    • A conceptual image-based data glove for computer-human interaction 

      Fernandes, Leandro Augusto Frata; Pamplona, Vitor Fernando; Prauchner, João Luis; Nedel, Luciana Porcher; Oliveira Neto, Manuel Menezes de (2008) [Journal article]
      Data gloves are devices equipped with sensors that capture the movements of the hand of the user in order to select or manipulate objects in a virtual world. Data gloves were introduced three decades ago and since then ...
    • Edge Groups : an approach to understanding the Mesh quality of Marching Methods 

      Dietrich, Carlos Augusto; Scheidegger, Carlos Eduardo; Comba, Joao Luiz Dihl; Nedel, Luciana Porcher; Silva, Cláudio Teixeira (2008) [Journal article]
      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 ...
    • Edge transformations for improving mesh quality of marching cubes 

      Dietrich, Carlos Augusto; Scheidegger, Carlos Eduardo; Schreiner, John; Nedel, Luciana Porcher; Comba, Joao Luiz Dihl; Silva, Cláudio Teixeira (2009) [Journal article]
      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 ...
