摘要: Current scan technologies provide huge data sets which have to be processed considering several application constraints. The different steps required achieve this purpose use a structured approach where fundamental tasks, e.g. surface reconstruction, multi-resolution simplification, smoothing and editing, interact using both the input mesh geometry topology. This paper is twofold; firstly, we focus our attention on duality basic relationships between 2-manifold triangle \({\mathcal M}\) its dual representation M}'\). achieved combinatorial properties represent starting point for reconstruction algorithm maps M}'\) into primal M}\), thus defining their geometric topological identification. correspondence further analyzed in order study influence of information process. second goal definition “dual Laplacian smoothing”, combines well-known algorithms with an inverse transformation reconstructing regularized mesh. instead exploits mask from 1-neighborhood one, related Laplacian-based algorithms, guaranteeing good results optimizing storage computational requirements.
