    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, ...
  • Datasets and Benchmarks for Densely Sampled 4D Light Fields 

    Wanner, Sven; Meister, Stephan; Goldluecke, Bastian (The Eurographics Association, 2013)
    We present a new benchmark database to compare and evaluate existing and upcoming algorithms which are tailored to light field processing. The data is characterised by a dense sampling of the light fields, which best fits ...
  • 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 ...
  • 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 ...
  • Fine-Scale Editing of Continuous Volumes using Adaptive Surfaces 

    Ruhl, Kai; Wenger, Stephan; Franke, Dennis; Saretzki, Julius; Magnor, Marcus (The Eurographics Association, 2013)
    Many fields of science such as astronomy and astrophysics require the visualization and editing of smooth, continuous volume data. However, current high-level approaches to volume editing concentrate on segmentable volume ...
  • 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; ...
  • Interactive Direct Volume Rendering with Many-light Methods and Transmittance Caching 

    Weber, Christoph; Kaplanyan, Anton S.; Stamminger, Marc; Dachsbacher, Carsten (The Eurographics Association, 2013)
    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 ...
  • Illustrative Rendering of Particle Systems 

    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 ...
  • 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 ...
  • Geometric Point Light Source Calibration 

    Ackermann, Jens; Fuhrmann, Simon; Goesele, Michael (The Eurographics Association, 2013)
    We present a light position calibration technique based on a general arrangement of at least two reflective spheres in a single image. Contrary to other techniques we do not directly intersect rays for triangulation but ...
  • Closed-Form Hierarchical Finite Element Models for Part-Based Object Detection 

    Rak, Marko; Engel, Karin; Tönnies, Klaus D. (The Eurographics Association, 2013)
    In this work we address part-based object detection under variability of part shapes and spatial relations. Our approach bases on the hierarchical finite element modeling concept of Engel and Tönnies [ET09a, ET09b]. They ...
  • 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 ...
  • Epipolar Plane Image Refocusing for Improved Depth Estimation and Occlusion Handling 

    Diebold, Maximilian; Goldluecke, Bastian (The Eurographics Association, 2013)
    In contrast to traditional imaging, the higher dimensionality of a light field offers directional information about the captured intensity. This information can be leveraged to estimate the disparity of 3D points in the ...

    Haque, Md. Abedul; Marai, G. Elisabeta (The Eurographics Association, 2013)
