Re: [Paraview] vtkCellLocator: Python
Thanks Eric, all,
but this does not seem to work at all. My loop looks something like this:
input = self.GetInputDataObject(0, 0)
output = self.GetOutputDataObject(0)
if input.IsA(vtkMultiBlockDataSet):
iter = input.NewIterator()
iter.UnRegister(None)
iter.InitTraversal()
i=1
while not iter.IsDoneWithTraversal():
curInput = iter.GetCurrentDataObject()
curInformation = curInput.GetInformation()
print i
print iter.GetCurrentMetaData()
# This is where I want to query for the current name, line does
not work
print iter.GetCurrentMetaData().Get(iter.GetCurrentMetaData.NAME)
i=i+1
iter.GoToNextItem();
The output of print iter.GetCurrentMetaData() looks like this:
vtkInformation (0x3808f00)
Debug: Off
Modified Time: 269417
Reference Count: 2
Registered Events: (none)
DONT_PRUNE: 1
NAME: my_given_name
I want to work wit the NAME attribute ('my_given_name in this case)
but I don't know how...?

Hey Bastian,
I think you should be able to just use the Get() method to pull out
that information key. When I want to find current time step
information on some pipeline data (with a programmable filter), which
has information that looks like this:
vtkInformation (0x11dd723d0)
Debug: Off
Modified Time: 70754
Reference Count: 2
Registered Events: (none)
DATA_NUMBER_OF_GHOST_LEVELS: 0
DATA_TIME_STEPS: 0
DATA_PIECE_NUMBER: 0
DATA_EXTENT_TYPE: 0
DATA_NUMBER_OF_PIECES: 1
I can do it with these commands:
pdi = self.GetInputDataObject(0,0)
current_time = pdi.GetInformation().Get(pdi.DATA_TIME_STEPS(),0)
So you might be able to just put NAME() in where I put DATA_TIME_STEPS().
Talk to you later,
-Eric

a method called GetMetaData

What's the desired output for this? You could also fetch the data set to the client and then use the vtk wrapped classes in paraview.vtk to use the cell locator if the class has been wrapped but the fetch operation should be used with caution.

Re: [Paraview] vtkCellLocator: Python
Thanks Andi, I will do this. What I am planning to do is to create a scalr field with some distance information as an output. Another issue: I want to loop oder a multi-block dataset with an iterator in a programmable filter (works) and find out the name of the currently visited block. Is that possible? Thanks.

Mai 2010, 16:59:07 Uhr Betreff: Re: [Paraview] vtkCellLocator: Python Unfortunately some of the locator api is pass by reference and therefore not wrapped by python. Bastian, let us know if you run into missing methods when trying to use the cell locator in python.

Bastian, You can create a cell locator in your programmable filter simply by: locator = vtk.vtkCellLocator() Utkarsh On Fri, May 28, 2010 at 10:22 AM, Andy Bauer andy.ba...@kitware.com wrote: My guess is that you'll want to use a filter to get access to the cell locator.
