    • 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 ...

    • 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, ...

    • 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. ...

    • Compressive estimation for signal integration in rendering 

      Sen, Pradeep; Darabi, Soheil (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In rendering applications, we are often faced with the problem of computing the integral of an unknown function. Typical approaches used to estimate these integrals are often based on Monte Carlo methods that slowly converge ...

    • A Dynamic Noise Primitive for Coherent Stylization 

      Benard, P.; Lagae, A.; Vangorp, P.; Lefebvre, S.; Drettakis, G.; Thollot, J. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new solution for temporal coherence in non-photorealistic rendering (NPR) of animations. Given the conflicting goals of preserving the 2D aspect of the style and the 3D scene motion, any such solution is a ...

    • 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 ...

    • Fragment-Parallel Composite and Filter 

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

    • Grammar-based Encoding of Facades 

      Haegler, Simon; Wonka, Peter; Arisona, Stefan Mueller; Van Gool, Luc; Mueller, Pascal (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. ...

    • 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, ...

    • 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 ...

    • Interactive Rendering of Non-Constant, Refractive Media Using the Ray Equations of Gradient-Index Optics 

      Cao, Chen; Ren, Zhong; Guo, Baining; Zhou, Kun (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Existing algorithms can efficiently render refractive objects of constant refractive index. For a medium with a continuously varying index of refraction, most algorithms use the ray equation of geometric optics to compute ...

    • 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 ...

    • 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, ...

    • A Layered Particle-Based Fluid Model for Real-Time Rendering of Water 

      Bagar, Florian; Scherzer, Daniel; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a physically based real-time water simulation and rendering method that brings volumetric foam to the real-time domain, significantly increasing the realism of dynamic fluids. We do this by combining a particle-based ...

    • 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 ...

    • A New Ward BRDF Model with Bounded Albedo 

      Geisler-Moroder, David; Duer, Arne (The Eurographics Association and Blackwell Publishing Ltd, 2010)
