    • Topological Landscape Ensembles for Visualization of Scalar-Valued Functions 

      Harvey, William; Wang, Yusu (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Visual representation techniques enable perception and exploration of scientific data. Following the topological landscapes metaphor ofWeber et al., we provide a new algorithm for visualizing scalar functions defined on ...
    • Matrix Trees 

      Andrysco, Nathan; Tricoche, Xavier (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We propose a new data representation for octrees and kd-trees that improves upon memory size and algorithm speed of existing techniques. While pointerless approaches exploit the regular structure of the tree to facilitate ...
    • Coherent Culling and Shading for Large Molecular Dynamics Visualization 

      Grottel, Sebastian; Reina, Guido; Dachsbacher, Carsten; Ertl, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Molecular dynamics simulations are a principal tool for studying molecular systems. Such simulations are used to investigate molecular structure, dynamics, and thermodynamical properties, as well as a replacement for, or ...
    • The Perception of Correlation in Scatterplots

    • Scalable Multi-view Registration for Multi-Projector Displays on Vertically Extruded Surfaces 

      Sajadi, Behzad; Majumder, Aditi (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Recent work have shown that it is possible to register multiple projectors on non-planar surfaces using a single uncalibrated camera instead of a calibrated stereo pair when dealing with a special class of non-planar ...
    • Topology Aware Stream Surfaces 

      Schneider, Dominic; Reich, Wieland; Wiebel, Alexander; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present an algorithm that allows stream surfaces to recognize and adapt to vector field topology. Standard stream surface algorithms either refine the surface uncontrolled near critical points which slows down the ...
    • Hardware-Assisted Projected Tetrahedra 

      Maximo, André; Marroquim, Ricardo; Farias, Ricardo (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present a flexible and highly efficient hardware-assisted volume renderer grounded on the original Projected Tetrahedra (PT) algorithm. Unlike recent similar approaches, our method is exclusively based on the rasterization ...
    • Multi-layer Depth Peeling by Single-Pass Hardware Rasterisation for Faster Isosurface Raytracing on a GPU 

      Liu, Baoquan; Clapworthy, Gordon J.; Dong, Feng (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Empty-space skipping is an essential acceleration technique for volume rendering. Image-order empty-space skipping is not well suited to GPU implementation, since it must perform checks on, essentially, a per-sample basis, ...
    • Reusable Visualizations and Animations for Surgery Planning 

      Mühler, Konrad; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      For surgical planning, the exploration of 3D visualizations and 2D slice views is essential. However, the generation of visualizations which support the specific treatment decisions is very tedious. Therefore, the reuse ...
    • Video Visualization for Snooker Skill Training 

      Höferlin, Markus; Grundy, Edward; Borgo, Rita; Weiskopf, Daniel; Chen, Min; Griffiths, Iwan W.; Griffiths, W. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present a feasibility study on using video visualization to aid snooker skill training. By involving the coaches and players in the loop of intelligent reasoning, our approach addresses the difficulties of automated ...
    • Visual Analysis of Multi-Joint Kinematic Data 

      Krekel, Peter R.; Valstar, Edward R.; Groot, Jurriaan de; Post, Frits H.; Nelissen, Rob G. H. H.; Botha, Charl P. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Kinematics is the analysis of motions without regarding forces or inertial effects, with the purpose of understanding joint behaviour. Kinematic data of linked joints, for example the upper extremity, i.e. the shoulder and ...
    • Accelerated Visualization of Dynamic Molecular Surfaces 

      Lindow, Norbert; Baum, Daniel; Prohaska, Steffen; Hege, Hans-Christian (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Molecular surfaces play an important role in studying the interactions between molecules. Visualizing the dynamic behavior of molecules is particularly interesting to gain insights into a molecular system. Only recently ...
    • Visualization and Analysis-Oriented Reconstruction of Material Interfaces 

      Meredith, Jeremy; Childs, Hank (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Reconstructing boundaries along material interfaces from volume fractions is a difficult problem, especially because the under-resolved nature of the input data allows for many correct interpretations. Worse, algorithms ...
    • The Readability of Path-Preserving Clusterings of Graphs 

      Archambault, Daniel; Purchase, Helen C.; Pinaud, Bruno (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Graph visualization systems often exploit opaque metanodes to reduce visual clutter and improve the readability of large graphs. This filtering can be done in a path-preserving way based on attribute values associated with ...
    • Non-iterative Second-order Approximation of Signed Distance Functions for Any Isosurface Representation 

      Molchanov, Vladimir; Rosenthal, Paul; Linsen, Lars (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Signed distance functions (SDF) to explicit or implicit surface representations are intensively used in various computer graphics and visualization algorithms. Among others, they are applied to optimize collision detection, ...
