Domain Decomposition for Multiresolution Analysis
(The Eurographics Association, 2003)
This paper describes a method for converting an arbitrary mesh with irregular connectivity to a semi-regular multiresolution representation. A shape image encoding geometric and differential properties of the input model ...
A Geometric Convection Approach of 3-D Reconstruction
(The Eurographics Association, 2003)
This paper introduces a fast and efficient algorithm for surface reconstruction. As many algorithms of this kind, it produces a piecewise linear approximation of a surface S from a finite, sufficiently dense, subset of its ...
Estimating Differential Quantities Using Polynomial Fitting of Osculating Jets
(The Eurographics Association, 2003)
This paper addresses the pointwise estimation of differential properties of a smooth manifold S -a curve in the plane or a surface in 3D- assuming a point cloud sampled over S is provided. The method consists of fitting ...
Stellar Subdivision Grammars
(The Eurographics Association, 2003)
In this paper we develop a new description for subdivision surfaces based on a graph grammar formalism. Subdivision schemes are specified by a context sensitive grammar in which production rules represent topological and ...
Simple Silhouettes for Complex Surfaces
(The Eurographics Association, 2003)
Complex meshes tend to have intricate, detailed silhouettes. This paper proposes two algorithms for extracting a simpler, approximate silhouette from a high-resolution model. Our methods preserve the important features of ...
