Practical Procedure of a Sport Ship Surface Interpolation and its Application
Abstract. Nowadays, engineering design methodology is carried out by the help of many software tools and hardware devices. Those not only make the work much easier but even became essential. In this paper an example of reverse engineering devices is shown, shoulder to shoulder with product development procedure. The introductory part deals with 3D scanning procedure and 3D model creation. Next part focuses on generative model creating with possibility of its additional modification. Finally, possible applications of such a model are illustrated. A Slovak ship producer assigned a task of improving hydrodynamic characteristics of a sport ship hull. As its manufacture is traditional, without any virtual product development, a task of analyzing the surface of ship's hull came about. For such a purpose, it was necessary to transform the real ship into a CAD model. An optical 3D scanning device was used to gather the cloud of points. After a mesh was generated, the segmentation of continuity boundaries could be applied. The entire shape of ship hull followed the generative algorithm. That allowed any changes based on hydrodynamic flow to be applied directly on surface. For the purpose of gathering cloud of points an optical 3D scanning device was used. In the laboratory of Generative Design, there are two optical sets of lenses.
