    • Geometry-driven Visualization of Microscopic Structures in Biology 

      Mosaliganti, Kishore; Machiraju, Raghu; Huang, Kun; Leone, Gustavo (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      At a microscopic resolution, biological structures are composed of cells, red blood corpuscles (RBCs), cytoplasm and other microstructural components. There is a natural pattern in terms of distribution, arrangement and ...

    • Exploratory Visualization of Animal Kinematics Using Instantaneous Helical Axes

      We present novel visual and interactive techniques for exploratory visualization of animal kinematics using instantaneous helical axes (IHAs). The helical axis has been used in orthopedics, biomechanics, and structural ...

    • Illustrative Hybrid Visualization and Exploration of Anatomical and Functional Brain Data 

      Jainek, Werner M.; Born, Silvia; Bartz, Dirk; Straßer, Wolfgang; Fischer, Jan (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Common practice in brain research and brain surgery involves the multi-modal acquisition of brain anatomy and brain activation data. These highly complex three-dimensional data have to be displayed simultaneously in order ...

    • Interaction-Dependent Semantics for Illustrative Volume Rendering 

      Rautek, Peter; Bruckner, Stefan; Gröller, M. Eduard (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      In traditional illustration the choice of appropriate styles and rendering techniques is guided by the intention of the artist. For illustrative volume visualizations it is difficult to specify the mapping between the 3D ...

    • Raycasting of Light Field Galleries from Volumetric Data 

      Rezk-Salama, Christof; Todt, Severin; Kolb, Andreas (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The paper describes a technique to generate high-quality light field representations from volumetric data. We show how light field galleries can be created to give unexperienced audiences access to interactive high-quality ...

    • TimeRadarTrees: Visualizing Dynamic Compound Digraphs 

      Burch, Michael; Diehl, Stephan (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The evolution of dependencies in information hierarchies can be modeled by sequences of compound digraphs with edge weights. In this paper we present a novel approach to visualize such sequences of graphs. It uses radial ...

    • Interactive Visualization for Memory Reference Traces 

      Choudhury, A. N. M. Imroz; Potter, Kristin C.; Parker, Steven G. (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We present the Memory Trace Visualizer (MTV), a tool that provides interactive visualization and analysis of the sequence of memory operations performed by a program as it runs. As improvements in processor performance ...

    • Code Flows: Visualizing Structural Evolution of Source Code 

      Telea, Alexandru; Auber, David (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Understanding detailed changes done to source code is of great importance in software maintenance. We present Code Flows, a method to visualize the evolution of source code geared to the understanding of fine and mid-level ...

    • GPU Local Triangulation: an Interpolating Surface Reconstruction Algorithm 

      Buchart, Carlos; Borro, Diego; Amundarain, Aiert (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      A GPU capable method for surface reconstruction from unorganized point clouds without additional information, called GLT (GPU Local Triangulation), is presented. The main objective of this research is the generation of a ...

    • Computing Local Signed Distance Fields for Large Polygonal Models 

      Chang, Byungjoon; Cha, Deukhyun; Ihm, Insung (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The signed distance field for a polygonal model is a useful representation that facilitates efficient computation in many visualization and geometric processing tasks. Often it is more effective to build a local distance ...

    • Quality Isosurface Mesh Generation Using an Extended Marching Cubes Lookup Table 

      Raman, Sundaresan; Wenger, Rephael (The Eurographics Association and Blackwell Publishing Ltd., 2008)

    • Concurrent Viewing of Multiple Attribute-Specific Subspaces 

      Sisneros, Robert; Johnson, C. Ryan; Huang, Jian (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      In this work we present a point classification algorithm for multi-variate data. Our method is based on the concept of attribute subspaces, which are derived from a set of user specified attribute target values. Our ...

    • A Four-level Focus + Context Approach to Interactive Visual Analysis of Temporal Features in Large Scientific Data 

      Muigg, Philipp; Kehrer, Johannes; Oeltze, Steffen; Piringer, Harald; Doleisch, Helmut; Preim, Bernhard; Hauser, Helwig (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      In this paper we present a new approach to the interactive visual analysis of time-dependent scientific data - both from measurements as well as from computational simulation - by visualizing a scalar function over time ...

    • Visual Comparison of Hierarchically Organized Data 

      Holten, Danny; Wijk, Jarke J. van (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We provide a novel visualization method for the comparison of hierarchically organized data. Our technique visualizes a pair of hierarchies that are to be compared and simultaneously depicts how these hierarchies are related ...

    • Automatic Detection and Visualization of Distinctive Structures in 3D Unsteady Multi-fields 

      Jänicke, Heike; Böttinger, Michael; Tricoche, Xavier; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Current unsteady multi-field simulation data-sets consist of millions of data-points. To efficiently reduce this enormous amount of information, local statistical complexity was recently introduced as a method that identifies ...

    • Animating Causal Overlays 

      Bartram, Lyn; Yao, Miao (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Most approaches to representing causality, such as the common causal graph, require a separate and static view, but in many cases it is useful to add the dimension of causality to the context of an existing visualization. ...
