    • Continuous Levels-of-Detail and Visual Abstraction for Seamless Molecular Visualization 

      Parulek, Julius; Jönsson, Daniel; Ropinski, Timo; Bruckner, Stefan; Ynnerman, Anders; Viola, Ivan (Wiley, 2014-05-06)
      Molecular visualization is often challenged with rendering of large molecular structures in real time. We introduce a novel approach that enables us to show even large protein complexes. Our method is based on the ...

    • A Hierarchical Splitting Scheme to Reveal Insight into Highly Self-Occluded Integral Surfaces 

      Brambilla, Andrea; Viola, Ivan; Hauser, Helwig (Václav Skala - UNION Agency, 2012)
      In flow visualization, integral surfaces are of particular interest for their ability to describe trajectories of massless particles. In areas of swirling motion, integral surfaces can become very complex and difficult ...

    • Hybrid visibility compositing and masking for illustrative rendering 

      Bruckner, Stefan; Rautek, Peter; Viola, Ivan; Roberts, Mike; Sousa, Mario Costa; Gröller, M. Eduard (Elsevier, 2010-08)
      In this paper, we introduce a novel framework for the compositing of interactively rendered 3D layers tailored to the needs of scientific illustration. Currently, traditional scientific illustrations are produced in a ...

    • Illustrative Flow Visualization: State of the Art, Trends and Challenges 

      Brambilla, Andrea; Carnecky, Robert; Peikert, Robert; Viola, Ivan; Hauser, Helwig (The Eurographics Association, 2012)
      Flow visualization is a well established branch of scientific visualization and it currently represents an invaluable resource to many fields, like automotive design, meteorology and medical imaging. Thanks to the ...

    • Interactively illustrating polymerization using three-level model fusion 

      Kolesar, Ivan; Parulek, Julius; Viola, Ivan; Bruckner, Stefan; Stavrum, Anne-Kristin; Hauser, Helwig (BioMed Central, 2014-10-14)
      Background: Research in cell biology is steadily contributing new knowledge about many aspects of physiological processes, both with respect to the involved molecular structures as well as their related function. Illustrations ...

    • Obscurance-based Volume Rendering Framework 

      Ruiz, Marc; Boada, Imma; Viola, Ivan; Bruckner, Stefan; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2008)
      lighting effects in a faster way than global illumination. Its application in volume visualization is of special interest since it permits us to generate a high quality rendering at a low cost. In this paper, we propose ...

    • Output-Sensitive Filtering of Streaming Volume Data 

      Šoltészová, Veronika; Birkeland, Åsmund; Stoppel, Sergej; Viola, Ivan; Bruckner, Stefan (John Wiley & Sons Ltd, 2016-02)
      Real-time volume data acquisition poses substantial challenges for the traditional visualization pipeline where data enhancement is typically seen as a pre-processing step. In the case of 4D ultrasound data, for instance, ...

    • Perceptually Uniform Motion Space 

      Birkeland, Åsmund; Turkay, Cagatay; Viola, Ivan (IEEE, 2014-05-07)
      Flow data is often visualized by animated particles inserted into a flow field. The velocity of a particle on the screen is typically linearly scaled by the velocities in the data. However, the perception of velocity ...

    • Similarity-based Exploded Views 

      Ruiz, Marc; Viola, Ivan; Boada, Imma; Bruckner, Stefan; Feixas, Miquel; Sbert, Mateu (Springer, 2008)
      Exploded views are often used in illustration to overcome the problem of occlusion when depicting complex structures. In this paper, we propose a volume visualization technique inspired by exploded views that partitions ...

    • Visual Cavity Analysis in Molecular Simulations 

      Parulek, Julius; Turkay, Cagatay; Reuter, Nathalie; Viola, Ivan (BioMed Central, 2013-11-12)
      Molecular surfaces provide a useful mean for analyzing interactions between biomolecules; such as identification and characterization of ligand binding sites to a host macromolecule. We present a novel technique, which ...
