AppEasyBlendInterface Class

Header:#include <plugins/AppEasyBlendInterface.h>

The functions described below are available when the AppEasyBlend plugin is loaded.

AppEasyBlend plugin cannot be used in a Qt-based application

If the plugin is loaded together with the engine, the HAS_APP_EASYBLEND definition is set. This definition can be used, for example, to avoid errors if the plugin is not loaded: the code in which the plugin functions are executed can be wrapped around as follows:

The path to calibration file can also be set via the following command-line option: -calibration_file <path_to_calibration_file>


  • const char * file_name - Path to *.ol calibration file to be set. Both relative and absolute paths are supported.

void setAuxRotation(Math::quat rotation)
