Constrained Construction of Planar Delaunay Triangulations without Flipping
Structural Mechanics of Engineering Constructions and Buildings, 2018 The construction of Voronoi diagrams and Delaunay triangulations finds wide application in many branches of science. Delaunay triangulations have properties which make them more desirable than other triangulations for the same node set.

Problems, methods and technologies of combined 3D model construction for underwater and above-water relief [PDF]
E3S Web of Conferences, 2020 In the article we describe the methods for construction of underwater 3D relief (bathymetry) and combining it with the corresponding ground relief (terrain) when the bathymetry information is of much lower quality than that of terrain.

Implementing Data-Dependent Triangulations with Higher Order Delaunay Triangulations
ISPRS International Journal of Geo-Information, 2017 The Delaunay triangulation is the standard choice for building triangulated irregular networks (TINs) to represent terrain surfaces. However, the Delaunay triangulation is based only on the 2D coordinates of the data points, ignoring their elevation ...

Mathematics, 2021 Every biological image contains quantitative data that can be used to test hypotheses about how patterns were formed, what entities are associated with one another, and whether standard mathematical methods inform our understanding of biological ...

Excitable Delaunay Triangulations [PDF]
Kybernetes, 2011 PurposeDelaunay triangulations provide a good alternative to existing approaches of modelling unstructured unconventional computers. Experimental research in novel and emerging computing paradigms and materials shows a great progress in designing laboratory prototypes of spatially extended computing devices. In these devices, computation is implemented

A Toroidal Maxwell–Cremona–Delaunay Correspondence
Journal of Computational Geometry, 2022 We consider three classes of geodesic embeddings of graphs on Euclidean flat tori: • A toroidal graph embedding Γ is positive equilibrium if it is possible to place positive weights on the edges, such that the weighted edge vectors incident to each ...

Quasi-Dense Matching Algorithm for Close-Range Image Combined With Feature Line Constraint
IEEE Access, 2022 Point-based sparse or dense matching can typically obtain satisfactory 3D point clouds of general contour features, but the deformation problem at the edges of artificial objects is prominent.

Minimum-error triangulations for sea surface reconstruction
Journal of Computational Geometry, 2023 We apply state-of-the-art computational geometry methods to the problem of reconstructing a time-varying sea surface from tide gauge records. Our work builds on a recent article by Nitzke et al.
