| description | PROBLEM TO BE SOLVED: To provide a method for deforming a three-dimensional computer creation model for changing a shape of a three-dimensional model. SOLUTION: This method includes a step for expressing the surface of the three-dimensional model by using a face expression having an original face definition in the first place, a step for deriving a plurality of smooth three-dimensional mapping functions, a step in which the respective three-dimensional mapping functions define deformation to a curved face and at least one three-dimensional mapping function is a non-affine function, a step for constructing synthesis of a plurality of three-dimensional mapping function and the original face definition and including the respective three-dimensional mapping functions in synthesis sequentially according to retrieval order of the three-dimensional mapping functions, and a step for applying synthesis after inclusion of the sequential three-dimensional mapping function to the synthesis for deforming the surface of the three-dimensional model and keeping smoothness to the minimum smoothness among that of a plurality of mapping functions.
