    • Level of Detail Flow Simulation 

      Klar, Gergely (The Eurographics Association, 2008)
      In this paper we present a framework to simulate visually plausible large scale flow of fluids or smoke. To maintain real-time speed, we define the simulation over a coarse grid which is refined with a more detailed grid ...
    • Microquad Soft Shadow Mapping Revisited 

      Schwarz, Michael; Stamminger, Marc (The Eurographics Association, 2008)
      Recently, real-time soft shadow research saw many important contributions from the class of soft shadow mapping algorithms, where approximate occluder geometry is reconstructed from a shadow map and backprojected onto the ...
    • Rendering Method for Flat Origami 

      Mitani, Jun (The Eurographics Association, 2008)
      In flat Origami (Origami which is folded flat), some cases exist that have a closed-loop in the overlap order of faces after they are folded. It is difficult to display this shape correctly on the screen when Origami is ...
    • Physically-Based Interactive Sand Simulation 

      Pla-Castells, Marta; García-Fernandez, Ignacio; Martinez-Dura, Rafael J. (The Eurographics Association, 2008)
      The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather ...
    • A Fragile Watermarking Scheme for Authentication of Semi-regular Meshes 

      Wang, Kai; Lavoue, Guillaume; Denis, Florence; Baskurt, Atilla (The Eurographics Association, 2008)
      This paper presents a fragile watermarking scheme for authentication of 3D semi-regular meshes. After one wavelet decomposition, the watermark is inserted by slightly modifying the norms and orientations of the obtained ...
    • Physically Based Modeling of Ice with Bubbles 

      Madrazo, Carlos; Okada, Minoru (The Eurographics Association, 2008)
      Bubbles are an important characteristic that determine the appearance of ice. In this paper the authors propose a strategy in order to construct geometric representations of ice that integrates bubbles in an ice cube and ...
    • Efficient Soft Tissue Modelling Using Charged Particle Control Points 

      Buckley, Oliver; John, Nigel W. (The Eurographics Association, 2008)
      As the performance levels of personal computers increases so does the desire for more realistic and immersive software and simulation. An area where this is particularly the case is that of medical training simulation, ...
    • Boolean Operations for Free-form Models Represented in Geometry Images 

      Fu, Yan; Zhou, Bingfeng (The Eurographics Association, 2008)
      We present a Boolean operation algorithm for free-form solid models represented in geometry images. By taking advantage of the regular data organization of geometry images, our algorithm can perform efficient surface ...
    • Adaptive Remeshing of Non-Manifold Surfaces 

      Zilske, Michael; Lamecker, Hans; Zachow, Stefan (The Eurographics Association, 2008)
      We present a unified approach for consistent remeshing of arbitrary non-manifold triangle meshes with additional user-defined feature lines, which together form a feature skeleton. Our method is based on local operations ...
    • Knitty: 3D Modeling of Knitted Animals with a Production Assistant Interface 

      Igarashi, Yuki; Igarashi, Takeo; Suzuki, Hiromasa (The Eurographics Association, 2008)
      Knitty is an interactive design system for creating knitted animals. The user designs a 3D surface model using a sketching interface. The system automatically generates a knitting pattern and then visualizes the shape of ...
    • Real-Time Volumetric Tests Using Layered Depth Images 

      Trapp, Matthias; Doellner, Juergen (The Eurographics Association, 2008)
      This paper presents a new approach for performing efficiently 3D point-in-volume tests for solid and arbitrary complex shapes. It classifies a 3D point as inside or outside of a solid specified by 3D polygonal geometry. ...
