PURPOSE:To continuously generate intermediate forms by providing the input means of a control parameter to control a curved surface form change, and a mixed form determining means to continuously change the mixed form of two curves according to the change of the control parameter. CONSTITUTION:An input means 10 of the curve, an input means 11 of the control parameter to control the curved surface form change, a mixed form determining means 13 to continuously change the mixed form of the two curves according to the change of the control parameter, a mixing means 14 to mix the spatially facing curves based on the mixed form determined by the mixed form determining means 13, and a calculating means 16 to calculate the point on the curved surface of the data mixed by the mixing means 14 are provided. Consequently, the mixed form of the two curves can be controlled by the mixed form determining means 13. Thus, the intermediate forms can be continuously generated. |
