PURPOSE:To obtain the flexible generating method where a three-dimensional form model is first roughly generated and is gradually deformed thereafter by interlocutorily correcting the positional direction of an arbitrary face of the generated three-dimensional form to easily deform the three-dimensional form model. CONSTITUTION:A projecting polyhedron cutting means 102, a section setting means 103, a face selecting means 104, an initial projecting polyhedron generating means 105, an adjacent face fetch means 106, a face inverting means 107, and a projecting polyhedron joining means 108 are provided. Initial projecting polyhedrons are interlocutorily cut, and obtained projecting polyhedrons are joined with designated faces, and the positional direction of an arbitrary face of the generated three-dimensional form is corrected. Thus, the three-dimensional form model is easily deformed. |
