  • Li, J. Y. S.; Zhang, H. (The Eurographics Association, 2006)
    Quality meshing in 2D and 3D domains is an important problem in geometric modeling and scientific computing. We are concerned with triangle meshes having only nonobtuse angles. Specifically, we propose a solution for ...
  • Biasotti, S.; Giorgi, D.; Spagnuolo, M.; Falcidieno, B. (The Eurographics Association, 2006)
    This paper sketches a technique for 3D model retrieval built on size functions, a mathematical tool to compare shapes. Size functions are introduced for the first time to discriminate among 3D objects, through the proposal ...
  • Lee, Yunjin; Lee, Seungyong; Ivrissimtzis, Ioannis; Seidel, Hans-Peter (The Eurographics Association, 2006)
    This paper proposes a general framework for overfitting control in surface reconstruction from noisy point data. The problem we deal with is how to create a model that will capture as much detail as possible and simultaneously ...
  • Yang, Yong-Liang; Lai, Yu-Kun; Hu, Shi-Min; Pottmann, Helmut (The Eurographics Association, 2006)
    Geometry processing algorithms often require the robust extraction of curvature information. We propose to achieve this with principal component analysis (PCA) of local neighborhoods, defined via spherical kernels centered ...

    Relating the intrinsic Laplacian to the mean curvature normal, we arrive at a model for bending of inextensible surfaces. Due to its constant Hessian, our isometric bending model reduces cloth simulation times up to three-fold.
  • Varadhan, Gokul; Krishnan, Shankar; Zhang, Liangjun; Manocha, Dinesh (The Eurographics Association, 2006)
    We present a new algorithm to compute a topologically and geometrically accurate triangulation of an implicit surface. Our approach uses spatial subdivision techniques to decompose a manifold implicit surface into star-shaped ...
  • Li, Wan-Chiu; Ray, Nicolas; Lévy, Bruno (The Eurographics Association, 2006)
    In Geometry Processing, and more specifically in surface approximation, one of the most important issues is the automatic generation of a quad-dominant control mesh from an arbitrary shape (e.g. a scanned mesh). One of the ...
  • Tong, Y.; Alliez, P.; Cohen-Steiner, D.; Desbrun, M. (The Eurographics Association, 2006)
    We introduce a framework for quadrangle meshing of discrete manifolds. Based on discrete differential forms, our method hinges on extending the discrete Laplacian operator (used extensively in modeling and animation) to ...
  • Carr, Nathan A.; Hoberock, Jared; Crane, Keenan; Hart, John C. (The Eurographics Association, 2006)
    Many mesh parameterization algorithms have focused on minimizing distortion and utilizing texture area, but few have addressed issues related to processing a signal on the mesh surface.We present an algorithm which partitions ...
  • Karciauskas, K.; Myles, A.; Peters, J. (The Eurographics Association, 2006)
    We describe a subdivision scheme that acts on control nodes that each carry a vector of values. Each vector defines partial derivatives, referred to as jets in the following and subdivision computes new jets from old jets. ...
  • Puppo, Enrico (The Eurographics Association, 2006)
    We introduce RGB triangulations, an extension of red-green triangulations that can support selective refinement over subdivision meshes generated through quadrisection of triangles. Our purpose is to define a mechanism ...
  • Dey, Tamal K.; Sun, Jian (The Eurographics Association, 2006)
    Many applications in geometric modeling, computer graphics, visualization and computer vision benefit from a reduced representation called curve-skeletons of a shape. These are curves possibly with branches which compactly ...
  • Ginkel, I.; Umlauf, G. (The Eurographics Association, 2006)
    In this paper the problem of curvature behavior around extraordinary points of a Loop subdivision surface is addressed. A variant of Loop s algorithm with small stencils is used that generates surfaces with bounded curvature ...
  • Funkhouser, T.; Shilane, P. (The Eurographics Association, 2006)
    Priority-driven search is an algorithm for retrieving similar shapes from a large database of 3D objects. Given a query object and a database of target objects, all represented by sets of local 3D shape features, the ...
  • Hui, Annie; Vaczlavik, Lucas; Floriani, Leila De (The Eurographics Association, 2006)
    We define a new representation for non-manifold 3D shapes described by three-dimensional simplicial complexes, that we call the Double-Level Decomposition (DLD) data structure. The DLD data structure is based on a unique ...
  • Mitra, Niloy J.; Guibas, Leonidas; Giesen, Joachim; Pauly, Mark (The Eurographics Association, 2006)
    We propose a new probabilistic framework for the efficient estimation of similarity between 3D shapes. Our framework is based on local shape signatures and is designed to allow for quick pruning of dissimilar shapes, while ...
  • Simari, Patricio; Kalogerakis, Evangelos; Singh, Karan (The Eurographics Association, 2006)
    Meshes representing real world objects, both artist-created and scanned, contain a high level of redundancy due to (possibly approximate) planar reflection symmetries, either global or localized to different subregions. ...
  • Lipman, Yaron; Cohen-Or, Daniel; Levin, David (The Eurographics Association, 2006)
    In recent years, the moving least-square (MLS) method has been extensively studied for approximation and reconstruction of surfaces. The MLS method involves local weighted least-squares polynomial approximations, using a ...
  • Belyaev, Alexander (The Eurographics Association, 2006)
    A general construction of transfinite barycentric coordinates is obtained as a simple and natural generalization of Floater's mean value coordinates [Flo03, JSW05b]. The Gordon-Wixom interpolation scheme [GW74] and transfinite ...
  • Kazhdan, Michael; Bolitho, Matthew; Hoppe, Hugues (The Eurographics Association, 2006)
    We show that surface reconstruction from oriented points can be cast as a spatial Poisson problem. This Poisson formulation considers all the points at once, without resorting to heuristic spatial partitioning or blending, ...
