• openAccess   Design of a multiuser virtual trade fair using a game engine 

      Remolar, Inmaculada; Chover, Miguel; Quirós Bauset, Ricardo; Gumbau Portalés, Jesús; Castelló Boscá, Pascual; Rebollo Santamaría, Cristina; Ramos, Jose Francisco Springer (2011)
      The current world economic situation makes it necessary to develop new ways of establishing commercial relationships. One possible solution is to explore the advantages of virtual worlds, and for this reason online virtual ...
    • openAccess   Information theory tools for viewpoint selection, mesh saliency and geometry simplification 

      Sbert Casasayas, Mateu; Feixas, Miguel; Castelló Boscá, Pascual; Chover, Miguel Springer (2009)
      In this chapter we review the use of an information channel as a unified framework for viewpoint selection, mesh saliency and geometry simplification. Taking the viewpoint distribution as input and object mesh polygons as ...
    • 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 ...
    • 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 ...
    • closedAccess   Viewpoint-based simplification using f-divergences 

      Castelló Boscá, Pascual; Sbert Casasayas, Mateu; Chover, Miguel; Feixas, Miguel Elsevier (2008)
      We propose a new viewpoint-based simplification method for polygonal meshes, driven by several f-divergences such as Kullback-Leibler, Hellinger and Chi-Square. These distances are a measure of discrimination between ...
    • closedAccess   Viewpoint-driven simplification using mutual information 

      Castelló Boscá, Pascual; Sbert Casasayas, Mateu; Chover, Miguel; Feixas, Miguel Elsevier (2008)
      In this paper, a new viewpoint-based simplification approach is proposed for polygonal meshes. This approach is driven by an information-theoretic measure, viewpoint mutual information. Our algorithm applies the best ...
