      Rathke, Brad; Wald, Ingo; Chiu, Kenneth; Brownlee, Carson (The Eurographics Association, 2015)
      Efficient visualization of unstructured data is vital for domain scientists, yet is often impeded by techniques which rely on intermediate representations that consume time and memory, require resampling data, or inefficient ...
    • Visualization Showcase: General-Relativistic Black Hole Visualization 

      Müller, Thomas; Boblest, Sebastian; Weiskopf, Daniel (The Eurographics Association, 2015)
      Black holes are among the most fascinating and weird objects in the universe. They distort space and time in their close neighborhood in a way that is far beyond our every day experience. We demonstrate the visual effects ...

      We present a novel technique to visualize wave propagation in 2D scalar fields. Direct visualization of wave fronts is susceptible to visual clutter and interpretation difficulties due to space-time interference and global ...
    • Memory-Efficient On-The-Fly Voxelization of Particle Data
