    Nowadays, there are multiple available range scanning technologies which can capture extremely detailed models of realworld surfaces. The result of such process is usually a set of point clouds which can contain billions ...
  • Smooth transitioning between two walking metaphors for virtual reality applications 

    Salvetti, Isadora; Ríos Jérez, Alejandro; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2019)
    Conference report
    Open Access
    Virtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the ...
  • A Web-based application for the visual exploration of colon morphology data 

    Males, Jan; Monclús Lahoya, Eva; Díaz Iriberri, José; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2019)
    Conference report
    Open Access
    The colon is an organ whose constant motility poses difficulties to its analysis. Although morphological data can be successfully extracted from Computational Tomography, its radiative nature makes it only indicated for ...
  • Colonic content assessment from MRI imaging using a semi-automatic approach 

    Ceballos Inza, Víctor; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Bendezú García, Álvaro; Mego Silva, Marianela; Merino Casabiel, Xavier; Azpiroz Vidaur, Fernando; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2019)

    The analysis of the morphology and content of the gut is necessary in order to achieve a better understanding of its metabolic and functional activity. Magnetic resonance imaging (MRI) has become an important imaging ...
  • An automatic tool to facilitate authoring animation blending in game engines 

    Delicado Alcántara, Luis; Pelechano Gómez, Núria (Association for Computing Machinery (ACM), 2019)
    Conference report
    Open Access
    Achieving realistic virtual humans is crucial in virtual reality applications and video games. Nowadays there are software and game development tools, that are of great help to generate and simulate characters. They offer ...
  • Depth map repairing for building reconstruction 

    Andújar Gran, Carlos Antonio; Argudo Medrano, Óscar; Besora Vilardaga, Isaac; Brunet Crossa, Pere; Chica Calaf, Antonio; Comino Trinidad, Marc (European Association for Computer Graphics (Eurographics), 2018)
    Conference report
    Open Access
    Structure-from-motion along with multi-view stereo techniques jointly allow for the inexpensive scanning of 3D objects (e.g. buildings) using just a collection of images taken from commodity cameras. Despite major advances ...
  • VR-assisted architectural design in a heritage site: the Sagrada Família case study 

    Andújar Gran, Carlos Antonio; Brunet Crossa, Pere; Buxareu, Jeronimo; Fons Sánchez, Joan; Laguarda, Narcis; Pascual, Jordi; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2018)
    Conference report
    Open Access
    Virtual Reality (VR) simulations have long been proposed to allow users to explore both yet-to-built buildings in architectural design, and ancient, remote or disappeared buildings in cultural heritage. In this paper we ...
  • Users’ locomotor behavior in collaborative virtual reality 

    Ríos Jérez, Alejandro; Palomar Soler, Marc; Pelechano Gómez, Núria (Association for Computing Machinery (ACM), 2018)
    Conference report
    Restricted access - publisher's policy
    This paper presents a virtual reality experiment in which two participants share both the virtual and the physical space while performing a collaborative task. We are interested in studying what are the differences in human ...
  • Rendering and interacting with volume models in inmmersive environments 

    Fons, Joan; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2018)
    Conference report
    Open Access
    The recent advances in VR headsets, such as the Oculus Rift or HTC Vive, at affordable prices offering a high resolution display, has empowered the development of immersive VR applications. Unfortunately, the rendering ...
