PURPOSE:To check the interference of a curved surface in a short time by displaying an interference area in color of another curved surface on the curved surface displayed in a certain color without displaying the part of each curved surface hidden behind another curved surface. CONSTITUTION:The curved surface 2a and the curved surface 1b are displayed in different colors on a screen, however, the curved surface 1c of same color as that of the curved surface 1b is displayed in the curved surface 2a. Since the curved surfaces 1b and 1c are of the same color, the curved surface 1c is part of the curved surface 1b, and the curved surface 1c is located at the front of the curved surface 2a. In such a way, the curved surface 1c forms the interference area between the curved surface 2a and the curved surface 1b. In other words, the peripheral curved surface of the curved surface 1c is located behind the curved surface 2a. Similarly, the curved surface 1e of same color as that of the curved surface 1d is displayed in the curved surface 4a, and since they are of same color, the curved surface 1e is part of the curved surface 1d, and also, the curved surface 1e is located at the front of the curved surface 4a. Therefore, the curved surface 1e forms the interference area between the curved surface 4a and the curved surface 1c. In such a way, it is possible to easily recognize the presence/absence of the interference area by displaying the curved surface of another color in the curved surface of certain color. |
