Setting Up Projections with AppEasyBlend Plugin

The functionality described in this article is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.

AppEasyBlend plugin allows you to render the UNIGINE-based application on multi-projector setups that are stored in the calibration files created via the Scalable Display Manager and set up via the EasyBlend SDK. The setup can have a complex shape, such as dome.

  • The plugin is available only on Windows with DirectX 11 API (DirectX runtime may need to be updated). OpenGL support is currently experimental.
  • Microsoft Visual C++ 2008 Redistributable Package x64 is required.
  • DPI scaling is not supported.
  • This plugin cannot be used in a Qt-based application.

The plugin supports the fullwindow mode (when the application window is rendered without decorations).

If you run the application in the windowed mode, the window should be non-resizable.

You can toggle the AppEasyBlend plugin via the easyblend console command:

  • To enable, use:
    Source code
    easyblend 1
  • To disable, use:
    Source code
    easyblend 0
