Hi,

I am doing upgrading our software from vtk 5.7 to vtk 6.0. But here is
a very strange problem. Exactly the same code works in vtk 5.7 but not
in vtk 6.0.

The code is the following:
-----------------------------------
std::cout << "before drawing pipeline: mb size: " <<
mb->GetNumberOfBlocks() << "pts: " << mb->GetNumberOfPoints() <<
std::endl;
  vtkPointSet *ps = vtkPointSet::SafeDownCast(mb->GetBlock(0));
  std::cout << "__1 mb: " << mb << "ps: " << ps << " mb size: " <<
mb->GetNumberOfBlocks() << " pts pts:" << ps->GetNumberOfPoints() <<
std::endl;

	{	// Drawing pipeline
		m_Mapper = vtkPolyDataMapper::New();
		m_Renderer->AddActor(m_Actor);
		vtkCompositeDataGeometryFilter *sgfilter =
vtkCompositeDataGeometryFilter::New();
		sgfilter->SetInputData(mb);

		m_Mapper->ScalarVisibilityOff();
		m_Mapper->SetInputConnection(0, sgfilter->GetOutputPort());

		m_Actor->GetProperty()->SetRepresentation(1);
		m_Actor->GetProperty()->SetColor(.7,.7,.7);
		m_Actor->SetMapper(m_Mapper);

    m_Renderer->GetRenderWindow()->Render();

		//sgfilter->Delete();
		//m_Mapper->Delete();
		//m_Actor->Delete();


	}
  std::cout << "after drawing pipeline: mb size: " <<
mb->GetNumberOfBlocks() << "pts: " << mb->GetNumberOfPoints() <<
std::endl;
  std::cout << "__2 mb: " << mb << "ps: " << ps << " mb size: " <<
mb->GetNumberOfBlocks() << " pts pts:" << ps->GetNumberOfPoints() <<
std::endl;
---------------------------------------------------------------------------------------------------------------------

This code, when work in vtk 5.7, we can successfully read in plot3D
and tecplot files;
but when in vtk 6.0, we only can successfully read in tecplot file,
when read in plot3D file, the points data is gone. Please see attached
print screen shot.

I really don't know what is going on here, why the points data is
gone? It is very strange.

Any help is appreciated and thanks in advance.
