    • 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) [Artículo de periódico]
      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) [Artículo de periódico]
      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) [Artículo de periódico]
      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 ...

    • Introdução aos tutoriais do SIBGRAPI 2003 

      Nedel, Luciana Porcher; Frery, Alejandro César (2003) [Artículo de periódico]

    • Marching cubes without skinny triangles 

      Dietrich, Carlos Augusto; Scheidegger, Carlos Eduardo; Comba, Joao Luiz Dihl; Nedel, Luciana Porcher; Silva, Cláudio Teixeira (2009) [Artículo de periódico]

    • Simulação de objetos deformáveis baseada na análise dinâmica 

      Nedel, Luciana Porcher (1998) [Artículo de periódico]
      This work describes a model for the simulation of objects in 3D space. A rectangular mesh is used as the geometric model; each point in the mesh is considered as a particle, when applying the physical mode!. The physical ...

    • Volume sculpting based on geometric tools 

      Huff, Rafael; Rosa Junior, Roberto Silveira da; Nedel, Luciana Porcher; Freitas, Carla Maria Dal Sasso (2009) [Artículo de periódico]
      The analysis of volumetric datasets is the main concern in many areas ranging from geophysics to biomedical sciences. The direct visualization of these data plays an important role in this scenario, and in spite of ...
