    • Ocupado: Visualizing Location-Based Counts Over Time Across Buildings 

      Oppermann, Michael; Munzner, Tamara (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Understanding how spaces in buildings are being used is vital for optimizing space utilization, for improving resource allocation, and for the design of new facilities. We present a multi-year design study that resulted ...
    • Representative Isovalue Detection and Isosurface Segmentation Using Novel Isosurface Measures 

      Wang, Cuilan (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Interval volume is the volume of the region between two isosurfaces. This paper proposes a novel measure, called VOA measure, that is computed based on interval volume and isosurface area. This measure represents the rate ...
