    • A Hierarchical Grid Based Framework for Fast Collision Detection 

      Fan, Wenshan; Wang, Bin; Paul, Jean-Claude; Sun, Jiaguang (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a novel hierarchical grid based method for fast collision detection (CD) for deformable models on GPU architecture. A two-level grid is employed to accommodate the non-uniform distribution of practical scene ...

    • A Multiscale Approach to Optimal Transport 

      Mérigot, Quentin (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper, we propose an improvement of an algorithm of Aurenhammer, Hoffmann and Aronov to find a least square matching between a probability density and finite set of sites with mass constraints, in the Euclidean ...

    • On the Shape of a Set of Points and Lines in the Plane 

      Kreveld, Marc van; Lankveld, Thijs van; Veltkamp, Remco C. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Detailed geometric models of the real world are in increasing demand. LiDAR data is appropriate to reconstruct urban models. In urban scenes, the individual surfaces can be reconstructed and connected to form the scene ...

    • Stable Morse Decompositions for Piecewise Constant Vector Fields on Surfaces 

      Szymczak, Andrzej (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Numerical simulations and experimental observations are inherently imprecise. Therefore, most vector fields of interest in scientific visualization are known only up to an error. In such cases, some topological features, ...
