    • Dynamic Time Warping Based 3D Contours 

      Croci, Simone; Smolic, Aljoscha; Wang, Oliver (The Eurographics Association, 2013)
      In this work, we present a method for computing 3D contours from the silhouettes of objects in multiple views. Our approach unwraps contours into 1D signals and computes an efficient, globally optimal alignment using a ...

    • 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 ...

    • Towards Multi-Kernel Ray Tracing for GPUs 

      Schiffer, Thomas; Fellner, Dieter W. (The Eurographics Association, 2013)
      Ray tracing is a widely used algorithm to compute images with high visual quality. Mapping ray tracing computations to massively parallel hardware architectures in an efficient manner is a difficult task. Based on an ...

    • 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, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
