    Throughout the years, many shading techniques have been developed to improve the conveying of information in Volume Visualization. Some of these methods, usually referred to as realistic, are supposed to provide better ...
  • Inexpensive reconstruction and rendering of realistic roadside landscapes 

    Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Vico Moya, Miguel Ángel; Moya Santos, Sergio; Brunet Crosa, Pere (2014-09-01)
    Article
    Accés obert
    In this paper, we present an inexpensive approach to create highly detailed reconstructions of the landscape surrounding a road. Our method is based on a space-efficient semi-procedural representation of the terrain and ...
  • From one to many: Simulating groups of agents with reinforcement learning controllers 

    Casadiego, Luiselena; Pelechano Gómez, Núria (2015)
    Comunicació de congrés
    Accés obert
    Simulation of crowd behavior has been approached through many different methodologies, but the problem of mimicking human decisions and reactions remains a challenge for all. We propose an alternative model for simulation ...
  • Exploiting the potential of image based crowd rendering

    Per-joint impostors have been used to achieve high performance when rendering thousands of agents, while still allowing us to blend animation. This provides interactively animated crowds and reduces the memory footprint ...
  • Footstep parameterized motion blending using barycentric coordinates

    This paper presents a real-time animation system for fully embodied virtual humans that satisfies accurate foot placement constraints for different human walking and running styles. Our method offers a fine balance between ...
  • Abdominothoracic mechanisms of functional abdominal distension and correction by biofeedback 

    Barba, Elizabeth; Burri, Emanuel; Accarino Garaventa, Anna María; Cisternas, Daniel; Quiroga, Sergi; Monclús Lahoya, Eva; Navazo Álvaro, Isabel; Malagelada Benapres, Juan Ramon; Azpiroz Vidaur, Fernando (2015-04-01)
    Article
    Accés obert
    BACKGROUND & AIMS: In patients with functional gut disorders, abdominal distension has been associated with descent of the diaphragm and protrusion of the anterior abdominal wall. We investigated mechanisms of abdominal ...
  • Clearance for diversity of agents’ sizes in navigation meshes 

    Oliva Martínez, Ramon; Pelechano Gómez, Núria (2014-12-04)
    Article
    Accés restringit per política de l'editorial
    There are two frequent artifacts in crowd simulation caused by navigation mesh design. The first appears when all agents attempt to traverse the navigation mesh and share the same way points through portals, thus increasing ...
