IMAGE DISPLAYING SYSTEM

摘要

The present invention relates to an image displaying system for interactively changing the positions of the view vector and the viewpoint in 3-dimensional space of a camera model which makes visual, an object geometric model constructed within a computer, on the screen in a computer assisting design (CAD) and a 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 3-dimensional space of the camera model for making visible on the screen the object geometric model constructed within the computer. The scene with the viewpoint and the view vector direction are interactively changed as displayed on the screen.
