PURPOSE:To produce a shaped from accordant with the features of a shaping object by correcting the shaping degree with a freedom degree limiting parameter showing the moving facility of the deformed part of the shaping object. CONSTITUTION:The picture showing a shaping object 7 is displayed on an original screen SOR and a prescribed deformed area VCF is designated. A position vector U showing the deforming degree of a curved surface within the VCF is obtained for each point in the VCF from the value of multiplication of a vector field function Fi by a deformed vector Vi. Then the features of the surface part of the object 7 are corrected by a freedom degree limiting parameter 13 against the vector U. Thus the deforming degree can be corrected in accordance with the characteristics of the object 7. Then a shaped form is produced effectively according to the actual circumstances. |
