Abstract
An image displaying system interactively changes the positions of the view vector and the viewpoint in the 3-dimensional space of a camera model which displays an object geometric model, constructed within a computer, on the screen in the computer assisted design (CAD) and science art simulation field. The user inputs the object point and the target point on the display screen showing the viewpoint and the view vector direction so as to effect the screen display of the scene with the positions of the view vector and the viewpoint in the 3-dimensional space of the camera model for displaying on the screen the object geometric model constructed within the computer. The scene with the viewpoint and the view vector direction being interactively changed is displayed on the screen.
