[vtkusers] Problem conversion vtkStructuredPoints to mesh/Polydata

[agatte]

Hi ;)

I am just begining my adventure with vtk. 
I have a  *.vtk file STRUCTURED_POINTS. I want to convert it to POLYDATA and
save as *.vtk  file.

Could anyone help me please ? 


I would appreciate for any help.


I am trying with this code : but I received an error :

int main()
{

try 
{
	 vtkSmartPointer<vtkStructuredPointsReader> reader =
     vtkSmartPointer<vtkStructuredPointsReader>::New();
     reader->SetFileName("Points.vtk");
     reader->Update();
 
    vtkSmartPointer<vtkGeometryFilter> geometryFilter = 
    vtkSmartPointer<vtkGeometryFilter>::New();
	geometryFilter->SetInput(reader->GetOutput);
	geometryFilter->Update();


    /*vtkContourFilter * contour = vtkContourFilter::New();
    contour->SetInput( reader->GetOutput() );
    contour->SetValue(0, 128); */

	// Save mesh as vtk Poly Data
    vtkPolyDataWriter * writerMesh = vtkPolyDataWriter::New();
	writerMesh->SetFileName("MeshVTK.vtk");
    writerMesh->SetInput(geometryFilter->GetOutput());
    writerMesh->Write();

   // contour->Delete();
	writerMesh->Delete();

} 
catch (itk::ExceptionObject &ex) 
{ 
   std::cout << ex << std::endl; 
   return EXIT_FAILURE; 
} 


}
