    • Locally Injective Mappings 

      Schüller, Christian; Kavan, Ladislav; Panozzo, Daniele; Sorkine-Hornung, Olga (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Mappings and deformations are ubiquitous in geometry processing, shape modeling, and animation. Numerous deformation energies have been proposed to tackle problems like mesh parameterization and volumetric deformations. ...

    • Noise-Adaptive Shape Reconstruction from Raw Point Sets 

      Giraudot, Simon; Cohen-Steiner, David; Alliez, Pierre (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose a noise-adaptive shape reconstruction method specialized to smooth, closed shapes. Our algorithm takes as input a defect-laden point set with variable noise and outliers, and comprises three main steps. First, ...

    • An Operator Approach to Tangent Vector Field Processing 

      Azencot, Omri; Ben-Chen, Mirela; Chazal, Frédéric; Ovsjanikov, Maks (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we introduce a novel coordinate-free method for manipulating and analyzing vector fields on discrete surfaces. Unlike the commonly used representations of a vector field as an assignment of vectors to the ...

    • PHOG: Photometric and Geometric Functions for Textured Shape Retrieval 

      Biasotti, Silvia; Cerri, Andrea; Giorgi, Daniela; Spagnuolo, Michaela (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper we target the problem of textured 3D object retrieval. As a first contribution, we show how to include photometric information in the persistence homology setting, also proposing a novel theoretical result ...

    • Practical Anisotropic Geodesy 

      Campen, Marcel; Heistermann, Martin; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The computation of intrinsic, geodesic distances and geodesic paths on surfaces is a fundamental low-level building block in countless Computer Graphics and Geometry Processing applications. This demand led to the development ...

    • Preface and Table of Contents 

      Yaron Lipman and Hao Zhang (The Eurographics Association and Blackwell Publishing Ltd., 2013)

    • Semantizing Complex 3D Scenes using Constrained Attribute Grammars 

      Boulch, Alexandre; Houllier, Simon; Marlet, Renaud; Tournaire, Olivier (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose a new approach to automatically semantize complex objects in a 3D scene. For this, we define an expressive formalism combining the power of both attribute grammars and constraint. It offers a practical conceptual ...

    • Shape Matching via Quotient Spaces 

      Ovsjanikov, Maks; Mérigot, Quentin; Patraucean, Viorica; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We introduce a novel method for non-rigid shape matching, designed to address the symmetric ambiguity problem present when matching shapes with intrinsic symmetries. Unlike the majority of existing methods which try to ...

    • Sparse Iterative Closest Point 

      Bouaziz, Sofien; Tagliasacchi, Andrea; Pauly, Mark (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Rigid registration of two geometric data sets is essential in many applications, including robot navigation, surface reconstruction, and shape matching. Most commonly, variants of the Iterative Closest Point (ICP) algorithm ...

    • 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 ...

    • Weak Convex Decomposition by Lines-of-sight 

      Asafi, Shmuel; Goren, Avi; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We define the convexity rank of a set of points to be the portion of mutually visible pairs of points out of the total number of pairs. Based on this definition of weak convexity, we introduce a spectral method that ...
