    • Shape-simplifying Image Abstraction 

      Kang, Henry; Lee, Seungyong (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a simple algorithm for producing stylistic abstraction of a photograph. Based on mean curvature flow in conjunction with shock filter, our method simplifies both shapes and colors simultaneously while ...
    • Knitting a 3D Model 

      Igarashi, Yuki; Igarashi, Takeo; Suzuki, Hiromasa (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model ...
    • Gradient-based Interpolation and Sampling for Real-time Rendering of Inhomogeneous, Single-scattering Media 

      Ren, Zhong; Zhou, Kun; Lin, Stephen; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a real-time rendering algorithm for inhomogeneous, single scattering media, where all-frequency shading effects such as glows, light shafts, and volumetric shadows can all be captured. The algorithm first computes ...
    • Real-Time Depth-of-Field Rendering Using Point Splatting on Per-Pixel Layers 

      Lee, Sungkil; Kim, Gerard Jounghyun; Choi, Seungmoon (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a real-time method for rendering a depth-of-field effect based on the per-pixel layered splatting where source pixels are scattered on one of the three layers of a destination pixel. In addition, the missing ...
    • Local Volume Preservation for Skinned Characters 

      Rohmer, Damien; Hahmann, Stefanie; Cani, Marie-Paule (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is ...
    • Smart Motion Synthesis 

      Oshita, Masaki (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Creating long motion sequences is a time-consuming task even when motion capture equipment or motion editing tools are used. In this paper, we propose a system for creating a long motion sequence by combining elementary ...
    • A Resolution Independent Approach for the Accurate Rendering of Grooved Surfaces 

      Bosch, C.; Pueyo, X.; Merillou, S.; Ghazanfarpour, D. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a method for the accurate rendering of path-based surface details such as grooves, scratches and similar features. The method is based on a continuous representation of the features in texture space, ...
    • Caustic Forecasting: Unbiased Estimation of Caustic Lighting for Global Illumination 

      Budge, B. C.; Anderson, J. C.; Joy, K. I. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an unbiased method for generating caustic lighting using importance sampled Path Tracing with Caustic Forecasting. Our technique is part of a straightforward rendering scheme which extends the Illumination by ...
    • A Prism-Free Method for Silhouette Rendering in Inverse Displacement Mapping 

      Chen, Ying-Chieh; Chang, Chun-Fa (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Silhouette is a key feature that distinguishes displacement mapping from normal mapping. However the silhouette rendering in the GPU implementation of displacement mapping (which is often called inversed displacement ...
    • Interpolatory and Mixed Loop Schemes 

      Shi, Zhuo; Lin, Shujin; Luo, Xiaonan; Wang, Renhong (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a new interpolatory Loop scheme and an unified and mixed interpolatory and approximation subdivision scheme for triangular meshes. The former which is C1 continuous as same as the modified Butterfly ...
    • Progressive Interpolation based on Catmull-Clark Subdivision Surfaces 

      Chen, Zhongxian; Luo, Xiaonan; Tan, Le; Ye, Binghong; Chen, Jiapeng (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We introduce a scheme for constructing a Catmull-Clark subdivision surface that interpolates the vertices of a quadrilateral mesh with arbitrary topology. The basic idea here is to progressively modify the vertices of an ...
    • Simulating Inextensible Cloth Using Impulses 

      Ye, Juntao (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Computer simulation of cloth is often plagued by springs being over-stretched. The evaluation of impulses to prevent over-stretching is explained step-by-step. Our impulse approach controls the length of springs by a ...
    • Interactive Glossy Reflections using GPU-based Ray Tracing with Adaptive LOD 

      Yu, Xuan; Wang, Rui; Yu, Jingyi (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an interactive GPU-based algorithm for accurately rendering high-quality, dynamic glossy reflection effects from both HDR environment maps and local scene objects. Our method uses hardware rasterization to produce ...
    • Interactive Global Illumination for Deformable Geometry in CUDA 

      Schmitz, Arne; Tavenrath, Markus; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive global illumination for fully deformable scenes with dynamic relighting is currently a very elusive goal in the area of realistic rendering. In this work we propose a system that is based on explicit visibility ...
    • Photon-driven Irradiance Cache 

      Brouillat, J.; Gautron, P.; Bouatouch, K. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We describe a global illumination method combining two well known techniques: photon mapping and irradiance caching. The photon mapping method has the advantage of being view independent but requires a costly additional ...
