PROBLEM TO BE SOLVED: To provide a mesh model deformation technique, capable of automatic generation of a handle based on classification modeling of deformation and also capable of deformation thereof with minimized parameters, by use of a center of gravity coordinate which has a high degree of freedom for relation between a mesh model and the handle and low deformation calculation cost. SOLUTION: This system comprises a deformation range setting means 10 for setting a deformation range to a displayed mesh model by connecting points designated by an operation means 22; a handle generation means 3 determining and generating a deformation space based on the set deformation range as a virtual handle; a center-of-gravity computing means 4 calculating the center-of-gravity coordinate of an apex of the mesh model present in the closed area of the virtual handle; and a deformation processing means 5 moving an apex of the virtual handle to input of a deformation type and an operation parameter of deformation, and recalculating the center-of-gravity coordinate of the apex of the mesh model in interlocking with the movement of the apex of the virtual handle, thereby deforming the mesh model.
