      Fanni, Filippo A.; Cherchi, Gianmarco; Scateni, Riccardo (The Eurographics Association, 2017)
      In recent years, fabrication technologies developed at a very fast pace. However, some limitations on shape and dimension still apply both to additive and subtractive manufacturing, and one way to bypass them could be the ...
    • Polynomial Approximation of Blinn-Phong Model 

      Öztürk, Aydin; Bilgili, Ahmet; Kurt, Murat (The Eurographics Association, 2006)
      The Phong model has been one of the oldest and the most popular reflection models in Computer Graphics. It can be used to model specular highlights of various materials. In this paper, we consider a polynomial model and ...
    • Population Dynamics Visualization 

      Lozano, Miguel; García-Fernández, Ignacio; Orduña, Juan Manuel (The Eurographics Association, 2012)
      In this work we present a graphic, interactive system to validate population dynamics models through hypothesis (simulation results) and radiocarbon samples selection and process. The goal of the graphical tool is to allow ...
    • 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 ...
