<p><P>PROBLEM TO BE SOLVED: To provide a three-dimensional image processor, a game device, a three-dimensional image processing program and a game program which enable a player to obtain an operation feeling as if actually touching a three-dimensional object. <P>SOLUTION: The game device 10 includes an LCD 4 and a touch panel 22 is provided relating to the LCD 14. On the LCD 14, a game image including an object is displayed. When the player operates a two-dimensionally displayed spherical object so as to rub it by using a stick 24 (stroke operation), the object is plotted (rotated) according to the operation. For instance, when the player performs the stroke operation near the center of the object, in a three-dimensional virtual space, the object is rotated around an X axis and around a Y axis with the center as an origin. Also, when the player performs the stroke operation near the outer periphery of the object, in the three-dimensional virtual space, the object is rotated around the X axis, around the Y axis and around a Z axis with the center as the origin. By this invention, the operation feeling as if actually rolling a spherical body placed on a table can be obtained. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
