    • Tracking for Virtual Environment using Kinect 

      Sánchez, M. García; Salas, A. León; Cantero, J. C. Torres (The Eurographics Association, 2012)
      Los sistemas de tracking magnético suelen tener alcance limitado y presenta problemas de interferencias. En este trabajo proponemos utilizar los sensores de kinect para realizar el tracking en sistemas HMD.
    • Generating Coherent Ray Directions in Path Tracing 

      Torres, Roberto; Martín, Pedro J.; Gavilanes, Antonio (The Eurographics Association, 2012)
      The quality of the images produced by a global illumination rendering engine is highly connected to the number of paths that are randomly generated from the camera to the light sources. Graphics Processing Units (GPUs) ...
    • A Procedural Modeling System for the Creation of Huge Models 

      Cubero, Francisco; Mas, Albert; Patow, Gustavo (The Eurographics Association, 2012)
      This paper presents a new general purpose procedural geometrical modeling system. It is focused on providing flexibility, modularity and scalability. Furthermore, it is taylored to manage huge geometric models, with millions ...
    • Evaluating Three Versions of an Augmented Reality Mobile Game about Recycling
