  • Structural stability of planar bimodal linear systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (2014-01-01)
    Artículo
    Acceso abierto
    Structural stability ensures that the qualitative behavior of a system is preserved under small perturbations. We study it for planar bimodal linear dynamical systems, that is, systems consisting of two linear dynamics ...
  • Robust treatment of degenerate elements in interactive corotational FEM simulations

    We address the problem of robust and efficient treatment of element collapse and inversion in corotational FEM simulations of deformable objects in two and three dimensions, and show that existing degeneration treatment ...
  • Anisomorphic ray-casting manipulation for interacting with 2D GUIs 

    Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (2007-01)
    Artículo
    Acceso abierto
    The accommodation of conventional 2D GUIs with virtual environments (VEs) can greatly enhance the possibilities of many VE applications. In this paper we present a variation of the well-known ray-casting technique for fast ...

  • Interactive visualization of medical volume models in mobile devices 

    Campoalegre, Lázaro; Brunet Crosa, Pere; Navazo Álvaro, Isabel (2013-10)
    Artículo
    Acceso restringido por política de la editorial
    Interactive visualization of volume models in standard mobile devices is a challenging present problem with increasing interest from new application fields like telemedicine. The complexity of present volume models in ...
  • Adaptive cross-sections of anatomical models

    Artículo
    Acceso restringido por política de la editorial
    Medical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ...
  • Mechanisms of abdominal distension in severe intestinal dysmotility: abdomino-thoracic response to gut retention 

    Barba, Elisabeth; Quiroga, Santi; Accarino, Anna; Monclús Lahoya, Eva; Malagelada, C; Burri, E; Navazo Álvaro, Isabel; Malagelada, J; Azpiroz, Fernando (2013)
    Artículo

    BACKGROUND: We previously showed that abdominal distension in patients with functional gut disorders is due to a paradoxical diaphragmatic contraction without major increment in intraabdominal volume. Our aim was to ...
  • The ViRVIG institute 

    Andújar Gran, Carlos Antonio; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau; Patow, Gustavo; Pueyo, Xavier (2011-11-16)
    Artículo
    Acceso abierto
    In this paper we present the ViRVIG Institute, a recently created institution that joins two well-known research groups: MOVING in Barcelona, and GGG in Girona. Our main research topics are Virtual Reality devices and ...
  • Avatar locomotion in crowd simulation 

    Pelechano Gómez, Núria; Spanlang, Bernhard; Beacco Porres, Alejandro (2011-03)
    Artículo
    Acceso restringido por política de la editorial
    This paper presents an Animation Planning Mediator (APM) designed to synthesize animations efficiently for virtual characters in real time crowd simulation. From a set of animation clips, the APM selects the most appropriate ...
  • Efficient rendering of animated characters through optimized per-joint impostors 

    Beacco Porres, Alejandro; Andújar Gran, Carlos Antonio; Pelechano Gómez, Núria; Spanlang, Bernhard (2012-02)
    Artículo
    Acceso restringido por política de la editorial
    In this paper, we present a new impostor-based representation for 3D animated characters supporting real-time rendering of thousands of agents. We maximize rendering performance by using a collection of pre-computed ...
  • Hybrid Rugosity Mesostructures (HRMs) for fast and accurate rendering of fine haptic detail 

    Theoktisto, Víctor; Fairén González, Marta; Navazo Álvaro, Isabel (Centro Latinoamericano de Estudios en Informática, 2010)
    Artículo
    Acceso abierto
    The haptic rendering of surface mesostructure (fine relief features) in dense triangle meshes requires special structures, equipment, and high sampling rates for detailed perception of rugged models. Low cost approaches ...
  • World-in-miniature interaction for complex virtual environments 

    Trueba Hornero, Ramón; Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (IGI Global, 2010-12)
    Artículo
    Acceso abierto
    Object occlusion is a major handicap for efficient interaction with 3D virtual environments. The well-known World in Miniature (WIM) metaphor partially solves this problem by providing an additional dynamic view point ...
