摘要
A free-form surface generating method. There is a generating of a continuity condition by detecting a continuity on a common boundary of two free-form surfaces based on tangent vectors on a NURBS common boundary curve and tangent vectors on boundary curves continuous to end points of the NURBS common boundary curve. Next, one of a plurality of predetermined joining processes is selected in accordance with the continuity condition. Then, internal control points of each of the two free-form surfaces are generated based on the selected joined with continuity on the common boundary are generated.
