PROBLEM TO BE SOLVED: To provide a deformation operation method of an object capable of stably deforming and displaying the object even in physical modeling while reducing an arithmetic processing burden.SOLUTION: The deformation operation method of an object OB for performing a deforming operation on the object OB displayed on a display device includes the steps of: setting a polygon POL around any arbitrary point P0 within the object OB by a control device that controls the display device; dividing a space within the polygon POL with a vector from the center P0 of the polygon POL to vertices P1-P12 of the polygon POL; discriminating the space in which vertices of the object OB are included, from among the divided spaces; storing a disassembly coefficient of a vertex POB of the object OB with three vectors forming the space including the vertex POB of the object OB; and deforming and displaying the object OB in accordance with the deforming operation acting on the polygon POL. |
