surface {tessellation}

Tessellation surface

Description

Exterior surface of the Delaunay tessellation.

Usage

surface(tessellation)

Arguments

tessellation

output of delaunay

Value

A number, the exterior surface of the Delaunay tessellation (perimeter in 2D).

Note

It is not guaranteed that this function provides the correct result for all cases. The exterior surface of the Delaunay tessellation is the exterior surface of the convex hull of the sites (the points), and you can get it with the cxhull package (by summing the volumes of the facets). Moreover, I encountered some cases for which I got a correct result only with the option degenerate=TRUE in the delaunay function. I will probably remove this function in the next version.
