PURPOSE:To reproduce optionally a deformed curved surface in a converting process, in accordance with necessity, by storing and saving a parameter used in a converting operation continued successively, in a command list memory. CONSTITUTION:A mouse 4, levers 5-7, and a track ball 8 are provided as input operating pieces for inputting a parameter required for an operation, on a curved surface arithmetic unit 1. When setting by the mouse 4 and the levers 5-7 is ended, the curved surface arithmetic unit 1 executes an operation. A result of its operation is brought to a rotational conversion by visual point position information which is inputted from the track ball 8 and thereafter, displayed on a display device 3 through a curved surface display control device 2. A parameter used in a converting operation continued successively in stored and saved in a command list memory provided the curved surface arithmetic unit 1. |
