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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
