[vtkusers] Erode/Dilate with 3D-cross

[Michael S. Vaz]

Hi all,
I would like to perform erotions/dilations on vtkImageData using a
structuring element that I specify.  Specifically, I would like to use the
3D-cross (6 voxels).

As far as I can tell, in vtk 4.2 and earlier we are limited to specifying
parameners of an ellipsoid.  Any suggestions/insight will be much
appreciated.

Thanks,
Sarju

ps: also if someone knows how to write specific scalar values to
vtkImageData (vtk 4.0 please let me know).  Thanks.
