      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. ...

      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)

    • 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 ...
