      Liu, Xin; Rokne, Jon (The Eurographics Association, 2012)
      Bokeh is important for the realism and aesthetics of graphical rendering, but hard to simulate. In this paper, we propose a novel method that conceptually shoots a 3D display with a physical camera. While a high-quality ...
    • Ellipsoidal Cube Maps for Accurate Rendering of Planetary-Scale Terrain Data 

      Lambers, Martin; Kolb, Andreas (The Eurographics Association, 2012)
      Advances in sensor technology lead to a rapidly growing number of terrain data sets with very high spatial resolution. To allow reliable visual analysis of this data, terrain data for planetary objects needs to be rendered ...
    • Optimizing Geometry-aware Pants Decomposition 

      Zhang, Kang; Li, Xin (The Eurographics Association, 2012)
      We present a computational framework to optimize the pants decomposition of surfaces with non-trivial topology. A pants decomposition segments a surface into a set of sub-patches each of which is genus-0 with 3 boundaries. ...
    • Point-wise Adaptive Filtering for Fast Monte Carlo Noise Reduction 

      Guo, Jie; Pan, Jingui (The Eurographics Association, 2012)
      Monte Carlo based photorealistic image synthesis has proven to be one of the most flexible and powerful rendering techniques, but is plagued with undesirable artifacts known as Monte Carlo noise. We present an adaptive ...
    • User-Assisted Disparity Maps 

      Chen, Hsin-Yi; Lin, Yi-Shan; Shen, I-Chao; Luo, Sheng-Jie; Cheng, Wen-Huang; Chen, Bing-Yu (The Eurographics Association, 2012)
      In this paper, we present an intuitive and efficient system for correcting the artifacts and noises caused by imperfect disparity estimation. Disparity estimation is a very important and basic process for almost all ...
    • 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 ...
    • 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 ...
