The proposed method uses a set of mesh operators and simple rules for selective mesh refinement, with a strategy based on Kohonen s self-organizing map. Basically, a self-adaptive scheme is used for iteratively moving vertices of an initial simple mesh in the direction of the set of points, ideally the object boundary. Successive refinement and motion of vertices are applied leading to a more detailed surface, in a multi-resolution, iterative scheme. Reconstruction was experimented with several point sets, induding different shapes and sizes. Results show generated meshes very dose to object final shapes. We include measures of performance and discuss robustness.application/pdfAcesso AbertoReconstrução de SuperfíciesRedes de KohonenMulti-ResoluçãoSurface ReconstructionKohonen NetworksMulti-ResolutiondoctoralThesisCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA
