Skeletons have proved to be a successful tool in modeling complex shapes. They provide a basis for many processes ranging from implicit modeling, to deformation and animations. In this work we advance in two topics related with skeleton modeling: quad dominant skeleton-based meshes and smooth implicit surfaces generated from a skeleton. Given a skeleton made of line segments we describe how to obtain a coarse quad mesh of a surface that tightly encloses the skeleton and follows its structure - the scaffold. We formalize as an Integer Linear Program the problem of constructing an optimal scaffold that minimizes the total number of quads on the mesh. We prove the feasibility of the Integer Linear Program for any skeleton. In particular we can...
