    • On Estimating the Effectiveness of Temporal and Spatial Coherence in Parallel Ray Tracing 

      Cosenza, Biagio; Cordasco, Gennaro; Chiara, Rosario De; Erra, Ugo; Scarano, Vittorio (The Eurographics Association, 2008)
      In this paper we estimate the effectiveness of exploiting coherence in Parallel Ray Tracing. We present a load- balancing technique which divides the original rendering problem in balanced subtasks and distribute them to ...

    • Practical and Robust MLS-based Integration of Scanned Data 

      Fiorin, Valentino; Cignoni, Paolo; Scopigno, Roberto (The Eurographics Association, 2008)
      The paper proposes a set of techniques for improving the quality of MLS surfaces reconstructed from point clouds that are composed by the union of many scanned range maps. The main idea of those techniques is that the ...

    • A Survey on Exploiting Grids for Ray Tracing 

      Cosenza, Biagio (The Eurographics Association, 2008)
      Grid is one of the first data structure introduced at the very beginning of computer graphics. Grids are used in several applications of computer graphics, especially in rendering algorithms. Lately, in ray tracing dynamic ...

    • Topological Operations on Triangle Meshes Using the OpenMesh Library 

      Guggeri, Fabio; Marras, Stefano; Mura, Claudio; Scateni, Riccardo (The Eurographics Association, 2008)
      Recent advances in acquisition and modelling techniques led to generating an exponentially increasing amount of 3D shapes available both over the Internet or in specific databases. While the number grows it becomes more ...

    • Towards Advanced Volumetric Display of the Human Musculoskeletal System 

      Agus, Marco; Giachetti, Andrea; Gobbetti, Enrico; Guitián, José Antonio Iglesias; Marton, Fabio (The Eurographics Association, 2008)
      We report on our research results on effective volume visualization techniques for medical and anatomical data. Our volume rendering approach employs GPU accelerated out-of-core direct rendering algorithms to fully support ...

    • A Virtual-Reality-based Evaluation Environment for Wheelchair-mounted Manipulators 

      Santis, Agostino De; Gironimo, Giuseppe Di; Marzano, Adelaide; Siciliano, Bruno; Tarallo, Andrea (The Eurographics Association, 2008)
      The design of solutions for robotic extenders of wheelchairs must take into account both objective and subjective metrics for everyday activities in human environments. Virtual Reality (VR) constitutes a useful tool to ...
