    • 3D texture-based hybrid visualizations 

      Boada, Imma; Navazo Álvaro, Isabel (2003-01)
      Article
      Accés restringit per política de l'editorial
      In this paper, the visualization of hybrid scenes that contain volume data and a fitted extracted surface is addressed. The proposed algorithm is based on a integrated octree-based representation: the ‘‘hybrid octree.’’ ...

    • An octree isosurface codification based on discrete planes 

      Boada, Imma; Navazo Álvaro, Isabel (2001)
      Text en actes de congrés
      Accés obert
      Describes a method to code a decimated model of an isosurface on an octree representation while maintaining volume data if it is needed. The proposed technique is based on grouping the marching cubes (MC) patterns into ...

    • Multiresolution volume visualitzacion with a texture-based octree 

      Boada, Imma; Navazo Álvaro, Isabel; Scopigno, Roberto (Springer, 2001)
      Article
      Accés restringit per política de l'editorial
      Although 3D texture-based volume rendering guarantees image quality almost interactively, it is difficult to maintain an interactive rate when the technique has to be exploited on large datasets. In this paper, we propose ...

    • Optimal exploitation of client texture hardware capabilities on a client-server remote visualization framework 

      Boada, Imma; Navazo Álvaro, Isabel (2003-05)
      Article
      Accés restringit per política de l'editorial
      Given a client-server communication network, with workstations equipped with 3D texture hardware, we propose a technique that guarantees the optimal use of the client texture hardware. We consider the best representation ...

    • The Hybrid Octree: towards the definition of a multiresolution hybrid framework 

      Boada, Imma; Navazo Álvaro, Isabel (2002)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The Hybrid Octree (HO) is an octree-based representation scheme for coding in a single model an exact representation of a surface and volume data. The HO is able to efficiently manipulate surface and volume data independently. ...
