For god's shake, creating a surface from a point cloud it is not about "passing the point set to a function"...There are people that are doing their Phd's(not me, just for the record), in order to tackle the problem in a robust, efficient manner.

All the best in your research efforts but having something out of nothing has never worked...Please try to have the overview and do not get disappointed if it does not work in the first go.

Best regards
Ioannis

As I told you, we (CGAL developers) have code already implemented for that.

There exists litterature about implicit functions computed from a set of
points, but it is not implemented in CGAL.

 The vertices defined by x,y and z coordinates
  x1 y1 z1
  .. ...
  xN yN zN

are already on the surface or extracted from the surface (noise free). I just need to do 3D surface meshing using these coordinates. After reading these coordinates from a text file I am having problem to pass them on to the function

Surface_3 surface(sphere_function,              // pointer to function
                    Sphere_3(CGAL::ORIGIN, 2.)); // bounding sphere

I am not sure how to use the pointer to the function. I guess the 'function' should be a 3D coordinates. How could I use these points in surface meshing?
