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. ... -
Técnicas de aceleración para el método de radiosidad jerárquica
Padrón, Emilio J. (2006)[Resumen] Uno de los métodos que mejor modelan el comportamiento real de la luz en la búsqueda del realismo visual en imágenes construidas de forma sintética es el método de radiosidad. Este método presenta, sin ...
