    • 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). ...

    • Fast Random Sampling of Triangular Meshes 

      Sik, Martin; Krivanek, Jaroslav (The Eurographics Association, 2013)
      We present a simple and fast algorithm for generating randomly distributed points on a triangle mesh with probability density specified by a two-dimensional texture. Efficiency is achieved by resampling the density texture ...

    • An Improved Friction Model for Cloth Simulation 

      Wong, Tszho H.; Leach, Geoff; Zambetta, Fabio (The Eurographics Association, 2013)
      Friction is a complex phenomenon that resists tangential motion between two contacting objects. In computer graphics, existing cloth simulation methods have typically used a Coulomb model for friction, both static and ...

    • Intelligent Interactive Volume Classification 

      Grau, Sergi; Puig, Anna; Escalera, Sergio; Salamó, Maria (The Eurographics Association, 2013)
      This paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ...

    • 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. ...
