The problem of surface flattening is an important one in pattern engineering. Surface flattening is needed for the design of thin-walled objects, such as airplanes wings, outer ship hulls, parts of car bodies, shoe uppers, and textile products. Although composite materials can be used for building modern ships, hulls, steel is still the most commonly used material for the ship-building industry. Therefore, the pattern engineering process still has an important role in ship designing. For most of the ship's hull the flattening is quite simple; the problem is the flattening of the stem and the stern, because the surfaces of these parts of the ship are very complex, and therefore an efficient surface-flattening algorithm is needed. In this article a new fast algorithm for surface reconstruction and surface flattening, based on a divide-and-conquer strategy, is presented. Developable stripes are used to approximate the surface, and in this way the surface can be flattened quickly and without any distortion.
