You seem to have a set of points, as input. Surface_mesher in CGAL-3.3 is a 
package to mesh a implicit function. What you need is a surface 
reconstruction algorithm (from a set of points). You cannot use 
Surface_mesher.

However, there exists some algorithm to compute an implicit function, from a 
set of points, whose zero level represents a smooth surface interpoling the 
points. If you have such a function, then you can use the Surface_mesher 
package.
