    The computation of the largest planar region approximating a 3D object is an important problem with wide applications in modeling and rendering. Given a voxelization of the 3D object, we propose an efficient algorithm to ...
  • Hoops: 3D curves as conservative occluders for cell visibility 

    Brunet Crosa, Pere; Navazo Álvaro, Isabel; Rossignac, Jarek; Saona Vázquez, Carlos Luis (North Holland, 2001-08)
    Article

    Most visibility culling algorithms require convexity of occluders. Occluder synthesis algorithms attempt to construct large convex occluders inside bulky non-convex sets. Occluder fusion algorithms generate convex occluders ...
  • Optimal iso-surfaces 

    Andújar Gran, Carlos Antonio; Brunet Crosa, Pere; Chica Calaf, Antonio; Navazo Álvaro, Isabel; Rossignac, Jarek; Vinacua Pla, Álvaro (2004-05)
    Article
    Open Access
    Since the publication of the original Marching Cubes algorithm, numerous variations have been proposed for guaranteeing water-tight constructions of triangulated approximations of iso-surfaces. Most approaches divide the ...
  • Optimizing the topological and combinatorial complexity of isosurfaces 

    Andújar Gran, Carlos Antonio; Brunet Crosa, Pere; Chica Calaf, Antonio; Navazo Álvaro, Isabel; Rossignac, Jarek; Vinacua Pla, Álvaro (Elsevier, 2005-07)
    Article

  • ShieldTester: cell-to-cell visibility test for surface occluders 

    Navazo Álvaro, Isabel; Rossignac, Jarek; Jou, J; Shariff, R (North Holland, 2003-09)

    We present a novel Cell-To-Cell Visibility (C2CV) algorithm, which given two polyhedra,A and B and a connected and oriented manifold triangle mesh, S offers a simple, fast, and conservative test for detecting when A and B ...
