      We present a method for constructing a surface mesh filling gaps between the boundaries of multiple disconnected input components. Unlike previous works, our method pays special attention to preserving both the connectivity ...
    • A Psychophysical Analysis of Fabricated Anisotropic Appearance 

      Filip, Jiri; Kolafová, Martina; Vávra, Radomir (The Eurographics Association, 2019)
      Many materials change surface appearance when observed for fixed viewing and lighting directions while rotating around its normal. Such distinct anisotropic behavior manifests itself as changes in textural color and ...

      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 ...
    • Visual Analysis of Probabilistic Infection Contagion in Hospitals 

      Wunderlich, Marcel; Block, Isabelle; Landesberger, Tatiana von; 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 ...
