      Chandler, Jennifer; Obermaier, Harald; Joy, Kenneth I. (The Eurographics Association, 2013)
      Sets of particles are a frequently used tool for the exploration of time-varying flow fields due to their ease of use and conceptual simplicity. Understanding temporal changes in such particle systems can be difficult with ...
    • Image Based Rendering from Perspective and Orthographic Images for Autostereoscopic Multi-View Displays 

      Jung, Daniel; Koch, Reinhard (The Eurographics Association, 2013)
      Current autostereoscopic (AS) multi-view displays for video that are targeted at the market allow typically up to 60 frames per second and offer between 20 and 60 different views per pixel. Future full parallax AS displays ...
    • Integrated Multi-aspect Visualization of 3D Fluid Flows 

      Brambilla, Andrea; Andreassen, Øyvind; Hauser, Helwig (The Eurographics Association, 2013)
      The motion of a fluid is affected by several intertwined flow aspects. Analyzing one aspect at a time can only yield partial information about the flow behavior. More details can be revealed by studying their interactions. ...

      In this paper we present an interactive global illumination method for Direct Volume Rendering (DVR) based on the many-light approach, a class of global illumination methods which gained much interest recently. We extend ...
    • Level of Detail for Real-Time Volumetric Terrain Rendering 

      Scholz, Manuel; Bender, Jan; Dachsbacher, Carsten (The Eurographics Association, 2013)
      Terrain rendering is an important component of many GIS applications and simulators. Most methods rely on heightmap-based terrain which is simple to acquire and handle, but has limited capabilities for modeling features ...
    • Local Extraction of Bifurcation Lines 

      Machado, Gustavo M.; Sadlo, Filip; Ertl, Thomas (The Eurographics Association, 2013)
      We present local extraction of bifurcation lines together with extraction of their manifolds, a topological feature that has not yet been sufficiently recognized in scientific visualization. The bifurcation lines are ...
    • Mobile Image Retargeting 

      Graf, Daniel; Panozzo, Daniele; Sorkine-Hornung, Olga (The Eurographics Association, 2013)
      We propose an algorithm for axis-aligned content-aware image retargeting that is specifically optimized for mobile devices, and we show that interactive image retargeting is possible even with a low-power, mobile CPU. Our ...
    • A New Framework for Fitting Shape Models to Range Scans: Local Statistical Shape Priors Without Correspondences 

      Last, Carsten; Winkelbach, Simon; Wahl, Friedrich M. (The Eurographics Association, 2013)
      Statistical shape models provide an important means in many applications in computer vision and computer graphics. However, the major problems are that the majority of these shape models require dense pointcorrespondences ...
    • Non-Sampled Anti-Aliasing 

      Auzinger, Thomas; Musialski, Przemyslaw; Preiner, Reinhold; Wimmer, Michael (The Eurographics Association, 2013)
      In this paper we present a parallel method for high-quality edge anti-aliasing in rasterization. In contrast to traditional graphics hardware methods, which rely on massive oversampling to combat aliasing issues, we evaluate ...
    • Optimising Aperture Shapes for Depth Estimation 

      Sellent, Anita; Favaro, Paolo (The Eurographics Association, 2013)
      The finite depth of field of a real camera can be used to estimate the depth structure of a scene. While the distance of an object from the plane in focus determines the defocus blur size, the shape of the aperture determines ...
    • Parallelized Global Brain Tractography 

      Philips, Stefan; Hlawitschka, Mario; Scheuermann, Gerik (The Eurographics Association, 2013)
      Most brain tractography algorithms suffer from lower accuracy, because they use only information in a certain neighborhood and reconstruct the tracts independently. Global brain tractography algorithms compensate the lack ...
    • Progressive Visibility Caching for Fast Indirect Illumination 

      Ulbrich, Justus; Novák, Jan; Rehfeld, Hauke; Dachsbacher, Carsten (The Eurographics Association, 2013)
      Rendering realistic images requires exploring the vast space of all possible paths that light can take between emitters and receivers. Thanks to the advances in rendering we can tackle this problem using different algorithms; ...
    • Sampled and Analytic Rasterization 

      Auzinger, Thomas; Wimmer, Michael (The Eurographics Association, 2013)
      In this poster we present an overview of exact anti-aliasing (AA) methods in rasterization. In contrast to the common supersampling approaches for visibility AA (e.g. MSAA) or both visibility and shading AA (e.g. SSAA, ...
    • A Semi-Automated Method for Subject-Specific Modeling of the Spinal Canal from Computed Tomography Images and Dynamic Radiographs 

      Haque, Md. Abedul; Marai, G. Elisabeta (The Eurographics Association, 2013)
      Shrinkage of the spinal canal may be due to congenital or degenerative conditions, and it causes many spinerelated diseases. We present a semi-automated method to computationally reconstruct spinal canal models from static ...
    • Simulation of Time-of-Flight Sensors using Global Illumination 

      Meister, Stephan; Nair, Rahul; Kondermann, Daniel (The Eurographics Association, 2013)
      Time-of-Flight (ToF) cameras use specialized sensors and modulated infrared light to simultaneously obtain depth, amplitude and intensity images. Depth images from such cameras suffer from various errors which exhibit a ...
