    • Texture Design and Draping in 2D Images 

      Winnemoeller, H.; Orzan, A.; Boissieux, L.; Thollot, J. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a complete system for designing and manipulating regular or near-regular textures in 2D images. We place emphasis on supporting creative workflows that produce artwork from scratch. As such, our system provides ...
    • A Robust Illumination Estimate for Chromatic Adaptation in Rendered Images 

      Wilkie, Alexander; Weidlich, Andrea (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We propose a method that improves automatic colour correction operations for rendered images. In particular, we propose a robust technique for estimating the visible and pertinent illumination in a given scene. We do this ...
    • Locally Adapted Projections to Reduce Panorama Distortions 

      Kopf, Johannes; Lischinski, Dani; Deussen, Oliver; Cohen-Or, Daniel; Cohen, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Displaying panoramic and wide angle views on a flat 2D display surface is necessarily prone to distortions. Perspective projections are limited to fairly narrow view angles. Cylindrical and spherical projections can show ...
    • Anomalous Dispersion in Predictive Rendering 

      Weidlich, Andrea; Wilkie, Alexander (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In coloured media, the index of refraction does not decrease monotonically with increasing wavelength, but behaves in a quite non-monotonical way. This behaviour is called anomalous dispersion and results from the fact ...
    • Efficient and Accurate Rendering of Complex Light Sources 

      Kniep, S.; Haering, S.; Magnor, M. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a new method for estimating the radiance function of complex area light sources. The method is based on Jensen s photon mapping algorithm. In order to capture high angular frequencies in the radiance function, ...
    • Deterministic Importance Sampling with Error Diffusion 

      Szirmay-Kalos, Laszlo; Szecsi, Laszlo (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      This paper proposes a deterministic importance sampling algorithm that is based on the recognition that delta-sigma modulation is equivalent to importance sampling. We propose a generalization for delta-sigma modulation ...
    • Frontmatter 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    • ReduceM: Interactive and Memory Efficient Ray Tracing of Large Models 

      Lauterbach, Christian; Yoon, Sung-eui; Tang, Ming; Manocha, Dinesh (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel representation and algorithm, ReduceM, for memory efficient ray tracing of large scenes. ReduceM exploits the connectivity between triangles in a mesh and decomposes the model into triangle strips. We ...
    • Accelerating Ray Tracing using Constrained Tetrahedralizations 

      Lagae, Ares; Dutre, Philip (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we introduce the constrained tetrahedralization as a new acceleration structure for ray tracing. A constrained tetrahedralization of a scene is a tetrahedralization that respects the faces of the scene geometry. ...
    • Free Form Incident Light Fields 

      Unger, J.; Gustavson, S.; Larsson, P.; Ynnerman, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents methods for photo-realistic rendering using strongly spatially variant illumination captured from real scenes. The illumination is captured along arbitrary paths in space using a high dynamic range, ...
    • Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps 

      Sintorn, Erik; Eisemann, Elmar; Assarsson, Ulf (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that typically requires only a single render pass ...
    • Fast Soft Self-Shadowing on Dynamic Height Fields 

      Snydre, John; Nowrouzezahrai, Derek (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new, real-time method for rendering soft shadows from large light sources or lighting environments on dynamic height fields. The method first computes a horizon map for a set of azimuthal directions. To reduce ...
    • Enhancement of Bright Video Features for HDR Displays 

      Didyk, P.; Mantiuk, R.; Hein, M.; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      To utilize the full potential of new high dynamic range (HDR) displays, a system for the enhancement of bright luminous objects in video sequences is proposed. The system classifies clipped (saturated) regions as lights, ...
    • ScribbleBoost: Adding Classification to Edge-Aware Interpolation of Local Image and Video Adjustments 

      Li, Y.; Adelson, E.; Agarwala, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      One of the most common tasks in image and video editing is the local adjustment of various properties (e.g., saturation or brightness) of regions within an image or video. Edge-aware interpolation of user-drawn scribbles ...
    • Combining Confocal Imaging and Descattering 

      Fuchs, Christian; Heinz, Michael; Levoy, Marc; Seidel, Hans-Peter; Lensch, Hendrik P. A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In translucent objects, light paths are affected by multiple scattering, which is polluting any observation. Confocal imaging reduces the influence of such global illumination effects by carefully focusing illumination and ...
    • Compact, Fast and Robust Grids for Ray Tracing 

      Lagae, Ares; Dutre, Philip (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The focus of research in acceleration structures for ray tracing recently shifted from render time to time to image, the sum of build time and render time, and also the memory footprint of acceleration structures now ...
    • Shallow Bounding Volume Hierarchies for Fast SIMD Ray Tracing of Incoherent Rays 

      Dammertz, H.; Hanika, J.; Keller, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
