Minimum working example 2D Alpha Shapes in Python

[Ravi Peters]

Hi, I'm using the python bindings and I want to use the 2D alpha shape package. Unfortunately, I can't get it to work. I am able to instantiate an Alpha Shape 2:

from CGAL import CGAL_Alpha_shape_2 as AS

a = AS.Alpha_shape_2()

but I don't see a way to put points in the Alpha Shape. It has no insert() method, like for instance the Triangulation classes, nor can I pass a list of Point_2's and a delaunay_triangulation_2 to the constructor, but this results in a NotImplementedError .

What am I missing here?

Thanks,

Ravi

You can either look at the documentation page:
http://doc.cgal.org/latest/Alpha_shapes_2/classCGAL_1_1Alpha__shape__2.html

or checkout the example

examples/python/test_as2.py

You can pass a list of point to the constructor or use
the member function make_alpha_shape

Thanks! that was fast. I completely missed the examples in the source distribution.
