The Dirichlet tessellation is described in the help for This function computes the Dirichlet-Voronoi tessellation of X
(see dirichlet)
and extracts the vertices of the tiles of the tessellation.
These vertices are the locations which are locally farthest away
from X, that is, where the distance function
of X reaches a local maximum.
The Dirichlet tessellation of X is computed
using dirichlet. The vertices of all
tiles of the tessellation are extracted. Any vertex which
lies on the boundary of the window of X is deleted.
The remaining vertices are returned, as a point pattern,
without duplicated entries.
