An Algorithm Of Semi-Delaunay Triangulation Of Points Cloud Scattered On Surface

open access: yesComputer Science, 2014
The purpose of the paper is to generalize the Delaunay triangulation onto surfaces. A formal definition and appropriate algorithm are presented. Starting from plane domain Delaunay triangulation definition a theoretical approach is evolved which is a ...

Formal study of plane Delaunay triangulation [PDF]

open access: yes, 2010
This article presents the formal proof of correctness for a plane Delaunay triangulation algorithm. It consists in repeating a sequence of edge flippings from an initial triangulation until the Delaunay property is achieved.

Blocking Delaunay triangulations

open access: yesComputational Geometry, 2013
Given a set B of n black points in general position, we say that a set of white points W blocks B if in the Delaunay triangulation of [Formula: see text] there is no edge connecting two black points. We give the following bounds for the size of the smallest set W blocking B: (i) [Formula: see text] white points are always sufficient to block a set of n

Enviromental data visualisation using Delaunay triangulation

open access: yesJournal of Computer Sciences Institute, 2020
Graphical data representation is very helpful when analyzing environmental data. It allows for discovering trends in data and analysis of phenomena occurring in the area. There are many possibilities to represent such values graphically.

Algorithms for Detecting and Refining the Area of Intangible Continuous Objects for Mobile Wireless Sensor Networks

open access: yesAlgorithms, 2022
Detecting the intangible continuous object (ICO) is a significant task, especially when the ICO is harmful as a toxic gas. Many studies used steady sensors to sketch the contour and find the area of the ICO.

Curved optimal delaunay triangulation [PDF]

open access: yesACM Transactions on Graphics, 2018
Meshes with curvilinear elements hold the appealing promise of enhanced geometric flexibility and higher-order numerical accuracy compared to their commonly-used straight-edge counterparts. However, the generation of curved meshes remains a computationally expensive endeavor with current meshing approaches: high-order parametric elements are ...

Exploration of nature-based biomimetic approach in landscape architectural design: parametric study of candelabra model design

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2020
This research provides an exploration of a biomimetic approach in the process of designing a candelabra model using linear shaped leaves of a Bell flower. The design process described in this research contains two steps: biological and geometrical.

Delaunay Triangulation of Manifolds [PDF]

open access: yesFoundations of Computational Mathematics, 2017
We present an algorithm for producing Delaunay triangulations of manifolds. The algorithm can accommodate abstract manifolds that are not presented as submanifolds of Euclidean space. Given a set of sample points and an atlas on a compact manifold, a manifold Delaunay complex is produced provided the transition functions are bi-Lipschitz with a ...
