      In radiotherapy, tumors are irradiated with a high dose, while surrounding healthy tissues are spared. To quantify the probability that a tumor is effectively treated with a given dose, statistical models were built and ...
    • Critical Points of Gaussian-Distributed Scalar Fields on Simplicial Grids 

      Liebmann, Tom; Scheuermann, Gerik (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Simulations and measurements often result in scalar fields with uncertainty due to errors or output sensitivity estimates. Methods for analyzing topological features of such fields usually are not capable of handling all ...
    • Exploratory Visual Analysis for Animal Movement Ecology 

      Slingsby, Aidan; Loon, Emiel van (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Movement ecologists study animals' movement to help understand their behaviours and interactions with each other and the environment. Data from GPS loggers are increasingly important for this. These data need to be processed, ...
    • Similarity Voting based Viewpoint Selection for Volumes 

      Tao, Yubo; Wang, Qirui; Chen, Wei; Wu, Yingcai; Lin, Hai (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Previous viewpoint selection methods in volume visualization are generally based on some deterministic measures of viewpoint quality. However, they may not express the familiarity and aesthetic sense of users for features ...
    • Pathfinder: Visual Analysis of Paths in Graphs 

      Partl, Christian; Gratzl, Samuel; Streit, Marc; Wassermann, Anne-Mai; Pfister, Hanspeter; Schmalstieg, Dieter; Lex, Alexander (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The analysis of paths in graphs is highly relevant in many domains. Typically, path-related tasks are performed in node-link layouts. Unfortunately, graph layouts often do not scale to the size of many real world networks. ...
    • Visual Analysis of Defects in Glass Fiber Reinforced Polymers for 4DCT Interrupted In situ Tests 

      Amirkhanov, Alexander; Amirkhanov, Artem; Salaberger, Dietmar; Kastner, Johann; Gröller, Eduard; Heinzl, Christoph (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Material engineers use interrupted in situ tensile testing to investigate the damage mechanisms in composite materials. For each subsequent scan, the load is incrementally increased until the specimen is completely fractured. ...
    • Visual Debugging Techniques for Reactive Data Visualization 

      Hoffswell, Jane; Satyanarayan, Arvind; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Interaction is critical to effective visualization, but can be difficult to author and debug due to dependencies among input events, program state, and visual output. Recent advances leverage reactive semantics to support ...
    • Using Visualization to Explore Original and Anonymized LBSN Data 

      Tarameshloo, Ebrahim; Loorak, Mona Hosseinkhani; Fong, Philip W. L.; Carpendale, Sheelagh (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present GSUVis, a visualization tool designed to provide better understanding of location-based social network (LBSN) data. LBSN data is one of the most important sources of information for transportation, marketing, ...
    • Exploring Items and Features with IF,FI-Tables 

      Corput, Paul van der; Wijk, Jarke J. van (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The exploration of high-dimensional data is challenging because humans have difficulty to understand more than three dimensions. We present a new visualization concept that enables users to explore such data and, specifically, ...
    • Time-Series Plots Integrated in Parallel-Coordinates Displays 

      Gruendl, Henning; Riehmann, Patrick; Pausch, Yves; Froehlich, Bernd (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a natural extension of two-dimensional parallel-coordinates plots for revealing relationships in time-dependent multi-attribute data by building on the idea that time can be considered as the third dimension. A ...
    • Arcs, Angles, or Areas: Individual Data Encodings in Pie and Donut Charts 

      Skau, Drew; Kosara, Robert (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Pie and donut charts have been a hotly debated topic in the visualization community for some time now. Even though pie charts have been around for over 200 years, our understanding of the perceptual factors used to read ...
    • Enhancing Scatterplots with Multi-Dimensional Focal Blur 

      Staib, Joachim; Grottel, Sebastian; Gumhold, Stefan (The Eurographics Association and John Wiley & Sons Ltd., 2016)

    • Source Inversion by Forward Integration in Inertial Flows 

      Günther, Tobias; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Inertial particles are finite-sized objects traveling with a certain velocity that differs from the underlying carrying flow, i.e., they are mass-dependent and subject to inertia. Their backward integration is in practice ...
