My guess is you're not including vtkStructuredPoints.h, which means the
compiler doesn't know that vtkStructuredPoints is derived from
vtkImageData. Whenever you get this sort of error, check that you have
the necessary includes.

Same thing here, missing include of vtkActor.h (you've only forward
declared somewhere).
