presetting a plurality of different cameraworks each of which is related to a viewpoint, angle, movement and rotation of an output scene of a simulation image of the virtual ball;

presetting a production mode to implement a simulation image according to each type of the golf shot to be performed by the user in a golf play based on the virtual golf course image by combining two or more preset cameraworks;
