    • Generating Smooth High-Quality Isosurfaces for Interactive Modeling and Visualization of Complex Terrains 

      Löffler, Falko; Schumann, Heidrun (The Eurographics Association, 2012)
      In modeling and rendering of complex procedural terrains the extraction of isosurfaces is an important part. In this paper we introduce an approach to generate high-quality isosurfaces from regular grids at interactive ...
    • Screen Space Spherical Harmonic Occlusion 

      Herholz, Sebastian; Schairer, Timo; Schilling, Andreas; Straßer, Wolfgang (The Eurographics Association, 2012)
      In this paper we present a new algorithm for real-time directional occlusion sampling. We combine the real-time capabilities of Screen Space Ambient Occlusion (SSAO) with the Spherical Harmonics (SH) representation of local ...
    • GPU-accelerated Interactive Material Aging 

      Günther, Tobias; Rohmer, Kai; Grosch, Thorsten (The Eurographics Association, 2012)
      A photorealistic appearance of a 3D scene is required in many applications today. Thereby, one vital aspect is the usage of realistic materials, for which a broad variety of reflectance models is available. When directly ...
    • Single-Pass Rendering of Day and Night Sky Phenomena 

      Müller, Daniel; Engel, Juri; Döllner, Jürgen (The Eurographics Association, 2012)
      This paper presents astronomical based rendering of skies as seen from low altitudes on earth, in respect to location, date, and time. The technique allows to compose an atmosphere with sun, multiple cloud layers, moon, ...
    • Hybrid Sample-based Surface Rendering 

      Reichl, Florian; Chajdas, Matthäus G.; Bürger, Kai; Westermann, Rüdiger (The Eurographics Association, 2012)
      The performance of rasterization-based rendering on current GPUs strongly depends on the abilities to avoid overdraw and to prevent rendering triangles smaller than the pixel size. Otherwise, the rates at which highresolution ...
    • Fast Accurate Soft Shadows with Adaptive Light Source Sampling 

      Schwärzler, Michael; Mattausch, Oliver; Scherzer, Daniel; Wimmer, Michael (The Eurographics Association, 2012)
      Physically accurate soft shadows in 3D applications can be simulated by taking multiple samples from all over the area light source and accumulating them. Due to the unpredictability of the size of the penumbra regions, ...
    • An Efficient Trim Structure for Rendering Large B-Rep Models 

      Claux, Frédéric; Vanderhaeghe, David; Barthe, Loïc; Paulin, Mathias; Jessel, Jean-Pierre; Croenne, David (The Eurographics Association, 2012)
      We present a multiresolution trim structure for fast and accurate B-Rep model visualization. To get a good tradeoff between performance and visual accuracy, we propose to use a vectorial but approximated representation of ...
    • Automatic Detection and Recognition of Engineered Nanoparticles in SEM Images 

      Kockentiedt, Stephen; Toennies, Klaus; Gierke, Erhardt; Dziurowitz, Nico; Thim, Carmen; Plitzko, Sabine (The Eurographics Association, 2012)
      Engineered nanoparticles have gained importance in recent years and will do so in the future, but their potential toxicity remains an open question. To better understand their effects on the human body, it is necessary to ...
    • Fast and Robust Landmark Tracking in X-ray Locomotion Sequences Containing Severe Occlusions 

      Amthor, Manuel; Haase, Daniel; Denzler, Joachim (The Eurographics Association, 2012)
      Recent advances in the understanding of animal locomotion have proven it to be a key element of many fields in biology, motion science, and robotics. For the analysis of walking animals, high-speed x-ray videography is ...
    • Interactive Geometry-Aware Segmentation for the Decomposition of Kaleidoscopic Images 

      Klehm, Oliver; Reshetouski, Ilya; Eisemann, Elmar; Seidel, Hans-Peter; Ihrke, Ivo (The Eurographics Association, 2012)
      Mirror systems have recently emerged as an alternative low-cost multi-view imaging solution. The use of these systems critically depends on the ability to compute the background of a multiply mirrored object. The images ...
    • Design and Fabrication of Faceted Mirror Arrays for Light Field Capture 

      Fuchs, Martin; Kächele, Markus; Rusinkiewicz, Szymon (The Eurographics Association, 2012)
      The high resolution of digital cameras has made single-shot, single-sensor acquisition of light fields feasible, though considerable design effort is still necessary in order to construct the necessary collection of optical ...
