Provably Good Surface Sampling and Approximation
(The Eurographics Association, 2003)
We present an algorithm for meshing surfaces that is a simple adaptation of a greedy "farthest point" technique proposed by Chew. Given a surface S, it progressively adds points on S and updates the 3-dimensional Delaunay ...
Filling Holes in Meshes
(The Eurographics Association, 2003)
We describe a method for filling holes in unstructured triangular meshes. The resulting patching meshes interpolate the shape and density of the surrounding mesh. Our methods work with arbitrary holes in oriented connected ...
Approximating and Intersecting Surfaces from Points
(The Eurographics Association, 2003)
Point sets become an increasingly popular shape representation. Most shape processing and rendering tasks require the approximation of a continuous surface from the point data. We present a surface approximation that is ...
Smooth Geometry Images
(The Eurographics Association, 2003)
Previous parametric representations of smooth genus-zero surfaces require a collection of abutting patches (e.g. splines, NURBS, recursively subdivided polygons). We introduce a simple construction for these surfaces using ...
Geometry Compression of Normal Meshes Using Rate-Distortion Algorithms
(The Eurographics Association, 2003)
We propose a new rate-distortion based algorithm for compressing 3D surface geometry represented using triangular normal meshes. We apply the Estimation-Quantization (EQ) algorithm to compress normal mesh wavelet coefficients. ...
3D Reconstruction Using Labeled Image Regions
(The Eurographics Association, 2003)
In this paper we present a novel algorithm for reconstructing 3D scenes from a set of images. The user defines a set of polygonal regions with corresponding labels in each image using familiar 2D photo-editing tools. Our ...
A concise b-rep data structure for stratified subanalytic objects
(The Eurographics Association, 2003)
Current geometric kernels suffer from poor abstraction and design of their data structures. In part, this is due to the lack of a general mathematical framework for geometric modelling and processing. As a result, there ...
A Geometric Database for Gene Expression Data
(The Eurographics Association, 2003)
As the logical next step after sequencing the mouse genome, biologists have developed laboratory methods for rapidly determining where each of the 30K genes in the mouse genome is synthesizing protein. Applying these methods ...
High-Pass Quantization for Mesh Encoding
(The Eurographics Association, 2003)
Any quantization introduces errors. An important question is how to suppress their visual effect. In this paper we present a new quantization method for the geometry of 3D meshes, which enables aggressive quantization ...
Global Conformal Surface Parameterization
(The Eurographics Association, 2003)
We solve the problem of computing global conformal parameterizations for surfaces with nontrivial topologies. The parameterization is global in the sense that it preserves the conformality everywhere except for a few points, ...
