PURPOSE:To immediately display shape in which plural pieces of threedimensional coordinate data are unified when a set of them exists and to refer to relationship between them in a shape expressing method in a graphic system. CONSTITUTION:Three-dimensional shape in which the set of three-dimensional coordinate data and plural pieces of surface descriptive data are unified when they exist by attaching reliability 30, 31 possessed by surface shape on attribute data in the shape expressing method in which the set of three-dimensional coordinate data repesenting the position of a sampling point on the surface of a material, the surface descriptive data representing the surface shape by linking those three-dimensional coordinate data, and the attribute data for each surface shape are provided. |
