Unbounded Regions of High-Order Voronoi Diagrams of Lines and Segments in Higher Dimensions [PDF]

open access: yes, 2019
We study the behavior at infinity of the farthest and the higher-order Voronoi diagram of n line segments or lines in a d-dimensional Euclidean space. The unbounded parts of these diagrams can be encoded by a Gaussian map on the sphere of directions S^(d-

A Fast Algorithm for Well-Spaced Points and Approximate Delaunay Graphs [PDF]

open access: yes, 2013
We present a new algorithm that produces a well-spaced superset of points conforming to a given input set in any dimension with guaranteed optimal output size. We also provide an approximate Delaunay graph on the output points.

Spatial structure-preserving and conflict-avoiding methods for point settlement selection

open access: yesOpen Geosciences, 2022
Point settlement selection is one of the critical tasks in map generalization, which should consider spatial distribution, spatial conflict, proximity to objects, and other factors.

Omni-Directional Capture for Multi-Drone Based on 3D-Voronoi Tessellation

open access: yesDrones, 2023
This paper addresses the multi-drone formation capture in three-dimensional (3D) environments. The omni-directional minimum volume (ODMV) 3D-Voronoi diagram algorithm is proposed for the first time to achieve the two goals of (1) forming and keeping a ...

Coverage improvement using Voronoi diagrams in directional sensor networks

open access: yesIET Wireless Sensor Systems, 2021
Recently, the area coverage problem has emerged in the directional sensor network (DSN), where the sensor's sensed area depends on its working direction and viewing angle.

Design of porous structure based on the Voronoi diagram and stress line for better stress shielding relief and permeability

open access: yesJournal of Materials Research and Technology, 2023
In the process of artificial metal bone implantation, the mismatch of elastic modulus and bad permeability behavior lead to obvious stress shielding and poor bone tissue ingrowth.

Three dimensional extension of Bresenham’s algorithm with Voronoi diagram [PDF]

open access: yes, 2010
Bresenham’s algorithm for plotting a two-dimensional line segment is elegant and efficient in its deployment of mid-point comparison and integer arithmetic. It is natural to investigate its three-dimensional extensions.

Gridvoronoi: An Efficient Spatial Index for Nearest Neighbor Query Processing

open access: yesIEEE Access, 2019
In this paper, based upon Voronoi Diagram, we propose GridVoronoi which is a novel spatial index that enables users to find the spatial nearest neighbour (NN) from two-dimensional (2D) datasets in almost O(1) time.
