      Verhoeven, Floor; Sorkine-Hornung, Olga (The Eurographics Association, 2019)
      User interfaces for 3D shape modeling in Virtual Reality (VR), unlike basic tasks such as text input and item selection, have been less explored in research so far. Shape modeling in 3D lends itself very well to VR, since ...

    • Visual Analytics of Simulation Ensembles for Network Dynamics 

      Ngo, Quynh Quang; Hütt, Marc-Thorsten; Linsen, Lars (The Eurographics Association, 2019)
      A central question in the field of Network Science is to analyze the role of a given network topology on the dynamical behavior captured by time-varying simulations executed on the network. These dynamical systems are also ...
    • VMV 2019: Frontmatter 

      Schulz, Hans-Jörg; Teschner, Matthias; Wimmer, Michael (Eurographics Association, 2019)
    • Clustering Ensembles of 3D Jet-Stream Core Lines 

      Kern, Michael; Westermann, Rüdiger (The Eurographics Association, 2019)
      The extraction of a jet-stream core line in a wind field results in many disconnected line segments of arbitrary topology. In an ensemble of wind fields, these structures show high variation, coincide only partly, and ...
    • Reflection Symmetry in Textured Sewing Patterns 

      Wolff, Katja; Herholz, Philipp; Sorkine-Hornung, Olga (The Eurographics Association, 2019)
      Recent work in the area of digital fabrication of clothes focuses on repetitive print patterns, specifically the 17 wallpaper groups, and their alignment along garment seams. While adjusting the underlying sewing patterns ...
    • Cluster-based Analysis of Multi-Parameter Distributions in Cloud Simulation Ensembles 

      Kumpf, Alexander; Stumpfegger, Josef; Westermann, Rüdiger (The Eurographics Association, 2019)
      The proposed approach enables a comparative visual exploration of multi-parameter distributions in time-varying 3D ensemble simulations. To investigate whether dominant trends in such distributions occur, we consider the ...
    • Consistent Filtering of Videos and Dense Light-Fields Without Optic-Flow 

      Shekhar, Sumit; Semmo, Amir; Trapp, Matthias; Tursun, Okan; Pasewaldt, Sebastian; Myszkowski, Karol; Döllner, Jürgen (The Eurographics Association, 2019)
      A convenient post-production video processing approach is to apply image filters on a per-frame basis. This allows the flexibility of extending image filters-originally designed for still images-to videos. However, per-image ...
    • Visual Analysis of Probabilistic Infection Contagion in Hospitals 

      Wunderlich, Marcel; Block, Isabelle; von Landesberger, Tatiana; Petzold, Markus; Marschollek, Michael; Scheithauer, Simone (The Eurographics Association, 2019)
      Clinicians and hygienists need to know how an infection of one patient could be transmitted among other patients in the hospital (e.g., to prevent outbreaks). They need to analyze how many and which patients will possibly ...
    • A Visual Analytics Tool for Cohorts in Motion Data 

      Sheharyar, Ali; Ruh, Alexander; Valkov, Dimitar; Markl, Michael; Bouhali, Othmane; Linsen, Lars (The Eurographics Association, 2019)
      Motion data are curves over time in a 1D, 2D, or 3D space. To analyze sets of curves, machine learning methods can be applied to cluster them and detect outliers. However, often metadata or prior knowledge of the analyst ...
    • Joint Schedule and Layout Autotuning for Sparse Matrices with Compound Entries on GPUs 

      Mueller-Roemer, Johannes Sebastian; Stork, André; Fellner, Dieter W. (The Eurographics Association, 2019)
      Large sparse matrices with compound entries, i.e., complex and quaternionic matrices as well as matrices with dense blocks, are a core component of many algorithms in geometry processing, physically based animation, and ...
