Skeleton-guided mesh cylindrical parametrization

Abstract

Previous planar parametrization methods cannot be applied to 0-genus closed mesh models directly and spherical parametrization is mainly applicable to the models whose shapes are close to the sphere. In this paper, we define a hyper-cylindrical parametric domain and present a progressive cylindrical parametrization algorithm. Such an algorithm can be applied to the mesh models which have a simple skeleton or resemble the cylinder. We further present a skeleton-guided mesh cylindrical parametrization method such that the models with strong skeletons can be globally parameterized. The parametric domain is purely determined according to model shape, relieving geometric distortion caused by parametrization. The model is segmented into the main body and several branches. We parameterize each of them and finally stitch the parameterized branches onto main body. We verify the effectiveness of the cylindrical parametrization method through experiments and show its application to constrained texture mapping.
