    • Two Simple Single-pass GPU methods for Multi-channel Surface Voxelization of Dynamic Scenes 

      Gaitatzes, Athanasios; Mavridis, Pavlos; Papaioannou, Georgios (The Eurographics Association, 2011)
      An increasing number of rendering and geometry processing algorithms relies on volume data to calculate anything from effects like smoke/fluid simulations, visibility information or global illumination effects. We present ...

    • Visualizing Local Weather Characteristics Interpreted from Glider GPS Flight Logs 

      Hsieh, Tung-Ju; Kuester, Falko; Hutchinson, Tara (The Eurographics Association, 2011)
      Visualization can aid in improving the validation and evaluation of glider flight logs, which in turn can make the logs more meaningful in flight evaluation and planning. This paper presents techniques to interpret and ...

    • Perceptually-based Stroke Pattern Synthesis 

      Liu, Dongwei; Zhang, Junsong; Zhou, Changle (The Eurographics Association, 2011)

    • Real-time Realistic Voxel-based Rendering 

      Chang, S.-H.; Lai, Yu-Chi; Niu, Yuzhen; Liu, Feng; Hua, K.-L. (The Eurographics Association, 2011)
      With the advance of graphics hardware, setting 3D texture as render target is newly available to allow voxelization algorithms to record the existence, color and normal information in a voxel directly without specific ...

    • Feature-Aware Reconstruction of Volume Data via Trivariate Splines 

      Li, Bo; Qin, Hong (The Eurographics Association, 2011)
      In this paper, we propose a novel approach that transforms discrete volumetric data directly acquired from scanning devices into continuous spline representation with tensor-product regular structure. Our method is achieved ...

    • Sketch-based Breaking Waves 

      Zhang, Guijuan; Wen, Gaojin; Zhu, Dengming; Lu, Dianjie; Feng, Shengzhong (The Eurographics Association, 2011)
      We present a sketching method for animating breaking waves in this paper. Our approach allows an animator to control physically-based wave breaking effects by drawing the outline of the wave shape intuitively. To do this, ...

    • Real-time Rendering of Endless Cloud Animation 

      Iwasaki, Kei; Nishino, Takanori; Dobashi, Yoshinori (The Eurographics Association, 2011)
      In this paper, we propose a real-time animation method for dynamic clouds illuminated by sunlight and skylight with multiple scattering. In order to create animations of outdoor scenes, it is necessary to render time-varying ...

    • Feature Adaptive Surfel Set Simplification 

      Huang, Yan; Yan, Feihu; Wang, Bei; Peng, Jingliang (The Eurographics Association, 2011)
      In this paper we propose a novel scheme for simplifying a surfel set with the resultant surfels computed and distributed in an effort to preserve prominent geometric and textural features with a reduced number of primitives. ...

    • An Effective and Efficient Contour-based Corner Detector using Simple Triangular Theory 

      Sadat, R. M. Najmus; Teng, Shyh Wei; Lu, Guojun (The Eurographics Association, 2011)
      Corner detection is an important operation in many computer vision applications. Among the contour-based corner detectors in the literature, the Chord-to-Point Distance Accumulation (CPDA) detector is reported to have one ...

    • A Fast Simulation Method Using SPH and Wavelet for Sub-Particle-Scale Turbulent Flow 

      Fujisawa, Makoto; Mimura, Go; Amano, Toshiyuki; Miyazaki, Jun; Kato, Hirokazu (The Eurographics Association, 2011)
      This paper presents a fast simulation method for turbulent flow which uses a particle method and wavelet analysis. To simulate fluid flow, the method uses smoothed particle hydrodynamics (SPH), which discretizes the fluid ...

    • Fast Computing Adaptively Sampled Distance Field on GPU 

      Yin, Kangxue; Liu, Youquan; Wu, Enhua (The Eurographics Association, 2011)
      In this paper we present an efficient method to compute the signed distance field for a large triangle mesh, which can run interactively with GPU accelerated. Restricted by absence of flexible pointer addressing on GPU, ...

    • Feature-Aware Mesh for Image Retargeting 

      Niu, Yuzhen; Liu, Feng; Lai, Yu-chi (The Eurographics Association, 2011)
      Image retargeting adapts an input image to displays other than originally intended while minimizing visual distortion. Most warping-based methods formulate retargeting as a spatially-varying warping problem over a uniform ...

    • Diffusion Tensor Weighted Harmonic Fields for Feature Classification 

      Wang, Shengfa; Hou, Tingbo; Su, Zhixun; Qin, Hong (The Eurographics Association, 2011)
      This paper presents an efficient method for feature definition and classification on shapes. We tackle this challenge by exploring the weighted harmonic field (WHF), which is also the stable state of a heat diffusion ...
