    • 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. ...

    • Extraction Of Feature Lines On Surface Meshes Based On Discrete Morse Theory 

      Sahner, Jan; Weber, Britta; Prohaska, Steffen; Lamecker, Hans (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We present an approach for extracting extremal feature lines of scalar indicators on surface meshes, based on discrete Morse Theory. By computing initial Morse-Smale complexes of the scalar indicators of the mesh, we obtain ...

    • Generating Color Palettes using Intuitive Parameters 

      Wijffelaars, Martijn; Vliegen, Roel; Wijk, Jarke J. van; Linden, Erik-Jan van der (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Color is widely used in data visualization to show data values. The proper selection of colors is critical to convey information correctly. In this paper, we present a technique for generating univariate lightness ordered ...

    • Physically-based Dye Advection for Flow Visualization 

      Li, Guo-Shi; Tricoche, Xavier; Hansen, Charles (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Dye advection is widely used in experimental flow analysis but has seen less use for visualization in computational fluid dynamics. One possible reason for this disconnect is the inaccuracy of the texture-based approach, ...

    • Particle Level Set Advection for the Interactive Visualization of Unsteady 3D Flow 

      Cuntz, Nicolas; Kolb, Andreas; Strzodka, Robert; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Typically, flow volumes are visualized by defining their boundary as iso-surface of a level set function. Grid-based level sets offer a good global representation but suffer from numerical diffusion of surface detail, ...
