Dear All,

I have a set of points used to construct a closed surface.

vtkPolyData *point_data = vtkPolyData::New();
	point_data->SetPoints(points);
	point_data->Modified();
	point_data->Update();

	vtkSurfaceReconstructionFilter *reconstruct = 
vtkSurfaceReconstructionFilter::New();
	reconstruct->SetInput(point_data);

	vtkContourFilter *contour = vtkContourFilter::New();
->	contour->SetInput(reconstruct->GetOutput());
	contour->SetValue(0, 1);

but I got error saying "cannot convert parameter 1 from 'class vtkImageData *' 
to 'class vtkDataSet *' " (arrow sign)

So what can I do to pass output of vtkSurfaceReconstructionFilter to 
vtkContourFilter? Thanks

Best wishes,
Krista
