    • Robust Image Denoising Using a Virtual Flash Image for Monte Carlo Ray Tracing 

      Moon, Bochang; Jun, Jong Yun; Lee, JongHyeob; Kim, Kunho; Hachisuka, Toshiya; Yoon, Sung-Eui (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose an efficient and robust image-space denoising method for noisy images generated by Monte Carlo ray tracing methods. Our method is based on two new concepts: virtual flash images and homogeneous pixels. Inspired ...

    • Scalable Symmetry Detection for Urban Scenes 

      Kerber, J.; Bokeloh, M.; Wand, M.; Seidel, H.-P. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we present a novel method for detecting partial symmetries in very large point clouds of 3D city scans. Unlike previous work, which has only been demonstrated on data sets of a few hundred megabytes maximum, ...

    • Simulation of Morphology Changes in Drying Leaves 

      Jeong, SoHyeon; Park, Si-Hyung; Kim, Chang-Hun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We introduce a biologically motivated simulation technique for the realistic shape deformation of drying leaves. In contrast to skeleton-based leaf deformation, our approach simulates the whole leaf surface to capture the ...

    • Synthetic Controllable Turbulence Using Robust Second Vorticity Confinement 

      He, S.; Lau, R. W. H. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Capturing fine details of turbulence on a coarse grid is one of the main tasks in real-time fluid simulation. Existing methods for doing this have various limitations. In this paper, we propose a new turbulence method that ...

    • Vega: Non-Linear FEM Deformable Object Simulator 

      Sin, F. S.; Schroeder, D.; Barbic, J. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This practice and experience paper describes a robust C++ implementation of several non-linear solid three-dimensional deformable object strategies commonly employed in computer graphics, named the Vega finite element ...

    • Visualization and Analysis of Second-Order Tensors: Moving Beyond the Symmetric Positive-Definite Case 

      Kratz, A.; Auer, C.; Stommel, M.; Hotz, I. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Tensors provide a powerful language to describe physical phenomena. Consequently, they have a long tradition in physics and appear in various application areas, either as the final result of simulations or as intermediate ...
