  • 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 

    Civit Flores, Oscar; Susín Sánchez, Antonio (2014-09-01)

    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)
    Texto en actas de congreso
    Acceso abierto
    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)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    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)
    Capítulo de libro
    Acceso abierto
    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)
    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 ...

  • NightLighting: a nocturnal urban illumination approach 

    Muñoz Pandiella, Imanol; Andújar Gran, Carlos Antonio; Patow, Gustavo (European Association for Computer Graphics (Eurographics), 2013)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    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)
    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 ...
  • A generalized exact arbitrary clearance technique for navigation meshes 

    Oliva Martínez, Ramon; Pelechano Gómez, Núria (ACM, 2013)
    Texto en actas de congreso
    Acceso abierto
    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 ...
  • Introductory graphics for very diverse audiences 

    Fairén González, Marta; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2013)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    This paper presents our first experience teaching WebGL in a master’s degree for a class of students with very different backgrounds. The main challenge was to prepare a course that would be engaging for students with ...
  • Structural stability of planar bimodal linear systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (American Institute of Physics (AIP), 2013)
    Texto en actas de congreso
    Acceso abierto
    We consider bimodal linear dynamical systems consisting of two linear dynamics acting on each side of a given hyperplane, assuming continuity along the separating hyperplane. Focusing in the planar case, we describe which ...
