  • Structural stability of planar bimodal linear systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (2014-01-01)
    Article
    Open Access
    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 

    Civit Flores, Oscar; Susín Sánchez, Antonio (2014-09-01)
    Article
    Restricted access - publisher's policy
    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 ...
  • Coupling camera-tracked humans with a simulated virtual crowd 

    Rivalcoba, Jorge Ivan; De Gyves, Oriam; Rudomin, Isaac; Pelechano Gómez, Núria (SciTePress, 2014)
    Conference report
    Open Access
    Our objective with this paper is to show how we can couple a group of real people and a simulated crowd of virtual humans. We attach group behaviors to the simulated humans to get a plausible reaction to real people. We ...
  • CAVAST: The crowd animation, visualization, and simulation testbed 

    Beacco Porres, Alejandro; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2014)
    Conference report
    Restricted access - publisher's policy
    Simulation, animation and rendering of crowds has become an important part of real-time applications such as videogames. Virtual environments achieve higher realism when being populated by virtual crowds as opposed to ...
  • Data-aware picking for medical models 

    Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Navazo Álvaro, Isabel (Springer, 2014-09-30)
    Part of book or chapter of book
    Open Access
    Medical doctors are often faced with the problem of selecting anchoring points in 3D space. These points are commonly used for measurement tasks, such as lengths of bones, or dimensions of pathological structures (e.g. ...
  • Anisomorphic ray-casting manipulation for interacting with 2D GUIs 

    Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (2007-01)
    Article
    Open Access
    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 ...
  • Contenido colónico fisiológico medido por resonancia magnética 

    Bendezú, Álvaro; Merino, Xavi; Accarino Garaventa, Anna María; Monclús Lahoya, Eva; Navazo Álvaro, Isabel; Azpiroz Vidaur, Fernando (2014-03)

  • NightLighting: a nocturnal urban illumination approach 

    Muñoz Pandiella, Imanol; Andújar Gran, Carlos Antonio; Patow, Gustavo (European Association for Computer Graphics (Eurographics), 2013)
    Conference report
    Restricted access - publisher's policy
    Real time rendering of cities with realistic global illumination is still an open problem. In this paper we propose a two-step algorithm to simulate the nocturnal illumination of a city. The first step computes an approximate ...
  • Interactive visualization of medical volume models in mobile devices 

    Campoalegre, Lázaro; Brunet Crosa, Pere; Navazo Álvaro, Isabel (2013-10)
    Article
    Restricted access - publisher's policy
    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 ...
  • A generalized exact arbitrary clearance technique for navigation meshes 

    Oliva Martínez, Ramon; Pelechano Gómez, Núria (ACM, 2013)
    Conference report
    Open Access
    There are two frequent artifacts in crowd simulation, the first one appears when all agents attempt to traverse the navigation mesh sharing the same way point over portals, increasing the probability of collision against ...
