Triangulations with Circular Arcs

open access: yesJournal of Graph Algorithms and Applications, 2015
An important objective in the choice of a triangulation of a given point set is that the smallest angle becomes as large as possible. When triangulation edges are straight line segments, it is known that the Delaunay triangulation is the optimal solution.

Meshing Unsigned Distance Fields with Regular Triangulations

open access: yesComputer Graphics Forum, EarlyView.
Abstract Unsigned distance fields (UDF) are a versatile, implicit representation of geometry. They can represent surfaces that are not bounding a solid or contain points or curves that are not manifold, for example several sheets meeting along a common curve. Contouring the implicit representation, i.e. turning it into an explicit one, requires finding

Tangent Blow‐Ups for Processing Non‐Manifold Geometry

open access: yesComputer Graphics Forum, EarlyView.
Abstract Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, routinely contains sharp features like edges, corners, self‐intersections, branching junctions, and other singularities, rendering standard methods ill‐defined at ...

A practical algorithm for weighted k‐hulls

open access: yesComputer Graphics Forum, EarlyView.
Abstract The convex hull is a central concept in computational geometry, geometry processing, and generally for summarizing sampled data. Its descriptive power suffers significantly in the presence of noise. The k‐hull, also known as the k‐depth contour in statistics, is the intersection of all half‐spaces that contain all but k data points, i.e. it is

Proximal delaunay triangulation regions

open access: yes, 2015
Peters, James FrancisThis article introduces proximal Delau-nay triangulation regions and strongly near (also called overlap) Delaunay triangles. A main result in this paper is the proof that proximal Delaunay triangulation regions are convex polygons ...

Improved Jitter Elimination and Topology Correction Method for the Split Line of Narrow and Long Patches

open access: yesISPRS International Journal of Geo-Information, 2018
Extracting the split line of narrow and long patches is important for the generalization of land-use thematic data. There are two commonly used methods for extracting the split lines: One is based on Delaunay triangulation and the other is based on ...

SharpEdge: Edge Feature Surface Reconstruction From Space Curves

open access: yesComputer Graphics Forum, EarlyView.
SharpEdge reconstructs surfaces with sharp features from sparse 3D curve networks. By estimating dual normals along curves, our method preserves ridges and corners while producing high‐quality meshes. Abstract Reconstructing high‐quality surfaces from sparse 3D space curves remains challenging, particularly when sharp feature edges are involved ...

Identifying and Mapping Industrial Districts Through a Spatially Constrained Cluster‐Wise Regression Approach

open access: yesJournal of Regional Science, Volume 65, Issue 2, Page 403-428, March 2025.
ABSTRACT The aim of this article is to exploit an innovative spatial econometric approach to map and study the evolving patterns of industrial districts (IDs). The procedure can be classified as a k‐means cluster‐wise regression procedure and is designed to detect homogeneous areas of subcontracting activity.
