Abstract
A graphic display apparatus for rotating a three-dimensional figure about the three axes of the Cartesian coordinate system has a graphic information storing unit for storing graphic information of a three-dimensional object to be displayed, a rotative action indicating unit for indicating rotative actions to rotate the three-dimensional object being displayed about the three axes, a display coordinate calculating unit for calculating coordinates of the three-dimensional object after it is rotated, a rotational angle calculating unit for calculating rotational angles of the three-dimensional object after it is rotated, and a display unit for displaying the three-dimensional object after it is rotated and the calculated rotational angles. The rotational angle calculating unit calculates the rotational angles of the three-dimensional object rotated by the rotative action, as rotational angles from the initial state of the three-dimensional object in a predetermined sequence of three rotative actions. This arrangement allows the operator to subsequently reconstruct the desired rotated state of the displayed three-dimensional figure without concern over the contents and sequence of rotative actions that have already been made, simply by entering the calculated rotational angles successively in a given sequence from the initial state.
