From A Medial Surface To A Mesh
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Medial surfaces are well-known and interesting surface skeletons. As such, they can describe the topology and the geometry of a 3D closed object. The link between an object and its medial surface is also intuitively ...
Fast and Robust Normal Estimation for Point Clouds with Sharp Features
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
This paper presents a new method for estimating normals on unorganized point clouds that preserves sharp features. It is based on a robust version of the Randomized Hough Transform (RHT). We consider the filled Hough ...
Computing Extremal Quasiconformal Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Conformal maps are widely used in geometry processing applications. They are smooth, preserve angles, and are locally injective by construction. However, conformal maps do not allow for boundary positions to be prescribed. ...

Growing Least Squares for the Analysis of Manifolds in Scale-Space
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a novel approach to the multi-scale analysis of point-sampled manifolds of co-dimension 1. It is based on a variant of Moving Least Squares, whereby the evolution of a geometric descriptor at increasing scales ...
Flexible Developable Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We introduce a discrete paradigm for developable surface modeling. Unlike previous attempts at interactive developable surface modeling, our system is able to enforce exact developability at every step, ensuring that users ...
Co-Segmentation of 3D Shapes via Subspace Clustering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a novel algorithm for automatically co-segmenting a set of shapes from a common family into consistent parts. Starting from over-segmentations of shapes, our approach generates the segmentations by grouping the ...
Stream Surface Parametrization by Flow-Orthogonal Front Lines
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The generation of discrete stream surfaces is an important and challenging task in scientific visualization, which can be considered a particular instance of geometric modeling. The quality of numerically integrated stream ...
Mean Curvature Skeletons
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Inspired by recent developments in contraction-based curve skeleton extraction, we formulate the skeletonization problem via mean curvature flow (MCF). While the classical application of MCF is surface fairing, we take ...
Radial Symmetry Detection and Shape Characterization with the Multiscale Area Projection Transform
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a novel method to characterize 3D surfaces through the computation of a function called (multiscale) area projection transform, measuring the likelihood of points in the 3D space to be center of radial symmetry ...
