Hi,
I've searched online at length for this and couldn't find the answer, so
hopefully somebody here can help me.
I am trying to create a new VTK object (vtkMultiBlockDataSet) composed of
portions of manipulated data from some other VTK object (in this case, a
vtkStructuredGrid). I then want to delete the vtkStructuredGrid object and
visualize the new vtkMultiBlockDataSet.
So, here's the general outline of what I do in a python script:
newSource = DataGeneratorObject(Program="MB{}")
newSource.UpdatePipeline()
newData = servermanager.Fetch(newSource)
newData.SetNumberOfBlocks(64)
for n in range(0,64):
myData = XDMFReader(FileName=...)
myData.UpdatePipeline()
localData = servermanager.Fetch(myData)
<manipulate the data>
newData.SetBlock(n,vtk.vtkStructuredGrid())
newData.GetBlock(n).DeepCopy(localData)
Delete(localData)
Delete(myData)
newData.DataHasBeenGenerated()
newSource.UpdatePipelineInformation()
newSource.UpdatePipeline()
With all that done, if I try to apply a filter to newSource, it doesn't work.
The data is definitely inside newData -- I can print it out and such, even
after I delete the localData (which is why I used DeepCopy).
But I don't know how to send that data back to the server. Or, maybe I don't
need the DataObjectGenerator -- if that's the case, how do I create a local VTK
object and then send it to the server to visualize?
Hopefully that example is clear... I appreciate any help you guys can provide.
It would be easiest if I could create my own custom reader, but I can't do that
because we use Paraview on a lot of machines that we can't recompile to include
the new plugin.
Thanks,
Tim
