    • ClustMe: A Visual Quality Measure for Ranking Monochrome Scatterplots based on Cluster Patterns 

      Abbas, Mostafa M.; Aupetit, Michaël; Sedlmair, Michael; Bensmail, Halima (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We propose ClustMe, a new visual quality measure to rank monochrome scatterplots based on cluster patterns. ClustMe is based on data collected from a human-subjects study, in which 34 participants judged synthetically ...

    • A Framework for GPU-accelerated Exploration of Massive Time-varying Rectilinear Scalar Volumes 

      Marton, Fabio; Agus, Marco; Gobbetti, Enrico (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We introduce a novel flexible approach to spatiotemporal exploration of rectilinear scalar volumes. Our out-of-core representation, based on per-frame levels of hierarchically tiled non-redundant 3D grids, efficiently ...

    • Robust Extraction and Simplification of 2D Symmetric Tensor Field Topology 

      Jankowai, Jochen; Wang, Bei; Hotz, Ingrid (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      In this work, we propose a controlled simplification strategy for degenerated points in symmetric 2D tensor fields that is based on the topological notion of robustness. Robustness measures the structural stability of the ...

    • Robust Reference Frame Extraction from Unsteady 2D Vector Fields with Convolutional Neural Networks 

      Kim, Byungsoo; Günther, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Robust feature extraction is an integral part of scientific visualization. In unsteady vector field analysis, researchers recently directed their attention towards the computation of near-steady reference frames for vortex ...

    • Scalable Ray Tracing Using the Distributed FrameBuffer 

      Usher, Will; Wald, Ingo; Amstutz, Jefferson; Günther, Johannes; Brownlee, Carson; Pascucci, Valerio (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Image- and data-parallel rendering across multiple nodes on high-performance computing systems is widely used in visualization to provide higher frame rates, support large data sets, and render data in situ. Specifically ...

    • A User-based Visual Analytics Workflow for Exploratory Model Analysis 

      Cashman, Dylan; Humayoun, Shah Rukh; Heimerl, Florian; Park, Kendall; Das, Subhajit; Thompson, John; Saket, Bahador; Mosca, Abigail; Stasko, John; Endert, Alex; Gleicher, Michael; Chang, Remco (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Many visual analytics systems allow users to interact with machine learning models towards the goals of data exploration and insight generation on a given dataset. However, in some situations, insights may be less important ...

    • Visual Analysis of Charge Flow Networks for Complex Morphologies 

      Kottravel, Sathish; Falk, Martin; Bin Masood, Talha; linares, mathieu; Hotz, Ingrid (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      In the field of organic electronics, understanding complex material morphologies and their role in efficient charge transport in solar cells is extremely important. Related processes are studied using the Ising model and ...
