1. CALCULUS OF AFFINE STRUCTURES AND APPLICATIONS FOR ISOSURFACES / CÁLCULO DE ESTRUTURAS AFINS E APLICAÇÃO ÀS ISOSSUPERFÍCIES
Differential Geometry provides a set of measures invariant under a set of transformations, in particular rigid, affine, and projective. The invariants by rigid motions are using almost all applications of computer graphics and geometric modeling. The affine case, since it is more general, allows to extend these tools. In this work, geometric properties are p

2. Edge transformations for improving mesh quality of marching cubes
Marching Cubes is a popular choice for isosurface extraction from regular grids due to its simplicity, robustness, and efficiency. One of the key shortcomings of this approach is the quality of the resulting meshes, which tend to have many poorly shaped and degenerate triangles. This issue is often addressed through postprocessing operations such as smoothin

3. Edge Groups : an approach to understanding the Mesh quality of Marching Methods
Marching Cubes is the most popular isosurface extraction algorithm due to its simplicity, efficiency and robustness. It has been widely studied, improved, and extended. While much early work was concerned with efficiency and correctness issues, lately there has been a push to improve the quality of Marching Cubes meshes so that they can be used in computatio

5. Grupos de arestas : uma nova abordagem para entender a qualidade da malha gerada pelo Marching Cubes e suas variantes / Edge groups: a new approach to understanding the mesh quality of marching cubes and its variants
Este trabalho descreve uma nova visão sobre um dos algoritmos mais importantes da Computação Gráfica, o algoritmo para a poligonização de isosuperfícies Marching Cubes (MC). Esta visão permite o estudo das situações onde são gerados triângulos de baixa qualidade, uma das grandes deficiências do MC, e serve como suporte à proposta de modificaç�

6. VISUALIZATION OF THE BOUNDARY BETWEEN FLUIDS USING THE SPH METHOD AND THE MARCHING CUBES ALGORITHM / VISUALIZAÇÃO DA FRONTEIRA ENTRE FLUIDOS UTILIZANDO O MÉTODO SPH E O ALGORITMO DE MARCHING CUBES
In engineering and special effects for film and television, fluid modeling is frequently used to simulate natural phenomena, such as fire, explosions, smoke, water, and air. Basically, this modeling uses mesh-based methods, such as finite volumes and finite elements, or mesh-free methods based on particles, such as MPS and SPH. A common question among partic

7. Converting CSG models into meshed B-Rep models using euler operators and propagation based marching cubes
The purpose of this work is to define a new algorithm for converting a CSG representation into a B-Rep representation. Usually this conversion is done determining the union, intersection or difference from two B-Rep represented solids. Due to the lack of explicit representation of surface boundaries, CSG models must be converted into B-Rep solid models when

8. Visualização de volumes em morfometria de estruturas cerebrais a partir de imagens de ressonância magnética nuclear.
Este trabalho apresenta uma ferramenta computacional para a visualização de volumes anatômicos em procedimentos de morfometria de estruturas cerebrais, visando o auxílio computadorizado ao diagnóstico e avaliação clínica da epilepsia do lobo temporal. As estruturas de interesse são segmentadas manualmente corte a corte produzindo volumes que são se
