## What are Voronoi vertices?

Abstract. Given three sites in the plane, a Voronoi vertex is a point that is equidistant from each.

### How do you find Voronoi vertices?

The Voronoi diagram is just the dual graph of the Delaunay triangulation.

- So, the edges of the Voronoi diagram are along the perpendicular bisectors of the edges of the Delaunay triangulation, so compute those lines.
- Then, compute the vertices of the Voronoi diagram by finding the intersections of adjacent edges.

**What are Voronoi edges?**

We know that the intersection of any number of half-planes forms a convex region bounded by a set of connected line segments. These line segments form the boundaries of Voronoi regions and are called Voronoi edges. The endpoints of these edges are called Voronoi vertices.

**What does a Voronoi diagram show?**

points into convex polygons such that each polygon contains exactly one generating point and every point in a given polygon is closer to its generating point than to any other. A Voronoi diagram is sometimes also known as a Dirichlet tessellation.

## How do you draw a Voronoi diagram?

We start by joining each pair of vertices by a line. We then draw the perpendicular bisectors to each of these lines. These three bisectors must intersect, since any three points in the plane define a circle. We then remove the portions of each line beyond the intersection and the diagram is complete.

### What is Voronoi pattern in nature?

A Voronoi pattern provides clues to nature’s tendency to favor efficiency: the nearest neighbor, shortest path, and tightest fit. Each cell in a Voronoi pattern has a seed point. Everything inside a cell is closer to it than to any other seed. The lines between cells are always halfway between neighboring seeds.

**How do you calculate Voronoi edges?**

for each Voronoi vertex v do if v is inside H: v H then Compute radius of circle centered on v and update max. for each Voronoi edge e do Compute p = e H, the intersection of e with the hull boundary. Compute radius of circle centered on p and update max.

**Why are voronoi cells convex?**

In this case each site pk is simply a point, and its corresponding Voronoi cell Rk consists of every point in the Euclidean plane whose distance to pk is less than or equal to its distance to any other pk. Each such cell is obtained from the intersection of half-spaces, and hence it is a (convex) polyhedron.

## How is a Voronoi diagram made?

This type of diagram is created by scattering points at random on a Euclidean plane. The plane is then divided up into tessellating polygons, known as cells, one around each point, consisting of the region of the plane nearer to that point than any other.
