    • 3D Surface Reconstruction Using a Generalized Distance Function 

      Poranne, R.; Gotsman, C.; Keren, D. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We define a generalized distance function on an unoriented 3D point set and describe how it may be used to reconstruct a surface approximating these points. This distance function is shown to be a Mahalanobis distance in ...

    • 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 ...

    • Accurate Simplification of Multi-Chart Textured Models 

      Coll, N.; Paradinas, T. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Scanning and acquisition methods produce highly detailed surface meshes that need multi-chart parameterizations to reduce stretching and distortion. From these complex shape surfaces, high-quality approximations are ...

    • Adaptive and Feature-Preserving Subdivision for High-Quality Tetrahedral Meshes 

      Burkhart, D.; Hamann, B.; Umlauf, G. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an adaptive subdivision scheme for unstructured tetrahedral meshes inspired by the -subdivision scheme for triangular meshes. Existing tetrahedral subdivision schemes do not support adaptive refinement and have ...

    • Adaptive Volumetric Shadow Maps 

      Salvi, Marco; Vidimce, Kiril; Lauritzen, Andrew; Lefohn, Aaron (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We introduce adaptive volumetric shadow maps (AVSM), a real-time shadow algorithm that supports high-quality shadowing from dynamic volumetric media such as hair and smoke. The key contribution of AVSM is the introduction ...

    • Adding Depth to Cartoons Using Sparse Depth (In)equalities 

      Sykora, D.; Sedlacek, D.; Jinchao, S.; Dingliana, J.; Collins, S. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a novel interactive approach for adding depth information into hand-drawn cartoon images and animations. In comparison to previous depth assignment techniques our solution requires minimal user effort ...

    • Afrigraph: The African Computer Graphics Association and its Activities 

      Gain, J.; Strasser, W.; Hardy, A.; Marais, P. (The Eurographics Association and Blackwell Publishing Ltd, 2010)

    • Alleviating the Modifiable Areal Unit Problem within Probe-Based Geospatial Analyses 

      Butkiewicz, Thomas; Meentemeyer, Ross K.; Shoemaker, Douglas A.; Chang, Remco; Wartell, Zachary; Ribarsky, William (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present a probe-based interface for the exploration of the results of a geospatial simulation of urban growth. Because our interface allows the user great freedom in how they choose to define regions-of-interest to ...

    • Application of Visual Analytics for Thermal State Management in Large Data Centres 

      Hao, M. C.; Sharma, R. K.; Keim, D. A.; Dayal, U.; Patel, C.; Vennelakanti, R. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Today s large data centres are the computational hubs of the next generation of IT services. With the advent of dynamic smart cooling and rack level sensing, the need for visual data exploration is growing. If administrators ...

    • Arbitrary Importance Functions for Metropolis Light Transport 

      Hoberock, Jared; Hart, John C. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a generalization of the scalar importance function employed by Metropolis Light Transport (MLT) and related Markov chain rendering algorithms. Although MLT is known for its user-designable mutation rules, we ...

    • Articulated Billboards for Video-based Rendering 

      Germann, Marcel; Hornung, Alexander; Keiser, Richard; Ziegler, Remo; Wuermlin, Stephan; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a novel representation and rendering method for free-viewpoint video of human characters based on multiple input video streams. The basic idea is to approximate the articulated 3D shape of the human body using ...

    • Automatic Animation for Time-Varying Data Visualization 

      Yu, Li; Lu, Aidong; Ribarsky, William; Chen, Wei (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a digital storytelling approach that generates automatic animations for time-varying data visualization. Our approach simulates the composition and transition of storytelling techniques and synthesizes ...

    • Automatic Transfer Function Specification for Visual Emphasis of Coronary Artery Plaque 

      Glasser, S.; Oeltze, S.; Hennemuth, A.; Kubisch, C.; Mahnken, A.; Wilhelmsen, S.; Preim, B. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Cardiovascular imaging with current multislice spiral computed tomography (MSCT) technology enables a non-invasive evaluation of the coronary arteries. Contrast-enhanced MSCT angiography with high spatial resolution allows ...

    • B-Mesh: A Modeling System for Base Meshes of 3D Articulated Shapes
