    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 ...
  • FastV: From-point Visibility Culling on Complex Models 

    Chandak, Anish; Antani, Lakulish; Taylor, Micah; Manocha, Dinesh (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We present an efficient technique to compute the potentially visible set (PVS) of triangles in a complex 3D scene from a viewpoint. The algorithm computes a conservative PVS at object space accuracy. Our approach traces a ...
  • Characteristic Point Maps 

    Wu, Hongzhi; Dorsey, Julie; Rushmeier, Holly (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Extremely dense spatial sampling is often needed to prevent aliasing when rendering objects with high frequency variations in geometry and reflectance. To accelerate the rendering process, we introduce characteristic point ...
  • Dart Throwing on Surfaces 

    Cline, D.; Jeschke, S.; White, K.; Razdan, A.; Wonka, P. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    In this paper we present dart throwing algorithms to generate maximal Poisson disk point sets directly on 3D surfaces. We optimize dart throwing by efficiently excluding areas of the domain that are already covered by ...
  • 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 ...
  • 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 ...
  • BTF Compression via Sparse Tensor Decomposition 

    Ruiters, Roland; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    In this paper, we present a novel compression technique for Bidirectional Texture Functions based on a sparse tensor decomposition. We apply the K-SVD algorithm along two different modes of a tensor to decompose it into a ...
  • 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 ...
  • 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 ...
  • Estimating Specular Roughness and Anisotropy from Second Order Spherical Gradient Illumination 

    Ghosh, Abhijeet; Chen, Tongbo; Peers, Pieter; Wilson, Cyrus A.; Debevec, Paul (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    This paper presents a novel method for estimating specular roughness and tangent vectors, per surface point, from polarized second order spherical gradient illumination patterns. We demonstrate that for isotropic BRDFs, ...
  • 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 ...
  • Fast Global Illumination on Dynamic Height Fields 

    Nowrouzezahrai, Derek; Snyder, John (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We present a real-time method for rendering global illumination effects from large area and environmental lights on dynamic height fields. In contrast to previous work, our method handles inter-reflections (indirect lighting) ...
  • 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 ...
  • 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, ...
  • 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 ...

    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, ...
  • 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 ...
