Quadrilateral subdivision schemes come in primal and dual varieties, splitting faces or respectively vertices. The scheme of Catmull-Clark is an example of the former, while the Doo-Sabin scheme exemplifies the latter. In this paper we consider the construction of an increasing sequence of alternati

We propose a new general-purpose data structure useful for a variety of three-dimensional applications. The data structure has the characteristic of storing simultaneously the primal and dual subdivisions of a three-dimensional manifold. We argue in this paper that storing both subdivisions, for ins
