I do literature review for alpha shape algorithm recently.
I think the main idea of alpha shape algorithm is: connecting the points,
which have empty circumscribing sphere
I am confusing about relationship between alpha and radius of sphere
There are some introduction to alpha:
1. In Edelsbrunner's Algorithm, radius of sphere is smaller than alpha
2. In CGAL tutorial, alpha is squared radius of sphere
3. In some other introductions, alpha is the radius of sphere.
Which one is correct?
