vtkImplicitVolume with vtkImageReader

[Dr. Jasjit Suri]

Hi,

I think this pipeline does not work:

METHOD 1 :
vtkImageReader-->vtkImageToStructuredPoints--->vtkImplicitVolume ????


However,

METHOD 2: vtkVolume16Reader--->vtkImplicitVolume does work...


Can any body please tell me if there is an alternative how to use
vtkImplicitVolume with vtkImageReader ?

Thanks very much.

..jas..
