    • GPU-Assisted High Quality Particle Rendering 

      Cha, Deukhyun; Son, Sungjin; Ihm, Insung (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Visualizing dynamic participating media in particle form by fully solving equations from the light transport theory is a computationally very expensive process. In this paper, we present a computational pipeline for particle ...

    • Hierarchical Image-Space Radiosity for Interactive Global Illumination 

      Nichols, Greg; Shopf, Jeremy; Wyman, Chris (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We introduce image-space radiosity and a hierarchical variant as a method for interactively approximating diffuse indirect illumination in fully dynamic scenes. As oft observed, diffuse indirect illumination contains mainly ...

    • Interactive Global Photon Mapping 

      Fabianowski, B.; Dingliana, J. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a photon mapping technique capable of computing high quality global illumination at interactive frame rates. By extending the concept of photon differentials to efficiently handle diffuse reflections, we generate ...

    • 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 ...

    • Motion based Painterly Rendering 

      Lee, H.; Lee, C. H.; Yoon, K. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Previous painterly rendering techniques normally use image gradients for deciding stroke orientations. Image gradients are good for expressing object shapes, but difficult to express the flow or movements of objects. In ...

    • Packet-based Hierarchal Soft Shadow Mapping 

      Yang, Baoguang; Feng, Jieqing; Guennebaud, Gael; Liu, Xinguo (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Recent soft shadow mapping techniques based on back-projection can render high quality soft shadows in real time. However, real time high quality rendering of large penumbrae is still challenging, especially when multilayer ...

    • 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 ...

    • Single Photo Estimation of Hair Appearance 

      Bonneel, Nicolas; Paris, Sylvain; Van De Panne, Michiel; Durand, Fredo; Drettakis, George (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Significant progress has been made in high-quality hair rendering, but it remains difficult to choose parameter values that reproduce a given real hair appearance. In particular, for applications such as games where naive ...

    • Soft Textured Shadow Volume 

      Forest, Vincent; Barthe, Loic; Guennebaud, Gael; Paulin, Mathias (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Efficiently computing robust soft shadows is a challenging and time consuming task. On the one hand, the quality of image-based shadows is inherently limited by the discrete property of their framework. On the other hand, ...

    • Spatial Directional Radiance Caching 

      Gassenbauer, Vaclav; Krivanek, Jaroslav; Bouatouch, Kadi (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a new approach for accelerated global illumination computation in scenes with glossy surfaces. Our algorithm combines sparse illumination computation used in the radiance caching algorithm with BRDF importance ...

    • 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 ...

    • The Use of Precomputed Triangle Clusters for Accelerated Ray Tracing in Dynamic Scenes 

      Garanzha, Kirill (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper we present a hybrid algorithm for building the bounding volume hierarchy (BVH) that is used in accelerating ray tracing of animated models. This algorithm precomputes densely packed clusters of triangles on ...
