Ship hull fitting using NURBS

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, satisfying certain continuity requirements). One of the restriction in ship hull design is that the existing details of a ship design on paper or a ship that already been constructed physically couldn´t be reconstructed accurately and concisely in a ship hull design software. This problem can take on many different characteristics, depending on the goal of the reconstruction, the origin of the offset, and tools or methods available to tackle the job. All of these must be taken into account in developing the best approach to solving the problem in the most efficient manner. In this research, the implementation of NURBS method is used because it brings the most convincing results.
