WebNov 1, 2013 · The authors rightfully point out that NURBS do have their problems when applied to ship hull modelling. The review mentions T-splines as a promising solution, … WebConstructing N -sided surface patches to fill holes plays an important role in Computer Aided Geometric Design. In this paper, we present a method to construct a single toric surface patch interpolating N -sided boundary curves. The control points of the patch are determined by the given boundary curves and energy optimization. The main advantage …
