1. Desenvolvimento de projeto gráfico para interface de usuário de software de modelagem tridimensional : uma abordagem ergonômica
Esta dissertação apresenta um framework de desenvolvimento de uma interface gráfica de usuário para um sistema de modelagem poligonal tridimensional, a partir de critérios ergonômicos que atendam os requisitos fundamentais de usabilidade. A pesquisa foi especialmente orientada a satisfazer principalmente as necessidades individuais dos diferentes perfi

2. Métodos para aproximação poligonal e o desenvolvimento de extratores de características de forma a partir da função tangencial
Whereas manually drawn contours could contain artifacts related to hand tremor, automatically detected contours could contain noise and inaccuracies due to limitations or errors in the procedures for the detection and segmentation of the related regions. To improve the further step of description, modeling procedures are desired to eliminate the artifacts in

3. UMA COMPRESSÃO SIMPLES PARA MALHAS IRREGULARES COM ALÇAS / A SIMPLE COMPRESSION FOR IRREGULAR MESHES WITH HANDLES
Many applications need to transmit 3D models over the Internet, among those data sharing between collaborative environments situated in different locations. Those data sharing aim to analyze and visualize them but bandwidth constraints and storage costs limit the complexity of models than can be transmitted/stored. Polygonal meshes are used in different area

4. A TOPOLOGICAL APPROACH FOR MESH SIMPLIFICATION / UMA ABORDAGEM TOPOLÓGICA PARA SIMPLIFICAÇÃO DE MALHAS
Many applications, in mathematics, computer graphics, medical imaging, geophysics and others, have used the representation of solids by their boundary surface, usually polygonal meshes. Those meshes can represent, with high precision, the geometric properties of the boundary surface of solid and also store important topological surface properties as genus, b

5. Caracterização de reservatorio atraves de tecnicas estatisticas multivariadas e modelagem estocastica no campo de baixa do algodão, Bacia Potiguar
The modeling of reservoir heterogeneities has been largely improved by the petroleum industry over the years. Traditional mapping (hand contouring, deterministic interpolation techniques, and polygonal methods) are not efficient in the prediction of reservoir heterogeneities. Geostatistical techniques provide a more realistic reservoir description, since the
