Unigine::Plugins::SpiderVision::CalibrationGridData Class
Header: | #include <plugins/Unigine/SpiderVision/UnigineSpiderVision.h> |
Calibration Grid stores the data on the calibration grid adjustments of the current configuration.
Calibration grid is in fact a grid of a certain shape (sphere or box) with a specified distance between the lines of this grid. The grid helps aligning the images rendered by projectors to obtain a seamless image.
Notice
The calibration grid data are not stored in the configuration file.
This object is accessible via the corresponding method of the DisplaysConfig class.

event triggered on changing calibration grid data. You can subscribe to events via connect() and unsubscribe via disconnect(). You can also use EventConnection and EventConnections classes for convenience (see examples below).
The event handler signature is as follows: myhandler()Notice
For more details see the Event Handling article.
Usage Example
Source code (C++)
// implement the Changed event handler
void changed_event_handler()
{
Log::message("\Handling Changed event\n");
}
//////////////////////////////////////////////////////////////////////////////
// 1. Multiple subscriptions can be linked to an instance of the EventConnections
// class that you can use later to remove all these subscriptions at once
//////////////////////////////////////////////////////////////////////////////
// create an instance of the EventConnections class
EventConnections changed_event_connections;
// link to this instance when subscribing to an event (subscription to various events can be linked)
CalibrationGridData::getEventChanged().connect(changed_event_connections, changed_event_handler);
// other subscriptions are also linked to this EventConnections instance
// (e.g. you can subscribe using lambdas)
CalibrationGridData::getEventChanged().connect(changed_event_connections, []() {
Log::message("\Handling Changed event (lambda).\n");
}
);
// ...
// later all of these linked subscriptions can be removed with a single line
changed_event_connections.disconnectAll();
//////////////////////////////////////////////////////////////////////////////
// 2. You can subscribe and unsubscribe via an instance of the EventConnection
// class. And toggle this particular connection off and on, when necessary.
//////////////////////////////////////////////////////////////////////////////
// create an instance of the EventConnection class
EventConnection changed_event_connection;
// subscribe to the Changed event with a handler function keeping the connection
CalibrationGridData::getEventChanged().connect(changed_event_connection, changed_event_handler);
// ...
// you can temporarily disable a particular event connection to perform certain actions
changed_event_connection.setEnabled(false);
// ... actions to be performed
// and enable it back when necessary
changed_event_connection.setEnabled(true);
// ...
// remove subscription to the Changed event via the connection
changed_event_connection.disconnect();
//////////////////////////////////////////////////////////////////////////////
// 3. You can add EventConnection/EventConnections instance as a member of the
// class that handles the event. In this case all linked subscriptions will be
// automatically removed when class destructor is called
//////////////////////////////////////////////////////////////////////////////
// Class handling the event
class SomeClass
{
public:
// instance of the EventConnections class as a class member
EventConnections e_connections;
// A Changed event handler implemented as a class member
void event_handler()
{
Log::message("\Handling Changed event\n");
// ...
}
};
SomeClass *sc = new SomeClass();
// ...
// specify a class instance in case a handler method belongs to some class
CalibrationGridData::getEventChanged().connect(sc->e_connections, sc, &SomeClass::event_handler);
// ...
// handler class instance is deleted with all its subscriptions removed automatically
delete sc;
//////////////////////////////////////////////////////////////////////////////
// 4. Subscribe to an event saving a particular connection ID
// and unsubscribe later by this ID
//////////////////////////////////////////////////////////////////////////////
// instance of the EventConnections class to manage event connections
EventConnections e_connections;
// define a particular connection ID to be used to unsubscribe later
EventConnectionId changed_handler_id;
// subscribe to the Changed event with a lambda handler function and keeping connection ID
changed_handler_id = CalibrationGridData::getEventChanged().connect(e_connections, []() {
Log::message("\Handling Changed event (lambda).\n");
}
);
// remove the subscription later using the ID
CalibrationGridData::getEventChanged().disconnect(changed_handler_id);
//////////////////////////////////////////////////////////////////////////////
// 5. Ignoring all Changed events when necessary
//////////////////////////////////////////////////////////////////////////////
// you can temporarily disable the event to perform certain actions without triggering it
CalibrationGridData::getEventChanged().setEnabled(false);
// ... actions to be performed
// and enable it back when necessary
CalibrationGridData::getEventChanged().setEnabled(true);
