Topological mesh operators

Topological mesh operators
Thomas Lewiner, Hélio Lopes, Esdras Medeiros, Geovan Tavares, Luiz Velho


In this paper we introduce an unified framework for topological manipulation on triangulated 2-manifolds with or without boundary. We show that there are two kinds of primitive operators on the underlying meshes: operators that change the topological characteristic of the mesh and operators that just modify its combinatorial structure. We present such operators and demonstrate that they provide a complete and coherent set of elementary operations for mesh construction and editing.
