    • A virtual reality front-end for city modeling 

      Randó Segura, Eduard; Andújar Gran, Carlos Antonio; Patow, Gustavo Ariel (European Association for Computer Graphics (Eurographics), 2019)
      Conference lecture
      Open Access
      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 ...
    • Estructuras geométricas jerárquicas para la modelización de escenas 3D 

      Brunet Crosa, Pere; Santisteve i Puyuelo, Francesc; Vilanova, Anna; Chiarabini, Luca; Patow, Gustavo Ariel; Staffetti, E.; Surinyac, Jordi (1999-04)
      External research report
      Open Access
      This work surveys on the principal hierarchical geometric structures used to represent 3D scenes. We also present the basic algorithms to work with them, an overview on some recent works and a comparative discussion. This ...
    • NightLighting: a nocturnal urban illumination approach 

      Muñoz Pandiella, Imanol; Andújar Gran, Carlos Antonio; Patow, Gustavo Ariel (European Association for Computer Graphics (Eurographics), 2013)
      Conference report
      Restricted access - publisher's policy
      Real time rendering of cities with realistic global illumination is still an open problem. In this paper we propose a two-step algorithm to simulate the nocturnal illumination of a city. The first step computes an approximate ...
    • Procedural semantic cities 

      Roglà Pujalt, Otger; Pelechano Gómez, Núria; Patow, Gustavo Ariel (European Association for Computer Graphics (Eurographics), 2017)
      Conference report
      Open Access
      Procedural modeling of virtual cities has achieved high levels of realism with little effort from the user. One can rapidly obtain a large city using off-the-shelf software based on procedural techniques, such as the use ...
    • R4: Realistic rain rendering in realtime 

      Creus López, Carles; Patow, Gustavo Ariel (2013-02)
      Article
      Restricted access - publisher's policy
      Realistic rain simulation is a challenging problem due to the variety of different phenomena to consider. In this paper we propose a new rain rendering algorithm that extends present state of the art in the field, achieving ...
    • Reflector design from radiance distributions 

      Patow, Gustavo Ariel; Pueyo Sandez, Francesc Xavier; Vinacua Pla, Álvaro (Institute for Applied Mathematics and Information Technology, 2004-12)
      Article
      Restricted access - publisher's policy
      This paper proposes a technique for the design of reflector shapes from prescribed optical properties (far field radiance distribution) and geometrical constraints, which is of high importance in the field of Lighting ...
    • The ViRVIG institute 

      Andújar Gran, Carlos Antonio; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau; Patow, Gustavo Ariel; Pueyo Sandez, Francesc Xavier (2011-11-16)
      Article
      Open Access
      In this paper we present the ViRVIG Institute, a recently created institution that joins two well-known research groups: MOVING in Barcelona, and GGG in Girona. Our main research topics are Virtual Reality devices and ...
