    • 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 ...

    • 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 ...

    • Automatic Registration for Articulated Shapes 

      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 ...

    • 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 ...

    • Dental Inlay and Onlay Construction by Iterative Laplacian Surface Editing 

      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 ...

    • Global Correspondence Optimization for Non-Rigid Registration of Depth Scans 

      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 ...

    • Deformation-Driven Shape Correspondence 

      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 ...

    • 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 ...

    • 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 ...

    • 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] ...

    • Fast Parallel Construction of Smooth Surfaces from Meshes with Tri/Quad/Pent Facets 

      Myles, A.; Ni, T.; Peters, J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • G2 Tensor Product Splines over Extraordinary Vertices 

      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 ...

    • Fitting Sharp Features with Loop Subdivision Surfaces 

      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 ...

    • 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 ...

    • Global Intrinsic Symmetries of Shapes 

      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 ...

    • 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, ...

    • 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 ...

    • Discrete Distortion in Triangulated 3-Manifolds 

      Mesmoudi, Mohammed Mostefa; De Floriani, Leila; Port, Umberto (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We introduce a novel notion, that we call discrete distortion, for a triangulated 3-manifold. Discrete distortion naturally generalizes the notion of concentrated curvature defined for triangulated surfaces and provides a ...

    • ReduceM: Interactive and Memory Efficient Ray Tracing of Large Models 

      Lauterbach, Christian; Yoon, Sung-eui; Tang, Ming; Manocha, Dinesh (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel representation and algorithm, ReduceM, for memory efficient ray tracing of large scenes. ReduceM exploits the connectivity between triangles in a mesh and decomposes the model into triangle strips. We ...
