    • Bezier Crust on Quad Subdivision Surface 

      Wang, Jianzhong; Cheng, Fuhua (The Eurographics Association, 2013)
      Subdivision surfaces have been widely used in computer graphics and can be classified into two categories, approximating and interpolatory. Representative approximating schemes are Catmull-Clark (quad) and Loop (triangular). ...
    • 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 ...
    • Incomplete 3D Shape Retrieval via Sparse Dictionary Learning 

      Wan, Lili; Jiang, Jingyu; Zhang, Hao (The Eurographics Association, 2015)
      How to deal with missing data is one of the recurring questions in data analysis. The handling of significant missing data is a challenge. In this paper, we are interested in the problem of 3D shape retrieval where the ...
    • Non-rigid 3D Shape Retrieval via Sparse Representation 

      Wan, Lili; Li, Shuai; Miao, Zhenjiang J.; Cen, Yigang G. (The Eurographics Association, 2013)
      Shape descriptor design is an important but challenging problem for non-rigid 3D shape retrieval. Recently, bagof- words based methods are widely used to integrate a model's local shape descriptors into a global histogram. ...
    • Projecting Points onto Planar Parametric Curves by Local Biarc Approximation 

      Song, Hai-Chuan; Shi, Kan-Le; Yong, Jun-Hai; Zhang, Sen (The Eurographics Association, 2014)
      This paper proposes a geometric iteration algorithm for computing point projection and inversion on surfaces based on local biarc approximation. The iteration begins with initial estimation of the projection of the prescribed ...
