python - Alpha shapes in 3D -

is there "alpha shape" function in 3 dimensions in python, other cgal python bindings?

alternatively, there way extend illustration below 3d?

2d example: draw smooth polygon around info points in scatter plot, in matplotlib

i'm calculating volume using convexhull example, purposes volumes inflated due "convex" constraint.

thanks,
