[Paraview] Animation with pvbatch

[Mathias Winkel]

Dear all,

Finally, I found a solution for my problem. A working example script is 
given below: I am now reading the TimestepValues from my data source and 
setting ANI.AnimationTime and (!) VIEW.ViewTime appropriately.
Still I do not know why GoToNext() etc. do not work from pvbatch. - Are 
they only applicable for the ParaView GUI?

Best Regards,

Mathias

SetActiveView(VIEW)

for idx in range(3):#len(SRC.TimestepValues)):
   print idx, SRC.TimestepValues[idx]
   ANI.AnimationTime = SRC.TimestepValues[idx]
   VIEW.ViewTime = ANI.AnimationTime
   VIEW.StillRender()
   WriteImage("%s%s" % (directory, filenameout % idx))
