[vtkusers] How to get a triangular mesh (based on Hoppe's Marching Cubes with mesh optimization)

[katefe]

Hi,

i'm trying to get a triangular mesh from a set of points (.ply) based on 
Hoppe's Marching Cubes with mesh optimization. I found this example:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filters/SurfaceFromUnorganizedPoints

that uses vtkSurfaceReconstructionFilter class. But i have 2 questions:

1)Does this class implement also the mesh optimization?
2)Does this class produce a triangular mesh in output? How can i get the 
number of triangles?

Please, help me. Thanks!
