Yamamoto,
vtkImageData/vtkStructuredPoints do not support variable spacing.
You could
1: Keep the data in multiple vtkStructuredPoints datasets,
2: Put the data into a vtkRectilinearGrid dataset,
3: Use vtkImageMagnify or vtkImageReslice to make the spacing the same,
then use vtkImageAppend to append them together into one vtkImageData.
