The shape of a NURBS curve or surface is defined by the location of its control points, the control points' weights, and the knot vectors. Most of the curve and surface design tried to modify the control points. However, it is still impossible to obtained accurate control points for a reconstructed NURBS curve or surface. The fitness of these surfaces is(More)
Ship hull form module is the main module in ship design. The problem of creating fair ship hull surface is of major importance in computer aided ship design environment. The fairness of these surfaces is generally considered a subjective notion depending on the judgment of the designers (e.g. visually pleasing, devoid of unnecessary bumps or wiggles,(More)
