Starting with a finite set of 3D points, Plotly can generate a Mesh3d object, that depending on a key value can be the convex hull of that set, its Delaunay triangulation or an alpha set. This notebook is devoted to the presentation of the alpha shape as a computational geometric object, its interpretation, and ...
