    • Polygonal Surface Advection applied to Strange Attractors 

      Yan, S.; Max, N.; Ma, K.-L. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Strange attractors of 3D vector field flows sometimes have a fractal geometric structure in one dimension, and smooth surface behavior in the other two. General flow visualization methods show the flow dynamics well, but ...

    • Real-time Depth of Field Rendering via Dynamic Light Field Generation and Filtering 

      Yu, Xuan; Wang, Rui; Yu, Jingyi (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new algorithm for efficient rendering of high-quality depth-of-field (DoF) effects. We start with a single rasterized view (reference view) of the scene, and sample the light field by warping the reference ...

    • Semi-isometric Registration of Line Features for Flexible Fitting of Protein Structures 

      Abeysinghe, S.S.; Baker, M. L.; Chiu, W.; Ju, T. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper, we study a registration problem that is motivated by a practical biology problem - fitting protein structures to low-re solution density maps. We consider registration between two sets of lines features ...

    • A simple and robust thinning algorithm on cell complexes 

      Liu, L.; Chambers, E. W.; Letscher, D.; Ju, T. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Thinning is a commonly used approach for computing skeleton descriptors. Traditional thinning algorithms often have a simple, iterative structure, yet producing skeletons that are overly sensitive to boundary perturbations. ...

    • Towards Perceptual Simplification of Models with Arbitrary Materials 

      Menzel, Nicolas; Guthe, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Real-time rendering of models with high polygon count is still an important issue in interactive computer graphics. A common way to improve rendering performance is to generate different levels of detail of a model. These ...

    • Variance Soft Shadow Mapping 

      Yang, Baoguang; Dong, Zhao; Feng, Jieqing; Seidel, Hans-Peter; Kautz, Jan (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present variance soft shadow mapping (VSSM) for rendering plausible soft shadow in real-time. VSSM is based on the theoretical framework of percentage-closer soft shadows (PCSS) and exploits recent advances in variance ...

    • Video Painting via Motion Layer Manipulation 

      Huang, Hua; Zhang, Lei; Fu, Tian-Nan (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Temporal coherence is an important problem in Non-Photorealistic Rendering for videos. In this paper, we present a novel approach to enhance temporal coherence in video painting. Instead of painting on video frame, our ...
