The present invention relates to a POI (point of interest) operation for moving an object corresponding to a selected node to the center of an editing window as pre-processing for changing the viewpoint of an object displayed in three-dimensional virtual space in a window of a display device. A node displayed in a pop-up menu in a first window is selected by a mouse 262. A model editing tool 420 displays an object corresponding to the selected node in a second window. After a confirmation operation by the user by the mouse 262, the model editing tool 420 preferably enlarges and moves the display of the object to the center of the second window. Next, when the user selects a "Rotate", "Move", "Scale", or other operation mode in the "Conductors" window by the mouse and draws on or clicks the inside of the display screen by the mouse 262, the model editing tool 420 rotates, moves, or enlarges the image of the object in accordance with the operation mode of the mouse and the operation of the user. As a result, the object can be viewed from different viewpoints.
