| The use of developable surfaces in design is of engineering importance because they can be easily manufactured without stretching or tearing, or without the use of heat treatment. This paper presents application examples of ship hulls that are of direct application on shipyards, although the method is applicable to other fields like architecture. In this paper, a method to create a developable B-spline surface between two limit curves is presented. Between each pair of these boundary curves or directrix lines, the generator lines or rulings are created and a quasi-developable B-spline surface containing the rulings is defined. A procedure based on multiconic development is used to modify the directrix lines in case the rulings intersect inside the boundary curves, avoiding non-developable portions of the surface. B-spline curves and surfaces are widely used today in practically all the design computer programs. Some examples of ship hulls entirely created with developable surfaces are presented | |
