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 ... -
Motorcycle Graphs: Canonical Quad Mesh Partitioning
(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 ... -
Non-Rigid Registration Under Isometric Deformations
(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 ... -
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 ... -
Polyhedral Finite Elements Using Harmonic Basis Functions
(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 ... -

Provably Good 2D Shape Reconstruction from Unorganized Cross-Sections
(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] ... -
Reconstructing Animated Meshes from Time-Varying Point Clouds
(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 ... -
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 ... -
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 ... -
Streaming Surface Reconstruction Using Wavelets
(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 ... -
Surface sampling and the intrinsic Voronoi diagram
(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 ...
