Hello,
 
I'm researching CGAL for 3D Triangulations and surface mesh.

I want to get surface facets and its vertices of the convex hull after
execute 3D Delaunay Triangulation from point sets. How can I do this with
CGAL ?

Please teach me a concrete example code like this:

1. Give the coordinates (x, y, z) of the points to insert. For example, cube
consists of eight points，
    (0, 0, 0), (1, 0, 0), (0, 1, 0), (0, 0, 1), (1, 1, 0), (0, 1, 1), (1, 0,
1), (1, 1, 1)

2. Execut 3D Delaunay Triangulation from these points. 

3. Access all facets, and determine which are surface facets of the cube
model's convex hull. 
   If the facet is surface, output its vertices' cooridnates like p1(x1, y1,
z1), p2(x2, y2, z2), p3(x3, y3,  z3)


In this case, I think I can get 12 facets from cube.  What I think is
correct ?

I am sorry if my English is hard to understand. Please ask if you would like
me to explain something again.
