<br>
I've been creating some simple python scripts that help me see a<br>
simple representation of the state of ParaView.<br>
<br>
One thing I wanted was to be able to see what changes had been<br>
made such that a value was no longer the default. Then, I'm going<br>
to print this out at the beginning of my batch animation jobs, which<br>
will then go into the log file generated by the queuing system.<br>
<br>
So here is my function to do that for an object:<br>
<br>
----------<br>
def altered(object):<br>
if (object == None):<br>
return<br>
dup = object.__class__()<br>
for prop in dup.ListProperties():<br>
if (hasattr(object.GetProperty(<u></u>prop), 'GetData')):<br>
if (dup.GetProperty(prop).<u></u>GetData() != object.GetProperty(prop).<u></u>GetData()):<br>
print prop + ": " + str(object.GetProperty(prop))[<u></u>:80] + " [" + str(dup.GetProperty(prop)) + "]"<br>
del(dup)<br>
del(prop)<br>
----------<br>
<br>
And then I can loop over all the sources to get a handy list:<br>
<br>
----------<br>
for src in GetSources():<br>
srcp = FindSource(src[0])<br>
print "********************"<br>
print " " + src[0] + " -- " + srcp.GetXMLLabel()<br>
altered(srcp)<br>
print " ---------------"<br>
print " Representation:"<br>
altered(GetDisplayProperties(<u></u>srcp))<br>
----------<br>
<br>
So the main missing feature for me is trying to show how the sources<br>
are linked together -- basically recreating the pipeline display,<br>
except as ASCII text. But I haven't yet figured out how to<br>
programmatically determine which "sources" are connected to which.<br>
<br>
<br>
The other thing I'd like to be able to do is report what other<br>
field data is available from a file reader -- I can see by looking<br>
in the .pvsm file that that data was saved, so I hope it might<br>
be somehow available via the Python interface.<br>
<br>
<br>
<br>
So here's some sample output from a state file I'm experimenting<br>
with:<br>
