Get connected points (edges) from a d-dimensional Delaunay Triangulation in CGAL
I have a set of points. I want to calculate the Delaunay Triangulation of them using CGAL and then get the neighbors back.
Input:
p1, p2, p3, p4, ...
Output:
p1-p2, p1-p4, ....
I found answers to this problem for 2 or 3 dimensions. However I need…
