      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2009)

    • Accelerating Volume Raycasting using Proxy Spheres 

      Liu, Baoquan; Clapworthy, Gordon J.; Dong, Feng (The Eurographics Association and Blackwell Publishing Ltd., 2009)
      In this paper, we propose an efficient solution that addresses the performance problems of current single-pass GPU raycasting algorithms. Our paper provides more control over the rendering process by introducing tighter ...

    • Adaptive Caustic Maps Using Deferred Shading 

      Wyman, Chris; Nichols, Greg (The Eurographics Association and Blackwell Publishing Ltd, 2009)

    • Adaptive Interleaved Sampling for Interactive High-Fidelity Rendering 

      Dubla, P.; Debattista, K.; Chalmers, A. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Recent advances have made interactive ray tracing (IRT) possible on consumer desktop machines. These advances have brought about the potential for interactive global illumination (IGI) with enhanced realism through physically ...

    • Affective Modelling: Profiling Geometrical Models with Human Emotional Responses 

      Lo, Cheng-Hung; Chu, Chih-Hsing (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper, a novel concept, Affective Modelling, is introduced to encapsulate the idea of creating 3D models based on the emotional responses that they may invoke. Research on perceptually-related issues in Computer ...

    • An Analytical Solution to Single Scattering in Homogeneous Participating Media 

      Pegoraro, Vincent; Parker, Steven G. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Despite their numerous applications, efficiently rendering participating media remains a challenging task due to the intricacy of the radiative transport equation. As they provide a generic means of solving a wide variety ...

    • Animating Pictures of Fluid using Video Examples 

      Okabe, Makoto; Anjyo, Ken; Igarashi, Takeo; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We propose a system that allows the user to design a continuous flow animation starting from a still fluid image. The basic idea is to apply the fluid motion extracted from a video example to the target image. The system ...

    • Animating Quadrupeds: Methods and Applications 

      Skrba, Ljiljana; Reveret, Lionel; Hetroy, Franck; Cani, Marie-Paule; O'Sullivan, Carol (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Films like Shrek, Madagascar, The Chronicles of Narnia and Charlotte s web all have something in common: realistic quadruped animations. While the animation of animals has been popular for a long time, the technical ...

    • Anisotropic Radiance-Cache Splatting for Efficiently Computing High-Quality Global Illumination with Lightcuts 

      Herzog, Robert; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Computing global illumination in complex scenes is even with todays computational power a demanding task. In this work we propose a novel irradiance caching scheme that combines the advantages of two state-of-the-art ...

    • 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 ...

    • Approximate on-Surface Distance Computation using Quasi-Developable Charts 

      Torchelsen, Rafael P.; Pinto, Francisco; Bastos, Rui; Comba, Joao L. D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      There is a vast number of applications that require distance field computation over triangular meshes. State-of-the-art algorithms have quadratic or sub-quadratic worst-case complexity, making them impractical for interactive ...

    • Approximating Gradients for Meshes and Point Clouds via Diffusion Metric 

      Luo, Chuanjiang; Safa, Issam; Wang, Yusu (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      The gradient of a function defined on a manifold is perhaps one of the most important differential objects in data analysis. Most often in practice, the input function is available only at discrete points sampled from the ...

    • Arches: a Framework for Modeling Complex Terrains 

      Peytavie, A.; Galin, E.; Grosjean, J.; Merillou, S. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper, we present a framework for representing complex terrains with such features as overhangs, arches and caves and including different materials such as sand and rocks. Our hybrid model combines a volumetric ...

    • Automatic Correction of Saturated Regions in Photographs using Cross-Channel Correlation 

      Masood, Syed Z.; Zhu, Jiejie; Tappen, Marshall F. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Incorrectly setting the camera s exposure can have a significant negative effect on a photograph. Over-exposing photographs causes pixels to exhibit unpleasant artifacts due to saturation of the sensor. Saturation removal ...

    • Autostereoscopic Rendering of Multiple Light Fields 

      Escriva, M.; Blasco, J.; Abad, F.; Camahort, E.; Vivo, R. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Light fields were introduced a decade ago as a new high-dimensional graphics rendering model. However, they have not been thoroughly used because their applications are very specific and their storage requirements are too ...

    • A Bayesian Monte Carlo Approach to Global Illumination 

      Brouillat, Jonathan; Bouville, Christian; Loos, Brad; Hansen, Charles; Bouatouch, Kadi (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Most Monte Carlo rendering algorithms rely on importance sampling to reduce the variance of estimates. Importance sampling is efficient when the proposal sample distribution is well-suited to the form of the integrand but ...

    • Bidirectional Importance Sampling for Unstructured Direct Illumination 

      Wang, Rui; Akerlund, Oskar (The Eurographics Association and Blackwell Publishing Ltd, 2009)
