چکیده
|
This work presents the implementation in r of the -shape of a finite set of points in the three-dimensional space ℝ3. this geometric structure 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 α-shape,the r package alphashape3d provides users with tools to facilitate the three-dimensional graphical visualization of the estimated set as well as the computation of important characteristics such as the connected components or the volume,among others.
