    • Priority Streamlines: A context-based Visualization of Flow Fields 

      Schlemmer, Michael; Hotz, Ingrid; Hamann, Bernd; Morr, Florian; Hagen, Hans (The Eurographics Association, 2007)
      Flow vector fields contain a wealth of information that needs to be visualized. As an extension of the well-known streamline technique, we have developed a context-based method for visualizing steady flow vector fields in ...

    • Animation of Orthogonal Texture-Based Vector Field Visualization 

      Bachthaler, Sven; Weiskopf, Daniel (The Eurographics Association, 2007)
      This paper introduces orthogonal vector field visualization on 2D manifolds: a representation by lines that are perpendicular to the input vector field. Line patterns are generated by line integral convolution (LIC). This ...

    • Visualization Methods for Vortex Rings and Vortex Breakdown Bubbles 

      Peikert, Ronald; Sadlo, Filip (The Eurographics Association, 2007)
      Vortex breakdown bubbles are a subject which is of interest in many disciplines such as aeronautics, mixing, and combustion. Existing visualization methods are based on stream surfaces, direct volume rendering, tensor field ...

    • Parametric Visualization of High Resolution Correlated Multi-spectral Features Using PCA 

      Broersen, Alexander; Liere, Robert van; Heeren, Ron M. A. (The Eurographics Association, 2007)
