    • Constructing Isosurfaces with Sharp Edges and Corners using Cube Merging 

      Bhattacharya, Arindam; Wenger, Rephael (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      A number of papers present algorithms to construct isosurfaces with sharp edges and corners from hermite data, i.e. the exact surface normals at the exact intersection of the surface and grid edges. We discuss some fundamental ...

    • Interactive Extraction and Tracking of Biomolecular Surfaces Features 

      Krone, Michael; Reina, Guido; Schulz, Christoph; Kulschewski, Tobias; Pleiss, Jürgen; Ertl, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a coordinated-view application for the analysis of molecular surface features like cavities, channels and pockets. Our tool employs object-space ambient occlusion for the detection of such features and tracks ...

    • Towards Multifield Scalar Topology Based on Pareto Optimality 

      Huettenberger, Lars; Heine, Christian; Carr, Hamish; Scheuermann, Gerik; Garth, Christoph (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      How can the notion of topological structures for single scalar fields be extended to multifields? In this paper we propose a definition for such structures using the concepts of Pareto optimality and Pareto dominance. Given ...

    • Visualizing Robustness of Critical Points for 2D Time-Varying Vector Fields 

      Wang, Bei; Rosen, Paul; Skraba, Primoz; Bhatia, Harsh; Pascucci, Valerio (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Analyzing critical points and their temporal evolutions plays a crucial role in understanding the behavior of vector fields. A key challenge is to quantify the stability of critical points: more stable points may represent ...
