Thank you,
I think I can reconstruction the surface following Chapter36
"3D Skin Surface Meshing", but the problem is that ,everytime I try to construct a Skin_surface_3 object by a set of points, there's an error like this"CGAL error: precondition violation!
Expr: orientation(p0, p1, p2, p3) == POSITIVE",I wanna know what leads to this error, and if there is anything I can do to solve it.

My purpose is to get a triangulation which is most approach a 3D surface with a set of points of this surface. So hope you can give some suggestions or some examples.
