%description
Implementation in R of the alpha-shape of a finite set of points in the
three-dimensional space. The alpha-shape generalizes the convex hull and
allows to recover the shape of non-convex and even non-connected sets in
3D, given a random sample of points taken into it. Besides the computation
of the alpha-shape, this package provides users with functions to compute
the volume of the alpha-shape, identify the connected components and
facilitate the three-dimensional graphical visualization of the estimated
set.
