Abstract:
1. A method for generating/displaying a plane shape, comprising the steps of: setting a normal line, which is equivalent to a tangent plane of a curved surface of an object shape, at each vertex of a triangle shape plane patch which is a basic form necessary for generating/displaying the object shape, decomposing, in a specific direction, said set normal line on a tangent plane at said each vertex of the triangle shape plane patch, thus setting a tangent line; forming, between two corresponding vertexes of said triangle shape plane patch and in a direction based on said two corresponding vertexes, an equivalent normal line that becomes a new tangent plane of the object shape; determining another tangent line at where said normal line is formed; and further determining a normal line equivalent to the tangent plane of the curved surface, thus creating the object shape; and displaying the object shape on a display.
