Skeletonization and Decomposition of Volumetric Models based on Dimensionality

Abstract

When we use volumetric models in digital engineering like CAD/CAM/CAE, we ordinary polygonize them by contouring the entire objects ″or″ extracting medial surfaces, but it's desirable to apply different modeling approach according to the shape of each parts. In this paper, we propose a new modeling method which is based on decomposition by dimensionality, which is composed of solid, plane and wire. And we also propose a new skeletonization method affecting the final results of this method, which can extract simpler skeletons with fewer branches from even noisy data than before.
