  • Smooth Transitioning Between two Walking Metaphors for Virtual Reality Applications 

    Salvetti, Isadora; Rios, Alex; Nuria, Pelechano (The Eurographics Association, 2019)
    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 ...
  • Prototype of an Automatic Registration System for the Remains of Archaeological Sites 

    Ruiz, José Luis López; Alvarado, Lidia Ortega; Higueruela, Francisco Ramón Feito (The Eurographics Association, 2019)
    Data acquisition in archaeological excavations is a time consuming task developed on site that must be completed later with the information stored in the database. In this paper, we introduce the work in progress for the ...
  • A Virtual Reality Front-end for City Modeling 

    Rando, Eduard; Andujar, Carlos; Patow, Gustavo A. (The Eurographics Association, 2019)
    Current tools for city modeling, including those supporting procedural techniques, have a steep learning curve and require substantial user input and/or skills to create realistic 3D models of cities. In this paper we ...
  • 3D Environment Understanding in Real-time Using Input CAD Models for AR Applications 

    Rodríguez, David Jurado; Rodríguez, Juan Manuel Jurado; Alvarado, Lidia Ortega; Higueruela, Francisco Ramón Feito (The Eurographics Association, 2019)
    The automatic recognition of real environments has become a relevant issue for multiple purposes in computer graphics, computer vision and artificial intelligence. In this work, we focus on environment understanding according ...
  • Visiting Ancient Rome with a Serious Game 

    Galí, Carlos; Remolar, Inmaculada; Rebollo, Cristina (The Eurographics Association, 2019)
    The current rise of video games has made that different fields of research feel attracted to these new technologies in order to enhance their works and make their results more attractive. It is for this reason that so-called ...
  • Multispectral Registration, Undistortion and Tree Detection for Precision Agriculture 

    Ruiz, Alfonso López; Rodríguez, Juan Manuel Jurado; Anguita, Carlos Javier Ogayar; Higueruela, Francisco Ramón Feito (The Eurographics Association, 2019)
    Multi-lens multispectral cameras allow us to record multispectral information for a whole area of terrain, even though we may only need the vegetation data. Based on the intensity of each multispectral image we can retrieve ...
  • User-reconfigurable CAD Feature Recognition in 1- and 2-topologies with Reduction of Search Space via Geometry Filters 

    Corcho, Juan Camilo Pareja; Acosta, Oscar Mauricio Betancur; Ruiz, Oscar E.; Cadavid, Carlos (The Eurographics Association, 2019)
    In the context of Computer-Aided Design and Manufacturing, the problem of feature recognition plays a key role in the integration of systems. Until now, compromises have been reached by only using FACE-based geometric ...
