    • A multi-projector CAVE system with commodity hardware and gesture-based interaction 

      Andújar Gran, Carlos Antonio; Brunet Crosa, Pere; Vinacua Pla, Álvaro; Vico Moya, Miguel Ángel; Díaz García, Jesús (2017-01-12)
      Research report
      Open Access
      Spatially-immersive systems such as CAVEs provide users with surrounding worlds by projecting 3D models on multiple screens around the viewer. Compared to alternative immersive systems such as HMDs, CAVE systems are a ...

    • Adaptive transfer functions: improved multiresolution visualization of medical models 

      Díaz García, Jesús; Brunet Crosa, Pere; Navazo Álvaro, Isabel; Pérez, Frederic; Vázquez Alcocer, Pere Pau (Springer, 2016-05-14)
      Article
      Open Access
      Medical datasets are continuously increasing in size. Although larger models may be available for certain research purposes, in the common clinical practice the models are usually of up to 512x512x2000 voxels. These ...

    • Downsampling and storage of pre-computed gradients for volume rendering 

      Díaz García, Jesús; Brunet Crosa, Pere; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2017)
      Conference report
      Open Access
      The way in which gradients are computed in volume datasets influences both the quality of the shading and the performance obtained in rendering algorithms. In particular, the visualization of coarse datasets in multi-resolution ...

    • Downsampling methods for medical datasets 

      Díaz García, Jesús; Brunet Crosa, Pere; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (IADIS Press, 2017)
      Conference report
      Open Access
      Volume visualization software usually has to deal with datasets that are larger than the GPUs may hold. This is especially true in one of the most popular application scenarios: medical visualization. Typically, medical ...

    • Feature-preserving downsampling for medical images 

      Díaz García, Jesús; Brunet Crosa, Pere; Navazo Álvaro, Isabel; Pérez, Frederic; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2015)
      Conference lecture
      Open Access
      In the medical imaging field, interactive direct volume rendering of large volume datasets is a challenging task. Multi-resolution techniques deal with this problem by downsampling the original dataset to produce coarser ...
