    • Discrete Line Congruences for Shading and Lighting 

      Wang, Jun; Jiang, Caigui; Bompas, Philippe; Wallner, Johannes; Pottmann, Hellmut (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Two-parameter families of straight lines (line congruences) are implicitly present in graphics and geometry processing in several important ways including lighting and shape analysis. In this paper we make them accessible ...

    • Fast and Robust Approximation of Smallest Enclosing Balls in Arbitrary Dimensions 

      Larsson, Thomas; Källberg, Linus (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, an algorithm is introduced that computes an arbitrarily fine approximation of the smallest enclosing ball of a point set in any dimension. This operation is important in, for example, classification, clustering, ...

    • Watertight Scenes from Urban LiDAR and Planar Surfaces 

      Kreveld, Marc van; Lankveld, Thijs van; Veltkamp, Remco C. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The demand for large geometric models is increasing, especially of urban environments. This has resulted in production of massive point cloud data from images or LiDAR. Visualization and further processing generally require ...
