Abstract
When generating complicated geometries like the hull form of a commercial ship, the hull form deformation approach often involves slightly modifying the geometry to satisfy design requirements based on the hull form of a previously built reference ship. In the industry, methods such as the 1-Cp method or the Lackenby method have been used to edit the hull form by moving the section plane of the reference hull form longitudinally. While these methods have the advantage of quickly deforming the hull form when satisfying design requirements, they have the limitation of having a very limited degree of freedom in hull form deformation. To overcome this limitation, many hull form optimization research have used methods such as Free Form Deformation (FFD) and Radial Basis Function (RBF), which define control points and directly modify the surface of the hull form. Although this approach allows for very flexible deformation of the hull form, it has the limitation that the designer must define the position and direction of movement of the control points, and further consideration of design requirements is required.
