    • 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 ...
    • 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 ...

      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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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, ...
    • 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. ...
    • 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, ...
    • Fragment-Parallel Composite and Filter 

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

      Nguyen, Chuong H.; Kyung, Min-Ho; Lee, Joo-Haeng; Nam, Seung-Woo (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We propose a novel rendering method which supports interactive BRDF editing as well as relighting on a 3D scene. For interactive BRDF editing, we linearize an analytic BRDF model with basis BRDFs obtained from a principal ...
    • A Closed-Form Solution to Single Scattering for General Phase Functions and Light Distributions 

      Pegoraro, Vincent; Schott, Mathias; Parker, Steven G. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Due to the intricate nature of the equation governing light transport in participating media, accurately and efficiently simulating radiative energy transfer remains very challenging in spite of its broad range of applications. ...
    • 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. ...
