[vtkusers] Problem with vtkPolyDataNormals.

[Dimitrios Perperidis]

Hi,

I am using the vtkPolyDataNormals to generate a set of normals for a 
given polydata object:
reader = vtkPolyDataReader::New();
normals = vtkPolyDataNormals::New();

   // Read model image
cout << "Reading model:"<<model_name<<endl;
reader->SetFileName(model_name);

normals->SetInput(reader->GetOutput());
normals->Modified();
normals->Update();
model  = normals->GetOutput();

My polydata object consist of  29328 points. When I use 
vtkPolyDataNormals, the returned polydata object (after 
normals->GetOutput()) consists of 29488 points. It is vital for my 
application to calculate the normals of a vtkPolyData object without 
changing the number of points in the surface.

Any points/ suggestions?

Regards
Dimitrios
