⚠️There's a newer version (2.5) of this package.Take me there.
alphahull (version 2.2)
Generalization of the Convex Hull of a Sample of Points in the
Plane
Description
Computation of the alpha-shape and alpha-convex
hull of a given sample of points in the plane. The concepts of
alpha-shape and alpha-convex hull generalize the definition of
the convex hull of a finite set of points. The programming is
based on the duality between the Voronoi diagram and Delaunay
triangulation. The package also includes a function that
returns the Delaunay mesh of a given sample of points and its
dual Voronoi diagram in one single object.
