    • Parallel Blue-noise Sampling by Constrained Farthest Point Optimization 

      Chen, Renjie; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We describe a fast sampling algorithm for generating uniformly-distributed point patterns with good blue noise characteristics. The method, based on constrained farthest point optimization, is provably optimal and may be ...
    • Preface and Table of Contents 

      Eitan Grinspun and Niloy Mitra (The Eurographics Association and Blackwell Publishing Ltd., 2012)
    • Radial Symmetry Detection and Shape Characterization with the Multiscale Area Projection Transform 

      Giachetti, Andrea; Lovato, Christian (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a novel method to characterize 3D surfaces through the computation of a function called (multiscale) area projection transform, measuring the likelihood of points in the 3D space to be center of radial symmetry ...
    • Shape-Up: Shaping Discrete Geometry with Projections 

      Bouaziz, Sofien; Deuss, Mario; Schwartzburg, Yuliy; Weise, Thibaut; Pauly, Mark (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We introduce a unified optimization framework for geometry processing based on shape constraints. These constraints preserve or prescribe the shape of subsets of the points of a geometric data set, such as polygons, one-ring ...
    • Smooth Shape-Aware Functions with Controlled Extrema 

      Jacobson, Alec; Weinkauf, Tino; Sorkine, Olga (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Functions that optimize Laplacian-based energies have become popular in geometry processing, e.g. for shape deformation, smoothing, multiscale kernel construction and interpolation. Minimizers of Dirichlet energies, or ...
    • Soft Maps Between Surfaces 

      Solomon, Justin; Nguyen, Andy; Butscher, Adrian; Ben-Chen, Mirela; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      The problem of mapping between two non-isometric surfaces admits ambiguities on both local and global scales. For instance, symmetries can make it possible for multiple maps to be equally acceptable, and stretching, slippage, ...
    • Stream Surface Parametrization by Flow-Orthogonal Front Lines 

      Schulze, Maik; Germer, Tobias; Rössl, Christian; Theisel, Holger (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      The generation of discrete stream surfaces is an important and challenging task in scientific visualization, which can be considered a particular instance of geometric modeling. The quality of numerically integrated stream ...
    • Time-Discrete Geodesics in the Space of Shells 

      Heeren, Behrend; Rumpf, Martin; Wardetzky, Max; Wirth, Benedikt (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Building on concepts from continuum mechanics, we offer a computational model for geodesics in the space of thin shells, with a metric that reflects viscous dissipation required to physically deform a thin shell. Different ...
