      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 ...
    • Managing spatial selections with contextual snapshots 

      Mindek, Peter; Gröller, Eduard; Bruckner, Stefan (Peer reviewed; Journal article, 2014-12)
      Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific ...
    • MedUse: A Visual Analysis Tool for Medication Use Data in the ABCD Study 

      Bartsch, Hauke; Garrison, Laura; Bruckner, Stefan; Wang, Ariel; Tapert, Susan F.; Grüner, Renate (Peer reviewed; Journal article, 2019)
      The RxNorm vocabulary is a yearly-published biomedical resource providing normalized names for medications. It is used to capture medication use in the Adolescent Brain Cognitive Development (ABCD) study, an active and ...
    • Memento: Localized time‐warping for spatio‐temporal selection 

      Solteszova, Veronika; Smit, Noeska Natasja; Stoppel, Sergej; Grüner, Renate; Bruckner, Stefan (Peer reviewed; Journal article, 2020)
      Interaction techniques for temporal data are often focused on affecting the spatial aspects of the data, for instance through the use of transfer functions, camera navigation or clipping planes. However, the temporal aspect ...
    • Model-based Visualization for Medical Education and Training 

      Smit, Noeska Natasja; Lawonn, Kai; Kraima, Annelot; DeRuiter, Marco; Bruckner, Stefan; Eisemann, Elmar; Vilanova, Anna (Peer reviewed; Journal article, 2019)
      Anatomy, or the study of the structure of the human body, is an essential component of medical education. Certain parts of human anatomy are considered to be more complex to understand than others, due to a multitude of ...
    • Obscurance-based Volume Rendering Framework 

      Ruiz, Marc; Boada, Imma; Viola, Ivan; Bruckner, Stefan; Feixas, Miquel; Sbert, Mateu (Proceedings of Volume Graphics 2008., Conference object; Peer reviewed, 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 (Peer reviewed; Journal article, 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, ...
    • Similarity-based Exploded Views 

      Ruiz, Marc; Viola, Ivan; Boada, Imma; Bruckner, Stefan; Feixas, Miquel; Sbert, Mateu (Lecture Notes in Computer Science; 5166, Chapter; Peer reviewed, 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 ...
    • Smart Surrogate Widgets for Direct Volume Manipulation 

      Stoppel, Sergej; Bruckner, Stefan (Conference object; Peer reviewed; Journal article, 2018)
      Interaction is an essential aspect in volume visualization, yet common manipulation tools such as bounding boxes or clipping plane widgets provide rather crude tools as they neglect the complex structure of the underlying ...
