<p>PROBLEM TO BE SOLVED: To provide the three-dimensional image viewpoint instructing device which can instruct display facing or a display direction based upon spatial thinking as the facing of a three-dimensional body in a three-dimensional space generated on a computer or the display direction in the space without considering spatial coordinates of an X, a Y, and a Z axis, etc. SOLUTION: A CPU 1 moves the body in the three-dimensional space on the computer according to rotation information from the instructing device 7 and displays it on a display device 4 when a key A is depressed, and the CPU enlarges or reduces the display on the display device 4 about the body when a slide key B is pressed and performs initialization resetting for fine- quantity rotation unless the slide key B is operated. Rotation in the X-axial direction is performed by +1 deg. with a key C and by -1 deg. with a key D, rotation in the Y-axial directions is performed by +1 deg. with a key E and by -1 deg. with a key F, and rotation in the Z-axial direction is performed by +1 deg. with a key G and by -1 deg. with a key H; and the body in the three-dimensional space on the computer which is already selected is moved based on the totalized angle and displayed on the display device 4.</p> |
