Hello all,

I've managed to create a mesh from a point set using the Poisson
reconstruction example.

I'm interested in meshing only a portion of this surface though rather than
the entire thing (for the purposes of hole filling).

In the  documentation on mesh generation
<http://doc.cgal.org/latest/Surface_mesher/index.html#SurfaceMesher_section_criteria>
  
I noticed this: "The meshing algorithm requires to know the surface to be
meshed only through an oracle able to tell whether a given segment, line or
ray intersects the surface or not and to compute an intersection point if
any. This feature makes the package generic enough to be applied in a wide
variety of situations."

and hoped it meant I was able to give it a small starting mesh and it return
a corresponding mesh which intersects the implicit surface. I'm a little
confused on how to implement this though, all the implicit surface functions
seem to use a bounding sphere, suggesting to me the whole surface will be
meshed.

Can anyone provide a small sample of code to put me on the right track?

All help greatly appreciated,

Wiredchop
