    • An out-of-core method for GPU image mapping on large 3D scenarios of the real world 

      Jurado, Juan M.; Padrón, Emilio J.; Jiménez, J. Roberto; Ortega, Lidia (Elsevier, 2022)
      [Abstract] Image mapping on 3D huge scenarios of the real world is one of the most fundamental and computational expensive processes for the integration of multi-source sensing data. Recent studies focused on the observation ...

    • Efficient Culling Techniques for Interactive Deformable NURBS Surfaces on GPU 

      Concheiro, Raquel; Amor, Margarita; Padrón, Emilio J.; Doggett, Michael (SciTePress, 2016-02)
      [Abstrtact] InfoValue: NURBS (Non-uniform rational B-splines) surfaces are the standard freeform representation in Computer-Aided Design (CAD) applications. Rendering NURBS surfaces accurately while they are interactively ...

    • Free adaptive tessellation strategy of bézier surfaces 

      Concheiro, Raquel; Amor, Margarita; Bóo, Montserrat; Padrón, Emilio J. (SciTePress, 2014-01)
      [Abstract] Rendering of Bézier surfaces is currently performed by tessellating the model on the GPU and rendering the highly detailed triangle mesh. Whereas non-adaptive strategies apply the same tessellation pattern to ...

    • In-Transit Molecular Dynamics Analysis with Apache Flink 

      Zamúz, Henrique C.; Raffin, Bruno; Mures, Omar A.; Padrón, Emilio J. (Association for Computing Machinery (ACM), 2018-11)
      [Abstract] In this paper, an on-line parallel analytics framework is proposed to process and store in transit all the data being generated by a Molecular Dynamics (MD) simulation run using staging nodes in the same cluster ...

    • Interactive Rendering of NURBS Surfaces 

      Concheiro, Raquel; Amor, Margarita; Padrón, Emilio J.; Doggett, Michael (Pergamon Press, 2014)
      [Abstract] NURBS (Non-uniform rational B-splines) surfaces are one of the most useful primitives employed for high quality modeling in CAD/CAM tools and graphics software. Since direct evaluation of NURBS surfaces on the ...

    • Parallel Hierarchical Radiosity on Hybrid Platforms 

      Padrón, Emilio J.; Amor, Margarita; Bóo, Montserrat; Doallo, Ramón; Rodríguez, Gabriel (Springer Verlag, 2011-12)
      [Abstract] Achieving an efficient realistic illumination is an important aim of research in computer graphics. In this paper a new parallel global illumination method for hybrid systems based on the hierarchical radiosity ...

    • Rendering of Bézier Surfaces on Handheld Devices 

      Concheiro, Raquel; Amor, Margarita; Padrón, Emilio J.; Gil, Marisa; Martorell, Xavier (Vaclav Skala - Union Agency, 2013)
      [Abstract] Bézier surfaces have been widely employed in the designing of complex scenes with high-quality results. Nevertheless, parametric surfaces cannot be directly rendered in the current GPUs of modern handheld devices. ...

    • Synthesis of Multiresolution Scenes with Global Illumination on a GPU 

      Concheiro, Raquel; Amor, Margarita; Bóo, Montserrat; Iglesias, Iago; Padrón, Emilio J.; Doallo, Ramón (SciTePress, 2012-02)
      [Abstract] The radiosity computation has the important feature of producing view independent results, but these results are mesh dependent and, in consequence, are attached to a specific level of detail in the input mesh. ...
