define is set on the start-up or in the configuration file:
    Source code (C++)
    	// implement your code here
  2. Implement the input device interface using an extensible C++ API.

Stereo settings that control eye separation and distance to the zero parallax plane are added to GUI by data/core/scripts/system/stereo.h script and can be controlled from there.
