PROBLEM TO BE SOLVED: To deform a shape of a figure with a conversion rate which is not uniform without changing an order of a free curved line and a free curved surface, and easily deform the shape of the figure on the basis of a figure of a circle or a sphere. SOLUTION: Inputting of a value of a center point C1 expressed by a coordinate value of an order coordinate system representing a given circle or sphere, a value of a center point C2 expressed by a coordinate value of an order coordinate system representing a different given circle or sphere, and a value of an equal radius r of these circles or spheres is accepted (steps S4, S5, and S8). Then, values of a plurality of points P in a coordinate representing a plane figure or a solid figure expressed by coordinate values of the given order coordinate system are converted into values of points P* in the coordinate expressed by coordinate values of the order coordinate system by performing operation which parameter is the two circles or two spheres around the points C1, and C2 (a step S11). |
