A method for generating developments using decomposition into the meaningful components of 3D polygon models

Abstract

We propose a method for generating developments from 3D polygon models automatically. The conventional method generates the developments whose components are not interfering each together, by using collision detection between all polygons. However, for the model which consists of a large number of polygons, it is necessary to decompose the development into several parts manually. Therefore it is difficult to generate the development which is easy to be assembled. Our method decomposes the polygon model into meaningful components such as arms, legs, and so on, and develops them. This makes it easy to understand which parts should be glued together, and handcraft bending or folding the developments when a user assembles the paper craft.
