Abstract
A method and an apparatus for generating sculptured surfaces which enables a sculptured surface of a specified radius to be generated easily between two free curves. A plurality of base points are set on a first free curve, and a plurality of planes are generated at each of the base points using, as the normal, a tangent of the first free line, the planes including that base point. A plurality of intersections of the second free curve and the plurality of planes are determined. A plurality of circular arcs of a specified radius are generated on each of the plurality of planes using the base point and the intersection as endpoints. A sculptured surface is then generated based on the first free curve, the second free curve, and the plurality of circular arcs.
