Triangulations with Locally Optimal Steiner Points
(The Eurographics Association, 2007)
We present two new Delaunay refinement algorithms, the second an extension of the first. For a given input domain (a set of points in the plane or a planar straight line graph), and a threshold angle a, the Delaunay ...
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 ...
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 ...
Data-Dependent MLS for Faithful Surface Approximation
(The Eurographics Association, 2007)
In this paper we present a high-fidelity surface approximation technique that aims at a faithful reconstruction of piecewise-smooth surfaces from a scattered point set. The presented method builds on the Moving Least-Squares ...
A Streaming Algorithm for Surface Reconstruction
(The Eurographics Association, 2007)
We present a streaming algorithm for reconstructing closed surfaces from large non-uniform point sets based on a geometric convection technique. Assuming that the sample points are organized into slices stacked along one ...
Robust Statistical Estimation of Curvature on Discretized Surfaces
(The Eurographics Association, 2007)
A robust statistics approach to curvature estimation on discretely sampled surfaces, namely polygon meshes and point clouds, is presented. The method exhibits accuracy, stability and consistency even for noisy, non-uniformly ...
