Subdivision surfaces are an established modeling tool in computergraphics and computer-aideddesign. While the theoretical foundations of subdivision surfaces are well studied, the correlation between a control mesh and its subdivided limit surface still has some open-ended questions: Which topology should a control mesh have? Where should control vertices be placed? A modeler - human or software - is confronted withthese questions and has to answer them. In this paper we analyze four characteristic situations. Each one consists of an analytical reference surface S and several variants of control meshes C-i. In order to concentrate on the topology of the control meshes, the geometrical positions of their control vertices have been determined and optimized automatically. As a result we identified the best topology of all C-i to represent the given surface S. Based on these results we derived heuristics to model with subdivision surfaces. these heuristics are beneficial for all modelers.
