New approaches for Delaunay triangulation and optimisation [PDF]

Heliyon, 2019
New techniques are presented for Delaunay triangular mesh generation and element optimisation. Sample points for triangulation are generated through mapping (a new approach). These sample points are later triangulated by the conventional Delaunay method.

3D reconstruction method based on second-order semiglobal stereo matching and fast point positioning Delaunay triangulation. [PDF]

PLoS One, 2022
Binocular vision uses the parallax principle of the human eye to obtain 3D information of an object, which is widely used as an important means of acquiring 3D information for 3D reconstruction tasks.

Variable Density Filling Algorithm Based on Delaunay Triangulation. [PDF]

Micromachines (Basel), 2022
The quality of the filling algorithm in additive manufacturing directly affects the strength of the part. The commonly used 3D printing filling algorithm at this stage is the classic filling algorithm.

DTTrans: PV Power Forecasting Using Delaunay Triangulation and TransGRU. [PDF]

Sensors (Basel), 2022
In an era of high penetration of renewable energy, accurate photovoltaic (PV) power forecasting is crucial for balancing and scheduling power systems. However, PV power output has uncertainty since it depends on stochastic weather conditions.

A Memory-Centric SoC-FPGA Framework for Incremental 2D Delaunay Triangulation

Computers
Incremental two-dimensional (2D) Delaunay triangulation is a fundamental operation in point-cloud processing and surface reconstruction, yet its irregular memory access and dynamically evolving topology make efficient hardware implementation difficult ...

Voronoi diagrams and Delaunay triangulation for modelling animal territorial behaviour. [PDF]

Ecol Evol
We explore the use of movable automata in numerical modelling of male competition for territory. We used territorial dragonflies as our biological inspiration for the model, assuming two types of competing males: (a) faster and larger males that adopt a ...

PROVABLY CONSISTENT DISTRIBUTED DELAUNAY TRIANGULATION [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
This paper deals with the distributed computation of Delaunay triangulations of massive point sets, mainly motivated by the needs of a scalable out-of-core surface reconstruction workflow from massive urban LIDAR datasets.

A Bound for Delaunay Flip Algorithms on Flat Tori

Computing in Geometry and Topology, 2023
We are interested in triangulations of flat tori. A Delaunay flip algorithm performs Delaunay flips on the edges of an input triangulation T until it reaches a Delaunay triangulation.

Good triangulations yield good tours [PDF]

, 2008
Consider the following heuristic for planar Euclidean instances of the Traveling Salesman Problem (TSP): select a subset of the edges which induces a planar graph, and solve either the TSP or its graphical relaxation on that graph. In this paper, we give
