    Description

    If one consider the hull of modern commercial vessel, then 90% of the hull is quite simple. The midship section is more or less a simple cylinder; but the bulbous bow and the stern with the propeller bossing has a very complex geometry and the transition from the simple cylindrical shape to the complex double curved shapes at the bow and stern gives the designer many problems. It also makes the use of ordinary B-spline or NURBS surfaces difficult. In the project we propose to use a generalization of NURBS-surfaces by Frank Weller to model ship hulls.
    As an other part of the project we want to replace the tedious manual fairing of the ship hull by an automated process which minimizes a suitable chosen fairness measure. The surface fairness measure is derived by demanding that all the planar intersection curves shall have a small curvature variation.
