When I try just connecting the input I get this error
error C2664: 'void vtkImageAlgorithm::SetInput(vtkDataObject *)' : 
cannot convert parameter 1 from 'vtkImageData *' to 'vtkDataObject *'
1>        Types pointed to are unrelated; conversion requires 
reinterpret_cast, C-style cast or function-style cast

do I need to change this line of code?
        vtkImageToStructuredPoints *i2sp = 
vtkImageToStructuredPoints::New();
        i2sp->SetInput(reader->GetOutput());
