Voronoï tessellation from Delaunay tessellation; this is a list of pairs made of a site (a vertex) and a list of edges.

## Arguments

- tessellation
output of

`delaunay`

## Value

A list of pairs representing the Voronoï tessellation. Each
`pair`

is named: the first component is called
`"site"`

, and the second component is called `"cell"`

.

## Examples

```
library(tessellation)
d <- delaunay(centricCuboctahedron())
v <- voronoi(d)
#> Voronoï diagram with one bounded cell.
# the Voronoï diagram has 13 cells (one for each site):
length(v)
#> [1] 13
# there is only one bounded cell:
length(Filter(isBoundedCell, v)) # or attr(v, "nbounded")
#> [1] 1
```
