ABSTRACT:
A curved surface generated on a closed curve is expressed by an equation of a film having a physical property. The film is considered as a virtual elastic film generated on the closed curve. A curved surface is generated on the closed curve through changing the shape of the elastic film by operator's setting of both the mechanical force of the elastic film and the normal direction of the elastic film on the closed curve.
