      Mesas interativas com estereoscopia oferecem capacidades únicas de visualização, permitindo aos utilizadores percecionar objetos virtuais como se estes estivessem em cima da superfície. Com esta capacidade de visualização ...
    • Manipulating Topological Decompositions of Non-Manifold Shapes 

      Canino, David (The Eurographics Association, 2016)
      Decomposing a non-manifold shape into its almost manifold components is a powerful tool for analyzing its complex structure. Many techniques for decomposing a non-manifold shape are available in the current literature, and ...
    • Manual Segmentation and Semantic-based Hierarchical Tagging of 3D models 

      Papaleo, Laura; Floriani, Leila De (The Eurographics Association, 2010)
      Today 3D objects have become widely available in different application domains, thus it is becoming fundamental to use, integrate and develop techniques for extracting and maintaining their implicit knowledge. These ...
