[Paraview] Python Programmable Filter Time Series Source
Here is an example of a programmable filter vis XML that I want to simply print off the various file names or give me and ability to read the file series. I have this python programmable filter set up to work when I click File->Open in ParaView. I have the ability to then chose file series from the file prompt. How might I make a programmable filter via XML attributes so that it can handle file series. The value of this property determines the dataset type for the output of the programmable filter. This property contains the text of a python program that the programmable source runs. This property is a python script that is executed during the RequestInformation pipeline pass. Use this to provide information such as WHOLE_EXTENT to the pipeline downstream. ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
[Paraview] Python programmable filter to process results over time
I'm trying to make a programmable filter to do some post-processing that involves accumulating data from multiple time steps. This isn't really what I'm trying to do but as an example of something that would get me most of the way there say I want to sum up the values of a field over a range of time steps and then display that cumulative sum as a field itself. My googling seems to indicate this is now possible with the programmable filter but hasn't turned up any simple example of how to do it. Does someone have such an example or can someone point me in the right direction on how to do this (if it's indeed possible)?

[Paraview] Python Programmable Filter: Reading unsigned short TIFFs into vtkImageData
Hi paraview list
Based on this blog post: http://www.kitware.com/blog/home/post/534, I am
trying to make a Python plugin (source) that reads a stack of unsigned
short TIFFs (uint16) and outputs 3D unsigned short imagedata in Paraview.
Assigning the geometry to the imagedata works fine (see def
RequestInformation). My problem is that the values of the voxels in the
imagedata is not assigned correct (see def RequestData). According to
Paraview information tab the data type is unsigned short, but when reading
in a known TIFF (8x8 with uint16 values 1..64) the values of the imagedata
are not correct.
I suspect the last line array.SetValue(offset+v, vals.GetValue(v)) is the
problem. Does the vals.GetValue(v) get casted into a Python type int before
stored in the array?
When I print vals.GetValue(v) to a textfile, I can see that I read the
correct values from the TIFF.
Can anybody see what the problem is?
Cheers,
Allan

Re: [Paraview] python programmable filter via xml with multiple input
Ah, sorry I missed that. Yea, if you want to simply use the vtkPythonProgrammableFilter, I'm afraid you'll have to stick with 1 input port accepting multiple connections, rather than separate input ports. Thus, you'll need to change your XML to just have 1 InputProperty, however you can set the multiple_input attribute to make to accept multiple input connections on the same port. InputProperty clean_command=RemoveAllInputs command=AddInputConnection multiple_input=1 name=Input ... /InputProperty Hope that helps.

Re: [Paraview] Python Programmable Filter: Get Filename of Import filter
Hi Pat,
Thank you for your hint! Unfortunately I would need one more step:
The reason is that the last filter after the while loop will return a
vtkFileSeriesReader where I can't find or access the file information
property.
Looking at the doxygen documentation it in principle should have, but
perhaps not everything is wrapped into the ParaView VTK module.

Hi Markus,
You can walk up the filter pipeline from the python programmable
filter like this:
filter = self
while filter.GetInput():
filter = filter.GetInput().GetProducerPort().GetProducer()
print filter.GetClassName()
This is technique is also discouraged :) Filters should be self
contained algorithms and that do not make assumptions about their
upstream connections. But, if it works, it works!

Re: [Paraview] Python Programmable Filter: Get Filename of Import filter
That's right, you're missing the python bindings for
vtkFileSeriesReader. You can get them by importing the proper python
bindings library. Depending on your version of paraview, it will be:
import libvtkPVVTKExtensionsPython
or for paraview 3.10 and earlier:
import libvtkPVFiltersPython

[Paraview] Python Programmable Filter
Hello Can one write a Python Programmable Filter with multiple outputs? I tried the obvious self.SetNumberOfOutputPorts(2), which complained, and in any case, I wonder how it would interact with the GUI option which defines the output Data Set Type. Since there is a single option, I guess I wouldn't be able to define two different ports with different types. Another output option would be a CompositeDataSet with 2 datasets, but it seems the GUI does not let me define the output type to be vtkCompositeDataSet?

Re: [Paraview] Python Programmable Filter
No, it's not possible to write a python programmable filter with multiple output ports. The number of output ports needs to be set in the constructor of the class itself which is too early to be able to set by the user from the panel for any filter. Workaround is producing a multi-block. Utkarsh On Mon, Apr 19, 2010 at 10:05 AM, Favre Jean jfa...@cscs.ch wrote: Hello Can one write a Python Programmable Filter with multiple outputs?

Re: [Paraview] python programmable filter
What does //BTX and //ETX means Begin TCL Exclude End TCL Exclude. VTK was originally wrapped for use with TCL -hence the name choice. The original parser code used BTX/ETX to mark pieces that couldn't be wrapped and should be skipped. ? how to know if a method is automaticlly or not ? Look at the source code. You can usually guess which function are not likely to be wrapped. If they have pointers to structs etc they are usually not wrapped.

[Paraview] python programmable filter
Hi, I am using vtkKdTree in a python programmable filter. I would like to use: void vtkKdTree::FindPointsWithinRadius(double R, const double x[3], vtkIdList* result) but I don't know how to write it in python. I tried the following : coord = (687856,539156,269) result = vtk.vtkIdList() kdTree.FindPointsWithinRadius(100, coord, result) but this doesn't work.

Re: [Paraview] Python Programmable Filter
Jacques, Couple of ways to solve your problem: * Solution One: If you don't want to deal with the fact that your data is a vtkMultiblockDataSet, apply the Merge Blocks filter after each of the Extract Block filters and then connect to the Programmable Filter to to the output from the Merge Blocks and then your current script should work just fine. The Merge Blocks will convert the vtkMultiBlockDataSet to a vtkUnstructuredGrid on which your script is applicable. * Solution Two: input0 = self.GetInputDataObject(0,0) input1 = self.GetInputDataObject(0,1) output = self.GetOutputDataObject(0) input0Block0 = input0.GetBlock(0) input1Block0 = input1.GetBlock(0) output.CopyStructure(input0) outputBlock0 = input0Block0.NewInstance() outputBlock0.CopyStructure(input0Block0) output.SetBlock(0, outputBlock0) outputBlock0.GetPointData().AddArray(input0Block0.GetPointData().GetArray(pressure1)) outputBlock0.GetPointData().AddArray(input1Block0.GetPointData().GetArray(pressure2)) The above script will work if you are extracting a single block using the Extract Block filter. If you want to merge arrays for all the blocks in the input you'll have to iterate over the datasets in the vtkMultiblockDataset.

There is probably a python way to get help more easily, but one way to figure it out is to look at the VTK doxygen documentation for vtkDataObject and it's subclasses, and realize that all (or almost all) of the public C++ methods are wrapped into python and therefore available to use. cheers, Dave On 11/13/08, Jacques Papper [EMAIL PROTECTED] wrote: Thanks a lot Utkarsh !
