[vtkusers] How to get triangular mesh from reconstruction

[Nikita Kojekine AKA Kitya Karlson]

Hello! I use vtkSurfaceReconstructionFilter to make surface
reconstruction.
Afterwards I use vtkContourFilter to get the surface. How can I get
afterwards it as a 3D triangular mesh, so that I can get
  setofdata=(vtkPolyData *)???->GetOutput();
  vtkCellArray * cells = vtkCellArray::New();
  cells = setofdata->GetPolys();

cells from it and points, and normals for cells?
