Testing simple polygons

open access: yesComputational Geometry, 1997
AbstractWe consider the problem of verifying a simple polygon in the plane using “test points”. A test point is a geometric probe that takes as input a point in Euclidean space, and returns “+” if the point is inside the object being probed or “−” if it is outside.

Self-approaching paths in simple polygons [PDF]

open access: yesComputational Geometry, 2020
We study self-approaching paths that are contained in a simple polygon. A self-approaching path is a directed curve connecting two points such that the Euclidean distance between a point moving along the path and any future position does not increase, that is, for all points $a$, $b$, and $c$ that appear in that order along the curve, $|ac| \ge |bc ...

An Optimal Algorithm for the Separating Common Tangents of two Polygons [PDF]

open access: yes, 2015
We describe an algorithm for computing the separating common tangents of two simple polygons using linear time and only constant workspace. A tangent of a polygon is a line touching the polygon such that all of the polygon lies to the same side of the ...

Stabbing information of a simple polygon

open access: yesDiscrete Applied Mathematics, 1996
The purpose of this paper is to investigate a new combinatorial object describing the structure of a simple polygon and compare it to other well-known objects such as the internal and external visibility graphs, the convex hull and the order type of the vertex set. We call the new object the stabbing information.

Cálculo del área de un polígono simple

open access: yesModelling in Science Education and Learning, 2012
In the present paper we consider to determine the relative position between a point and a simple polygon in a plane. For this purpose we build a model of the polygon, which manipulation carries us, in a very natural way, to the solution of this problem ...

Generalized Petersen graphs and Kronecker covers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
The family of generalized Petersen graphs $G(n,k)$, introduced by Coxeter et al. [4] and named by Mark Watkins (1969), is a family of cubic graphs formed by connecting the vertices of a regular polygon to the corresponding vertices of a star polygon. The

Geodesic-Preserving Polygon Simplification [PDF]

open access: yes, 2013
Polygons are a paramount data structure in computational geometry. While the complexity of many algorithms on simple polygons or polygons with holes depends on the size of the input polygon, the intrinsic complexity of the problems these algorithms solve

Gauss Digitization of Simple Polygons

open access: green, 2021
Digitization is a process of discretizing a continuous object $X ⊂ R 2$ to obtain a digital object $X ⊂ Z 2$. This document addresses the Gauss digitization of continuous objects. In particular, we are interested in computing the digitized object of simple polygons.

Convex Decomposition for a Coverage Path Planning for Autonomous Vehicles: Interior Extension of Edges

open access: yesSensors, 2019
To cover an area of interest by an autonomous vehicle, such as an Unmanned Aerial Vehicle (UAV), planning a coverage path which guides the unit to cover the area is an essential process.
