Hi, Everyone.
I am trying to display a slice from a volume dataset, but when I use the
python interface, all I get is a slice of the external surface. Within
paraview's gui, there is no problem selecting "External Surface" vs.
"Internal Volume".
I have tried comparing python traces of slicing entire volume vs. exterior
surface, but the traces are, for all practical purposes, identical. I also
tried looking at a trace of changing the slice's input, but the trace seems
to have no relevant information.
I tried comparing trace state, with no important difference found. I tried
comparing saved state (.pvsm) files, but saw no difference there except for
id kinds of numbers.
I think that ll9cellf523_ncdf (see below) has two output ports, where 0 is
the surface and 1 is the entire volume, but I'm not sure of that. From
"Paraview Scripting with Python" (August 2007), page 15, it looks like I
should be able to:
Slice1.Input = OutputPort(ll9cellf523_ncdf, 1)
But that gives
NameError: name 'OutputPort' is not defined
Trying either
Slice1.Input = ll9cellf523_ncdf.Port(0)
Slice1.Input = ll9cellf523_ncdf.Port(1)
runs, but the slice is still only slicing the external surface.
My test script is below.
Thanks for any help.

view = GetActiveView()
view.Background = [1, 1, 1]
view.ViewSize = [800, 300]
WriteImage("test.png")
p.s., I actually want to do something else (use a calculator to get efield
magnitude, and then plot isocontour surfaces from that), but this slice
example seemed simplest, and I'm assuming that once that works, the other
stuff will work in the same way.
