Alpha Shapes

Alpha Shape Toolbox is a Python library for generating n-dimensional alpha shapes, which are a generalization of convex hulls used to create bounding polygons around sets of points. It offers workflows to manually define the alpha parameter or optimize its value to best fit the data. As of version 1.3.1 (released April 16, 2021), the library supports 3D input data and GeoJSON output for its command-line interface. It is actively maintained with recent updates addressing Python version compatibility.
