Fast Parallel Construction of Smooth Surfaces from Meshes with Tri/Quad/Pent Facets
(The Eurographics Association and Blackwell Publishing Ltd, 2008) -
G2 Tensor Product Splines over Extraordinary Vertices
(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
(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
(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
(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
(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
(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
(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 ... -

Delaunay Mesh Construction
(The Eurographics Association, 2007)We present algorithms to produce Delaunay meshes from arbitrary triangle meshes by edge flipping and geometrypreserving refinement and prove their correctness. In particular we show that edge flipping serves to reduce mesh ... -
Fast Normal Vector Compression with Bounded Error
(The Eurographics Association, 2007)We present two methods for lossy compression of normal vectors through quantization using base polyhedra. The first revisits subdivision-based quantization. The second uses fixed-precision barycentric coordinates. For ... -
Ridge Based Curve and Surface Reconstruction
(The Eurographics Association, 2007)This paper presents a new method for reconstructing curves and surfaces from unstructured point clouds, allowing for noise in the data as well as inhomogeneous distribution of the point set. It is based on the observation ... -
Surface Reconstruction using Local Shape Priors
(The Eurographics Association, 2007)We present an example-based surface reconstruction method for scanned point sets. Our approach uses a database of local shape priors built from a set of given context models that are chosen specifically to match a specific ... -
Bayesian Surface Reconstruction via Iterative Scan Alignment to an Optimized Prototype
(The Eurographics Association, 2007)This paper introduces a novel technique for joint surface reconstruction and registration. Given a set of roughly aligned noisy point clouds, it outputs a noise-free and watertight solid model. The basic idea of the new ... -
Laplace-Beltrami Eigenfunctions for Deformation Invariant Shape Representation
(The Eurographics Association, 2007)A deformation invariant representation of surfaces, the GPS embedding, is introduced using the eigenvalues and eigenfunctions of the Laplace-Beltrami differential operator. Notably, since the definition of the GPS embedding ... -
Symmetry-Enhanced Remeshing of Surfaces
(The Eurographics Association, 2007)While existing methods for 3D surface approximation use local geometric properties, we propose that more intuitive results can be obtained by considering global shape properties such as symmetry. We modify the Variational ... -
Constraint-based Fairing of Surface Meshes
(The Eurographics Association, 2007)We propose a constraint-based method for the fairing of surface meshes. The main feature of our approach is that the resulting smoothed surface remains within a prescribed distance to the input mesh. For example, specifying ... -
Shape Optimization Using Reflection Lines
(The Eurographics Association, 2007)Many common objects have highly reflective metallic or painted finishes. Their appearance is primarily defined by the distortion the curved shape of the surface introduces in the reflections of surrounding objects. Reflection ... -
Dynamic Geometry Registration
(The Eurographics Association, 2007)We propose an algorithm that performs registration of large sets of unstructured point clouds of moving and deforming objects without computing correspondences. Given as input a set of frames with dense spatial and temporal ... -
Generalized Surface Flows for Mesh Processing
(The Eurographics Association, 2007)Geometric flows are ubiquitous in mesh processing. Curve and surface evolutions based on functional minimization have been used in the context of surface diffusion, denoising, shape optimization, minimal surfaces, and ...
