    • 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 ...

    • 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. ...

    • 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. ...

    • 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 PCA Decomposition for Real-time BRDF Editing and Relighting with Global Illumination 

      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 ...

    • 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 ...

    • A New Ward BRDF Model with Bounded Albedo 

      Geisler-Moroder, David; Duer, Arne (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Due to its realistic appearance, computational convenience, and efficient Monte Carlo sampling, Ward s anisotropic BRDF is widely used in computer graphics for modeling specular reflection. Incorporating the criticism that ...

    • 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 ...

    • On the Effective Dimension of Light Transport 

      Lessig, Christian; Fiume, Eugene (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Light transport is often characterized within a high-dimensional space although practitioners have long known that it commonly behaves as a much lower-dimensional phenomenon. We study the effective dimension of light ...
