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 ...
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 ...
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 ...
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, ...
Maximum Entropy Coordinates for Arbitrary Polytopes
(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 ...
Pointwise radial minimization: Hermite interpolation on arbitrary domains
(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 ...
Spectral Conformal Parameterization
(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 ...
A Local/Global Approach to Mesh Parameterization
(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 ...
