      Chuang, Johnson; Weiskopf, Daniel; Moeller, Torsten (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a design technique for colors with the purpose of lowering the energy consumption of the display device. Our approach is based on a screen space variant energy model. The result of our design is a set of ...
    • Example-Based Rendering of Eye Movements 

      Banf, Michael and Blanz, Volker (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      This paper describes a model for example-based, photo-realistic rendering of eye movements in 3D facial animation. Based on 3D scans of a face with different gaze directions, the model captures the motion of the eyeball ...
    • Fast BVH Construction on GPUs 

      Lauterbach, C.; Garland, M.; Sengupta, S.; Luebke, D.; Manocha, D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present two novel parallel algorithms for rapidly constructing bounding volume hierarchies on manycore GPUs. The first uses a linear ordering derived from spatial Morton codes to build hierarchies extremely quickly and ...
    • Fast GPU-based Adaptive Tessellation with CUDA 

      Schwarz, Michael; Stamminger, Marc (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Compact surface descriptions like higher-order surfaces are popular representations for both modeling and animation. However, for fast graphics-hardware-assisted rendering, they usually need to be converted to triangle ...
    • Feature Preserving Point Set Surfaces based on Non-Linear Kernel Regression 

      Oeztireli, A. C.; Guennebaud, G.; Gross, M. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Moving least squares (MLS) is a very attractive tool to design effective meshless surface representations. However, as long as approximations are performed in a least square sense, the resulting definitions remain sensitive ...
    • Frontmatter 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    • Genuinity Signatures: Designing Signatures for Verifying 3D Object Genuinity 

      Aliaga, Daniel G.; Atallah, Mikhail J. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      3D computer graphics models and digitally-controlled manufacturing have come together to enable the design, visualization, simulation, and automated creation of complex 3D objects. In our work, we propose and implement a ...
    • Heightfield and spatially varying BRDF Reconstruction for Materials with Interreflections 

      Ruiters, Roland; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Photo-realistic reproduction of material appearance from images has widespread use in applications ranging from movies over advertising to virtual prototyping. A common approach to this task is to reconstruct the small ...
    • Hydraulic Erosion Using Smoothed Particle Hydrodynamics 

      Kristof, P.; Benes, B.; Kivanek, J.; St ava, O. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      This paper presents a new technique for modification of 3D terrains by hydraulic erosion. It efficiently couples fluid simulation using a Lagrangian approach, namely the Smoothed Particle Hydrodynamics (SPH) method, and a ...
    • Image Appearance Exploration by Model-Based Navigation 

      Shapira, L.; Shamir, A.; Cohen-Or, D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Changing the appearance of an image can be a complex and non-intuitive task. Many times the target image colors and look are only known vaguely and many trials are needed to reach the desired results. Moreover, the effect ...
    • Implicit Contact Handling for Deformable Objects 

      Otaduy, Miguel A.; Tamstorf, Rasmus; Steinemann, Denis; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present an algorithm for robust and efficient contact handling of deformable objects. By being aware of the internal dynamics of the colliding objects, our algorithm provides smooth rolling and sliding, stable stacking, ...
    • Importance Sampling Spherical Harmonics 

      Jarosz, Wojciech; Carr, Nathan A.; Jensen, Henrik Wann (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper we present the first practical method for importance sampling functions represented as spherical harmonics (SH). Given a spherical probability density function (PDF) represented as a vector of SH coefficients, ...
    • Interactive Geometric Simulation of 4D Cities 

      Weber, Basil; Mueller, Pascal; Wonka, Peter; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a simulation system that can simulate a three-dimensional urban model over time. The main novelty of our approach is that we do not rely on land-use simulation on a regular grid, but instead build a complete and ...
    • Into the Blue: Better Caustics through Photon Relaxation 

      Spencer, B.; Jones, M.W. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      The photon mapping method is one of the most popular algorithms employed in computer graphics today. However, obtaining good results is dependent on several variables including kernel shape and bandwidth, as well as the ...
    • LazyBrush: Flexible Painting Tool for Hand-drawn Cartoons 

      Sykora, Daniel; Dingliana, John; Collins, Steven (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper we present LazyBrush, a novel interactive tool for painting hand-made cartoon drawings and animations. Its key advantage is simplicity and flexibility. As opposed to previous custom tailored approaches [SBv05, ...
    • Learning good views through intelligent galleries 

      Vieira, Thales; Bordignon, Alex; Peixoto, Adelailson; Tavares, Geovan; Lopes, Helio; Velho, Luiz; Lewiner, Thomas (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      The definition of a good view of a 3D scene is highly subjective and strongly depends on both the scene content and the 3D application. Usually, camera placement is performed directly by the user, and that task may be ...
