      The sensorization of virtual tv sets using motion capture systems allows the automation of many of the processes implied in the live broadcast of a tv show. It facilitates the tasks of both the actor (allowing him to ...

    • Design of an Information System for Cultural Heritage 

      Soler, Francisco; Torres, Juan Carlos; León, Alejandro J.; Luzon, M. Victoria (The Eurographics Association, 2012)
      Usually the information that must be managed by archaeologist for any cultural heritage artefact is very heterogeneous. Due to its spatial nature this information cannot be easily represented with conventional data management ...

    • Differential Ray Marching 

      Muñoz, Adolfo (The Eurographics Association, 2012)
      Several participating media rendering algorithms are based on ray marching: they integrate the variations of radiance along the volume covered by the participating media by splitting the path of light into segments and ...

    • Evaluating Three Versions of an Augmented Reality Mobile Game about Recycling 

      Furió, D.; Juan, M.-Carmen; Alem, L.; Ashworth, P. (The Eurographics Association, 2012)
      We present three versions of an Augmented Reality (AR) game (basic, collaborative and competitive) for changing people attitudes with regard to climate change. We present a study in which twenty-eight primary school students ...

    • From the Patient to the Surgery - A Complete Computer Vision and Graphics Process 

      Martinez, A.; Jimenez, J. (The Eurographics Association, 2012)
      Generating digital information ready to use on a surgery operation from a patient is a complex process. This process involves computer vision techniques, in order to extract digital information from medical images, and ...

    • 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) ...
