      Usually visualization is applied to gain insight into data. Yet consuming the data in form of visual representation is not always enough. Instead, users need to edit the data, preferably through the same means used to ...
    • Parallel Irradiance Caching for Interactive Monte-Carlo Direct Volume Rendering 

      Khlebnikov, Rostislav; Voglreiter, Philip; Steinberger, Markus; Kainz, Bernhard; Schmalstieg, Dieter (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose a technique to build the irradiance cache for isotropic scattering simultaneously with Monte Carlo progressive direct volume rendering on a single GPU, which allows us to achieve up to four times increased ...
    • Methods for Compensating Contrast Effects in Information Visualization 

      Mittelstädt, Sebastian; Stoffel, Andreas; Keim, Daniel A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Color, as one of the most effective visual variables, is used in many techniques to encode and group data points according to different features. Relations between features and groups appear as visual patterns in the ...
    • A Gaze-enabled Graph Visualization to Improve Graph Reading Tasks 

      Okoe, Mershack; Alam, Sayeed Safayet; Jianu, Radu (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Performing typical network tasks such as node scanning and path tracing can be difficult in large and dense graphs. To alleviate this problem we use eye-tracking as an interactive input to detect tasks that users intend ...
    • Visualization of Medicine Prescription Behavior 

      Corput, Paul van der; Arends, Johan; Wijk, Jarke J. van (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Medicine prescriptions play an important role in medical treatments. More insight in medicine prescription behavior can lead to more efficient and effective treatments, as well as reflection on prescription behavior for ...
    • Preface and Table of Contents 

      H. Carr, P. Rheingans, and H. Schumann (The Eurographics Association and Blackwell Publishing Ltd., 2014)
    • Extracting Features from Time-Dependent Vector Fields Using Internal Reference Frames 

      Bhatia, Harsh; Pascucci, Valerio; Kirby, Robert M.; Bremer, Peer-Timo (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Extracting features from complex, time-dependent flow fields remains a significant challenge despite substantial research efforts, especially because most flow features of interest are defined with respect to a given ...
    • 4D MRI Flow Coupled to Physics-Based Fluid Simulation for Blood-Flow Visualization 

      Hoon, Niels de; Pelt, Roy van; Jalba, Andrei; Vilanova, Anna (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Modern MRI measurements deliver volumetric and time-varying blood-flow data of unprecedented quality. Visual analysis of these data potentially leads to a better diagnosis and risk assessment of various cardiovascular ...
    • Comparative Blood Flow Visualization for Cerebral Aneurysm Treatment Assessment 

      Pelt, Roy van; Gasteiger, Rocco; Lawonn, Kai; Meuschke, Monique; Preim, Bernhard (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      A pathological vessel dilation in the brain, termed cerebral aneurysm, bears a high risk of rupture, and is associated with a high mortality. In recent years, incidental findings of unruptured aneurysms have become more ...
