Hey again,
Back maybe around PV 3.2, I could load a state file in Python (outside
of PV) which included readers for pvd files. I could find the proxies
for the file readers, and then change the file name, update the
pipeline, and then save or display an animation using the new data
set. I haven't tried this for a while because I'm now working with
Xdmf files, and the reader didn't work with ParaView & Python well
enough until more recently.
Now, when I try the same scripts, the reader on which I change the
file name doesn't show anything at all in the render view. (i.e. I
have two readers in my pipeline -- if I don't change any file names I
can load in the state file and animate fine -- if I change one file
name only that element of my visualization drops out, but I can see
and animate the other -- if I change both names the renderview looks
blank during the whole animation.)
I'm doing something like:
from paraview import servermanger
servermanager.Connect()
servermanager.LoadState("/Users/emonson/Data/StateFile.pvsm")
pm = servermanager.ProxyManager()
reader = pm.GetProxy("sources","OriginalDataSet.xmf")
reader.FileName = "/Users/emonson/Data/NewDataSet.xmf"
reader.UpdatePipeline()
view = servermanager.GetRenderView()
view.StillRender()
I see that in CVS there is a reader.FileNameChanged(), but calling
that doesn't seem to fix it.
Is there something obvious I'm failing to do, or does this look like
this should work?
Thanks,
-Eric
