    • Hierarchical Convex Approximation of 3D Shapes for Fast Region Selection 

      Attene, Marco; Mortara, Michela; Spagnuolo, Michela; Falcidieno, Bianca (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Given a 3D solid model S represented by a tetrahedral mesh, we describe a novel algorithm to compute a hierarchy of convex polyhedra that tightly enclose S. The hierarchy can be browsed at interactive speed on a modern PC ...
    • A Hierarchical Segmentation of Articulated Bodies 

      De Goes, Fernando; Goldenstein, Siome; Velho, Luiz (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a novel segmentation method to assist the rigging of articulated bodies. The method computes a coarse-to-fine hierarchy of segments ordered by the level of detail. The results are invariant to deformations, ...
    • A Local/Global Approach to Mesh Parameterization 

      Liu, Ligang; Zhang, Lei; Xu, Yin; Gotsman, Craig; Gortler, Steven J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel approach to parameterize a mesh with disk topology to the plane in a shape-preserving manner. Our key contribution is a local/global algorithm, which combines a local mapping of each 3D triangle to the ...
    • Maximum Entropy Coordinates for Arbitrary Polytopes 

      Hormann, K.; Sukumar, N. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Barycentric coordinates can be used to express any point inside a triangle as a unique convex combination of the triangle s vertices, and they provide a convenient way to linearly interpolate data that is given at the ...
    • Motorcycle Graphs: Canonical Quad Mesh Partitioning 

      Eppstein, David; Goodrich, Michael T.; Kim, Ethan; Tamstorf, Rasmus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We describe algorithms for canonically partitioning semi-regular quadrilateral meshes into structured submeshes, using an adaptation of the geometric motorcycle graph of Eppstein and Erickson to quad meshes. Our partitions ...
    • Non-Rigid Registration Under Isometric Deformations 

      Huang, Qi-Xing; Adams, Bart; Wicke, Martin; Guibas, Leonidas J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a robust and efficient algorithm for the pairwise non-rigid registration of partially overlapping 3D surfaces. Our approach treats non-rigid registration as an optimization problem and solves it by alternating ...
    • Pointwise radial minimization: Hermite interpolation on arbitrary domains 

      Floater, M. S.; Schulz, C. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we propose a new kind of Hermite interpolation on arbitrary domains, matching derivative data of arbitrary order on the boundary. The basic idea stems from an interpretation of mean value interpolation as the ...
    • Polyhedral Finite Elements Using Harmonic Basis Functions 

      Martin, Sebastian; Kaufmann, Peter; Botsch, Mario; Wicke, Martin; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological ...

    • Provably Good 2D Shape Reconstruction from Unorganized Cross-Sections 

      Memari, Pooran; Boissonnat, Jean-Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper deals with the reconstruction of 2-dimensional geometric shapes from unorganized 1-dimensional cross-sections. We study the problem in its full generality following the approach of Boissonnat and Memari [BM07] ...
    • Reconstructing Animated Meshes from Time-Varying Point Clouds 

      Suessmuth, Jochen; Winter, Marco; Greiner, Guenther (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper, we describe a novel approach for the reconstruction of animated meshes from a series of time-deforming point clouds. Given a set of unordered point clouds that have been captured by a fast 3-D scanner, our ...
    • A smart stochastic approach for manifolds smoothing 

      El Ouafdi, A.F.; Ziou, D.; Krim, H. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper, we present a probabilistic approach for 3D object s smoothing. The core idea behind the proposed method is to relate the problem of smoothing objects to that of tracking the transition probability density ...
    • Spectral Conformal Parameterization 

      Mullen, Patrick; Tong, Yiying; Alliez, Pierre; Desbrun, Mathieu (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a spectral approach to automatically and efficiently obtain discrete free-boundary conformal parameterizations of triangle mesh patches, without the common artifacts due to positional constraints on vertices and ...
    • Streaming Surface Reconstruction Using Wavelets 

      Manson, J.; Petrova, G.; Schaefer, S. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a streaming method for reconstructing surfaces from large data sets generated by a laser range scanner using wavelets. Wavelets provide a localized, multiresolution representation of functions and this makes ...
    • Surface sampling and the intrinsic Voronoi diagram 

      Dyer, Ramsay; Zhang, Hao; Moeller, Torsten (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We develop adaptive sampling criteria which guarantee a topologically faithful mesh and demonstrate an improvement and simplification over earlier results, albeit restricted to 2D surfaces. These sampling criteria are based ...
