Updates the recorder according to the elapsed time.

Parameters:

elapsedTime - time between two render frames

getRecordedCameraFlight

public CameraFlight getRecordedCameraFlight()

Returns the recorded camera flight.

Returns:

recorded camera flight

save

public void save(java.lang.String pathToFile)

Saves the recorded camera flight to a file with the specified file path. There will only be saved something if there are checkpoints assigned to the flight.

Parameters:

pathToFile - path to the file into which the recorded data gets saved
