  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Chang, Will; Zwicker, Matthias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present an unsupervised algorithm for aligning a pair of shapes in the presence of significant articulated motion and missing data, while assuming no knowledge of a template, user-placed markers, segmentation, or the ...
  • 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 ...
  • Steinbrecher, Tillmann; Gerth, Maik (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We propose a new method for automatic construction of inlays and onlays. Mesh models from a small tooth library are adapted to the remaining healthy surface of the patient s tooth. In the area above the cavity, the general ...
  • Zhang, H.; Sheffer, A.; Cohen-Or, D.; Zhou, Q.; Van Kaick, O.; Tagliasacchi, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Non-rigid 3D shape correspondence is a fundamental and difficult problem. Most applications which require a correspondence rely on manually selected markers. Without user assistance, the performances of existing automatic ...
  • Li, Hao; Sumner, Robert W.; Pauly, Mark (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a registration algorithm for pairs of deforming and partial range scans that addresses the challenges of non-rigid registration within a single non-linear optimization. Our algorithm simultaneously solves for ...
  • 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 ...
  • 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 ...
  • 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] ...
  • Loop, Charles; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a second order smooth filling of an n-valent Catmull-Clark spline ring with n biseptic patches. While an underdetermined biseptic solution to this problem has appeared previously, we make several advances in ...
  • Ling, Ruotian; Wang, Wenping; Yan, Dongming (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Various methods have been proposed for fitting subdivision surfaces to different forms of shape data (e.g., dense meshes or point clouds), but none of these methods effectively deals with shapes with sharp features, that ...
  • Myles, A.; Ni, T.; Peters, J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
  • Ovsjanikov, Maks; Sun, Jian; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Although considerable attention in recent years has been given to the problem of symmetry detection in general shapes, few methods have been developed that aim to detect and quantify the intrinsic symmetry of a shape rather ...
  • 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, ...
