I am not sure that this would do the trick, e.g. for extracting a
transversal slice of a 3D array.

But this seems to do exactly what I am looking for, thanks :). There
actually may be another solution, that is to use the VTK library.
However, it is a much more complex package, much more powerful but
maybe too much for what I want to do. The scipy.ndimage module ("Multi-
dimensional image processing") is probably the best solution for me.

Thank you,

Raphael
