    Abstract
  • In allusion to the ship hull surface modelling in simulation system of loading and unloading awkward length cargo, this paper provided the main steps of reconstructing ship hull surface by NURBS (non-uniform rational B-spline). According to the points in offset table, the knot vector was calculated with an accumulative chord length parameterization, the global interpolative crosscut lines and waterlines were available with NURBS technology, and the regulative interpolative grid of ship surface was made, thus the ship surface presented with NURBS was reconstructed. The simulation results show that the 3-D ship hull surface reconstructed by NURBS is highly real, this method is feasible.
