    • Semi-Stochastic Tilings for Example-Based Texture Synthesis 

      Schloemer, Thomas; Deussen, Oliver (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We investigate semi-stochastic tilings based on Wang or corner tiles for the real-time synthesis of example-based textures. In particular, we propose two new tiling approaches: (1) to replace stochastic tilings with ...
    • Patch-based Texture Interpolation 

      Ruiters, Roland; Schnabel, Ruwen; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper, we present a novel exemplar-based technique for the interpolation between two textures that combines patch-based and statistical approaches. Motivated by the notion of texture as a largely local phenomenon, ...
    • Interactive Editing of Lighting and Materials using a Bivariate BRDF Representation 

      Sitthi-Amorn, Pitchaya; Romeiro, Fabiano; Zickler, Todd; Lawrence, Jason (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new Precomputed Radiance Transfer (PRT) algorithm based on a two dimensional representation of isotropic BRDFs. Our approach involves precomputing matrices that allow quickly mapping environment lighting, which ...
    • An Optimizing Compiler for Automatic Shader Bounding 

      Clarberg, Petrik; Toth, Robert; Hasselgren, Jon; Akenine-Moeller, Tomas (The Eurographics Association and Blackwell Publishing Ltd, 2010)
    • 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 ...
    • Multi-Image Based Photon Tracing for Interactive Global Illumination of Dynamic Scenes 

      Yao, Chunhui; Wang, Bin; Chan, Bin; Yong, Junhai; Paul, Jean-Claude (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Image space photon mapping has the advantage of simple implementation on GPU without pre-computation of complex acceleration structures. However, existing approaches use only a single image for tracing caustic photons, so ...
    • 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 ...
    • Fast Estimation and Rendering of Indirect Highlights 

      Laurijssen, J.; Wang, R.; Dutre, Ph.; Brown, B.J. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper proposes a method for efficiently rendering indirect highlights. Indirect highlights are caused by the primary light source reflecting off two or more glossy surfaces. Accurately simulating such highlights is ...
    • Adaptive Volumetric Shadow Maps 

      Salvi, Marco; Vidimce, Kiril; Lauritzen, Andrew; Lefohn, Aaron (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We introduce adaptive volumetric shadow maps (AVSM), a real-time shadow algorithm that supports high-quality shadowing from dynamic volumetric media such as hair and smoke. The key contribution of AVSM is the introduction ...
    • 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 ...
    • Real-Time Concurrent Linked List Construction on the GPU 

      Yang, Jason C.; Hensley, Justin; Gruen, Holger; Thibieroz, Nicolas (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We introduce a method to dynamically construct highly concurrent linked lists on modern graphics processors. Once constructed, these data structures can be used to implement a host of algorithms useful in creating complex ...
    • Visibility Editing For All-Frequency Shadow Design 

      Obert, Juraj; Pellacini, Fabio; Pattanaik, Sumanta (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an approach for editing shadows in all-frequency lighting environments. To support artistic control, we propose to decouple shadowing from lighting and focus on providing intuitive controls to edit the former. ...
    • BendyLights: Artistic Control of Direct Illumination by Curving Light Rays 

      Kerr, William B.; Pellacini, Fabio; Denning, Jonathan D. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In computer cinematography, artists routinely use non-physical lighting models to achieve desired appearances. This paper presents BendyLights, a non-physical lighting model where light travels nonlinearly along splines, ...
    • Fragment-Parallel Composite and Filter 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2010)
    • Sparsely Precomputing The Light Transport Matrix for Real-Time Rendering 

      Huang, Fu-Chung; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Precomputation-based methods have enabled real-time rendering with natural illumination, all-frequency shadows, and global illumination. However, a major bottleneck is the precomputation time, that can take hours to days. ...
    • Two Methods for Fast Ray-Cast Ambient Occlusion 

      Laine, Samuli; Karras, Tero (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Ambient occlusion has proven to be a useful tool for producing realistic images, both in offline rendering and interactive applications. In production rendering, ambient occlusion is typically computed by casting a large ...
    • Spectralization: Reconstructing spectra from sparse data 

      Rump, Martin; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Traditional RGB reflectance and light data suffers from the problem of metamerism and is not suitable for rendering purposes where exact color reproduction under many different lighting conditions is needed. Nowadays many ...
    • An Image-Based Approach for Stochastic Volumetric and Procedural Details 

      Gilet, G.; Dischler, J-M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Noisy volumetric details like clouds, grounds, plaster, bark, roughcast, etc. are frequently encountered in nature and bring an important contribution to the realism of outdoor scenes. We introduce a new interactive approach, ...
    • Invisible Seams 

      Ray, Nicolas; Nivoliers, Vincent; Lefebvre, Sylvain; Levy, Bruno (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Surface materials are commonly described by attributes stored in textures (for instance, color, normal, or displacement). Interpolation during texture lookup provides a continuous value field everywhere on the surface, ...
    • On Floating-Point Normal Vectors 

      Meyer, Quirin; Suessmuth, Jochen; Sussner, Gerd; Stamminger, Marc; Greiner, Guenther (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper we analyze normal vector representations. We derive the error of the most widely used representation, namely 3D floating-point normal vectors. Based on this analysis, we show that, in theory, the discretization ...
