    • Interactive, Multiresolution Image-Space Rendering for Dynamic Area Lighting 

      Nichols, Greg; Penmatsa, Rajeev; Wyman, Chris (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Area lights add tremendous realism, but rendering them interactively proves challenging. Integrating visibility is costly, even with current shadowing techniques, and existing methods frequently ignore illumination variations ...

    • SafeGI: Type Checking to Improve Correctness in Rendering System Implementation 

      Ou, Jiawei; Pellacini, Fabio (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Historically, rendering system development has been mainly focused on improving the numerical accuracy of the rendering algorithms and their runtime efficiency. In this paper, we propose a method to improve the correctness ...

    • An Optimizing Compiler for Automatic Shader Bounding 

      Clarberg, Petrik; Toth, Robert; Hasselgren, Jon; Akenine-Moeller, Tomas (The Eurographics Association and Blackwell Publishing Ltd, 2010)

    • Fragment-Parallel Composite and Filter 

      Patney, Anjul; Tzeng, Stanley; Owens, John D. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a strategy for parallelizing the composite and filter operations suitable for an order-independent rendering pipeline implemented on a modern graphics processor. Conventionally, this task is parallelized across ...

    • Fragment-Parallel Composite and Filter 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2010)

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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, ...

    • Interactive Global Photon Mapping 

      Fabianowski, B.; Dingliana, J. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
