    • closedAccess   Reducing complexity in polygonal meshes with view-based saliency 

      Castelló Boscá, Pascual; Chover, Miguel; Sbert Casasayas, Mateu; Feixas, Miguel Elsevier (2014-08)
      Salient features in 3D meshes such as small high-curvature details in the middle of largely flat regions are easily ignored by most mesh simplification methods. Nevertheless, these features can be perceived by human observers ...

    • closedAccess   Simplification method for textured polygonal meshes based on structural appearance 

      González Ballester, Carlos; Castelló Boscá, Pascual; Chover, Miguel; Sbert Casasayas, Mateu; Feixas, Miguel; Gumbau Portalés, Jesús Springer-Verlag (2013-05)
      This paper proposes an image-based simplification method for textured triangle meshes that preserves the structural appearance of textured models. Models used in interactive applications are usually composed of textured ...

    • closedAccess   Smooth shadow boundaries with exponentially-warped gaussian filtering 

      Gumbau Portalés, Jesús; Sbert Casasayas, Mateu; Szirmay-Kalos, László; Chover, Miguel; González Ballester, Carlos Elsevier (2013-05)
      Shadow mapping is widely used in computer graphics for efficiently rendering shadows in real-time applications. Shadow maps cannot be filtered as regular textures, thus their limited resolution can cause severe shadow map ...

    • openAccess   Tsallis entropy for geometry simplification 

      Castelló Boscá, Pascual; González, Carlos; Sbert Casasayas, Mateu; Feixas, Miguel; Chover, Miguel MDPI Publishing (2011-09-29)
      This paper presents a study and a comparison of the use of different information-theoretic measures for polygonal mesh simplification. Generalized measures from Information Theory such as Havrda–Charva ́t–Tsallis entropy ...

    • openAccess   View-Dependent Tessellation and Simulation of Ocean Surfaces 

      Puig Centelles, Anna; Ramos, Jose Francisco; Ripollés Mateu, Oscar Enrique; Chover, Miguel; Sbert Casasayas, Mateu Hindawi Publishing Corporation (2014-02)
      Modeling and rendering realistic ocean scenes have been thoroughly investigated for many years. Its appearance has been studied and it is possible to find very detailed simulations where a high degree of realism is achieved. ...
