    • On Discrete Killing Vector Fields and Patterns on Surfaces 

      Mirela Ben-Chen; Adrian Butscher; Justin Solomon; Leonidas Guibas (2010)
      Symmetry is one of the most important properties of a shape, unifying form and function. It encodes semantic information on one hand, and affects the shape's aesthetic value on the other. Symmetry comes in many flavors, ...
    • One Point Isometric Matching with the Heat Kernel 

      Maks Ovsjanikov; Quentin Merigot; Facundo Memoli; Leonidas Guibas (2010)
      A common operation in many geometry processing algorithms consists of finding correspondences between pairs of shapes by finding structure-preserving maps between them. A particularly useful case of such maps is isometries, ...
    • Persistent Heat Signature for Pose-oblivious Matching of Incomplete Models 

      Tamal K. Dey; Kuiyu Li; Chuanjiang Luo; Pawas Ranjan; Issam Safa; Yusu Wang (2010)
      Although understanding of shape features in the context of shape matching and retrieval has made considerable progress in recent years, the case for partial and incomplete models in presence of pose variations still begs ...
    • Polygonal Boundary Evaluation of Minkowski Sums and Swept Volumes 

      Marcel Campen; Leif Kobbelt (2010)
      Abstract We present a novel technique for the efficient boundary evaluation of sweep operations applied to objects in polygonal boundary representation. These sweep operations include Minkowski addition, offsetting, and ...
    • Polygonal Mesh Watermarking Using Laplacian Coordinates 

      Ying Yang; Ioannis Ivrissimtzis (2010)
      We propose a watermarking algorithm for polygonal meshes based on the modification of the Laplacian coordinates. More specifically, we first compute the Laplacian coordinates (x, y, z) of the mesh vertices, then construct ...
    • Scales and Scale-like Structures 

      Eric Landreneau; Scott Schaefer (2010)
      We present a method for generating scales and scale-like structures on a polygonal mesh through surface replacement. As input, we require a triangular mesh that will be covered with scales and one or more proxy-models to ...
    • Signing the Unsigned: Robust Surface Reconstruction from Raw Pointsets 

      Patrick Mullen; Fernando de Goes; Mathieu Desbrun; David Cohen-Steiner; Pierre Alliez (2010)
      We propose a modular framework for robust 3D reconstruction from unorganized, unoriented, noisy, and outlierridden geometric data. We gain robustness and scalability over previous methods through an unsigned distance ...
    • Trivial Connections on Discrete Surfaces 

      Keenan Crane; Mathieu Desbrun; Peter Schroeder (2010)
      This paper presents a straightforward algorithm for constructing connections on discrete surfaces that are as smooth as possible everywhere but on a set of isolated singularities with given index. We compute these connections ...
