A computer system (10) includes, e.g., a computer (12), a display (14), and a rotation information input device (20). The rotation information input device (20) includes a sphere (22), a tripod (24) that rotatably supports the sphere (22), and a camera (26) that takes an image of the sphere (22). The computer (12) selects two feature points from the image of the sphere (22) taken by the camera (26), and sets two-dimensional coordinates in the image of the feature points. While tracking the feature points, the computer (12) samples the two-dimensional coordinates and transforms them into three-dimensional coordinates on a surface of the sphere (22). Then, the computer (12) calculates a rotation matrix representing a rotation of the sphere (22), based on the three-dimensional coordinates, and multiplies the respective vertex coordinates of the three-dimensional object displayed on the display (14) by the rotation matrix, thereby calculating the respective vertex coordinates of the three-dimensional object after rotated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-dimensional object display control system and method thereof","description":"Provided is a three-dimensional object display control system that enables a three-dimensional object displayed on a screen to be freely rotated by means of instinctive operation.
