    • Rendering Trees with Indirect Lighting in Real Time 

      Boulanger, K.; Bouatouch, K.; Pattanaik, S. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      High quality lighting is one of the challenges for interactive tree rendering. To this end, this paper presents a lighting model allowing real-time rendering of trees with convincing indirect lighting. Rather than defining ...

    • Geometry-Aware Framebuffer Level of Detail 

      Yang, Lei; Sander, Pedro V.; Lawrence, Jason (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper introduces a framebuffer level of detail algorithm for controlling the pixel workload in an interactive rendering application. Our basic strategy is to evaluate the shading in a low resolution buffer and, in a ...

    • Frame Sequential Interpolation for Discrete Level-of-Detail Rendering 

      Scherzer, Daniel; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a method for automatic interpolation between adjacent discrete levels of detail to achieve smooth LOD changes in image space. We achieve this by breaking the problem into two passes: We render the ...

    • Lazy Solid Texture Synthesis 

      Dong, Yue; Lefebvre, Sylvain; Tong, Xin; Drettakis, George (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Existing solid texture synthesis algorithms generate a full volume of color content from a set of 2D example images. We introduce a new algorithm with the unique ability to restrict synthesis to a subset of the voxels, ...

    • Ptex: Per-Face Texture Mapping for Production Rendering 

      Burley, Brent; Lacewell, Dylan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Explicit parameterization of subdivision surfaces for texture mapping adds significant cost and complexity to film production. Most parameterization methods currently in use require setup effort, and none are completely ...

    • Real-time Shading with Filtered Importance Sampling 

      Kivanek, Jaroslav; Colbert, Mark (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We propose an analysis of numerical integration based on sampling theory, whereby the integration error caused by aliasing is suppressed by pre-filtering. We derive a pre-filter for evaluating the illumination integral ...

    • An Analysis of the In-Out BRDF Factorization for View-Dependent Relighting 

      Mahajan, Dhruv; Tseng, Yu-Ting; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive rendering with dynamic natural lighting and changing view is a long-standing goal in computer graphics. Recently, precomputation-based methods for all-frequency relighting have made substantial progress in this ...

    • Exploiting Visibility Correlation in Direct Illumination 

      Clarberg, Petrik; Akenine-Moeller, Tomas (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The visibility function in direct illumination describes the binary visibility over a light source, e.g., an environment map. Intuitively, the visibility is often strongly correlated between nearby locations in time and ...

    • Table-driven Adaptive Importance Sampling 

      Cline, David; Adams, Daniel; Egbert, Parris (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Monte Carlo rendering algorithms generally rely on some form of importance sampling to evaluate the measurement equation. Most of these importance sampling methods only take local information into account, however, so the ...

    • Tensor Clustering for Rendering Many-Light Animations 

      Hasan, Milos; Velazquez-Armendariz, Edgar; Pellacini, Fabio; Bala, Kavita (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Rendering animations of scenes with deformable objects, camera motion, and complex illumination, including indirect lighting and arbitrary shading, is a long-standing challenge. Prior work has shown that complex lighting ...

    • Sequential Monte Carlo Adaptation in Low-Anisotropy Participating Media 

      Pegoraro, Vincent; Wald, Ingo; Parker, Steven G. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a novel method that effectively combines both control variates and importance sampling in a sequential Monte Carlo context. The radiance estimates computed during the rendering process are cached in a ...

    • Irradiance Gradients in the Presence of Participating Media and Occlusions 

      Jarosz, Wojciech; Zwicker, Matthias; Jensen, Henrik Wann (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a technique for computing translational gradients of indirect surface reflectance in scenes containing participating media and significant occlusions. These gradients describe how the incident ...

    • Precomputed Atmospheric Scattering 

      Bruneton, Eric; Neyret, Fabrice (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new and accurate method to render the atmosphere in real time from any viewpoint from ground level to outer space, while taking Rayleigh and Mie multiple scattering into account. Our method reproduces many ...

    • Preface, Table of Contents, Cover 

      Unknown author (The Eurographics Association and Blackwell Publishing, Inc, 2008)

    • Feature-Guided Dynamic Texture Synthesis on Continuous Flows 

      Narain, Rahul; Kwatra, Vivek; Lee, Huai-Ping; Kim, Theodore; Carlson, Mark; Lin, Ming C. (The Eurographics Association, 2007)
      We present a technique for synthesizing spatially and temporally varying textures on continuous flows using image or video input, guided by the physical characteristics of the fluid stream itself. This approach enables the ...

    • Interactive Smooth and Curved Shell Mapping 

      Jeschke, Stefan; Mantler, Stephan; Wimmer, Michael (The Eurographics Association, 2007)
      Shell mapping is a technique to represent three-dimensional surface details. This is achieved by extruding the triangles of an existing mesh along their normals, and mapping a 3D function (e.g., a 3D texture) into the ...

    • Compressed Random-Access Trees for Spatially Coherent Data 

      Lefebvre, Sylvain; Hoppe, Hugues (The Eurographics Association, 2007)
      Adaptive multiresolution hierarchies are highly efficient at representing spatially coherent graphics data. We introduce a framework for compressing such adaptive hierarchies using a compact randomly-accessible tree ...

    • Using Photographs to Enhance Videos of a Static Scene 

      Bhat, Pravin; Zitnick, C. Lawrence; Snavely, Noah; Agarwala, Aseem; Agrawala, Maneesh; Cohen, Michael; Curless, Brian; Kang, Sing Bing (The Eurographics Association, 2007)
      We present a framework for automatically enhancing videos of a static scene using a few photographs of the same scene. For example, our system can transfer photographic qualities such as high resolution, high dynamic range ...

    • High Dynamic Range Image Hallucination 

      Wang, Lvdi; Wei, Li-Yi; Zhou, Kun; Guo, Baining; Shum, Heung-Yeung (The Eurographics Association, 2007)
      We introduce high dynamic range image hallucination for adding high dynamic range details to the over-exposed and under-exposed regions of a low dynamic range image. Our method is based on a simple assumption: there exist ...
