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

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

Thanks for the clarification. I had tried this with the following error:
vtkPythonProgrammableFilter (0x5458a60): Attempt to connect input port
index 1 for an algorithm with 1 input ports.
I gather that 'SetNumberOfInputPorts()' should be called in the
constructor of the filter, which I gather is
In your example, your XML is setup to provide the inputs on multiple
"ports", while you're code is expecting multiple "connections" on same
port. Use the following script, instead.
print self.GetInputDataObject(0, 0).GetNumberOfPoints()
print self.GetInputDataObject(1, 0).GetNumberOfPoints
Hi,
I am able to run a python programmable filter accessing multiple inputs
selected from the pipe line e.g:
#
numInputs = self.GetNumberOfInputConnections(0)
for i in range(numInputs):
print self.GetInputDataObject(0,i).GetNumberOfPoints()

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

Hello,
it seems if my question formulated in a previous thread
(http://www.paraview.org/pipermail/paraview/2011-November/023318.html) did not
really decribe what I needed.
I do like to get the information of the

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.

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 wou
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.

Thank you Jean.

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()

To print the class name for any vtkobject in python use:

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.

Thanks a lot Utkarsh !
It works. I was almost there, but I couldn't figure out a way to expose the
available interface for each object!
Where am I supposed to look to figure out that CopyStructure(), and
NewInstance(), SetBlock() etc ... are functions available ?
Kind regards,

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 "M
Here is what I am doing at the moment.
-Load geometry 1
-Extract wing block
-Load geometry 2
-Extract wing block
Then use the resample filter with wing1 as input and wing2 as source
(this works)
The last bit is missing (that is merging the data from wing2 with the
resampled data)

Programmable filter can still be made to work. Do the datasets have
multiple parts? I am not sure how resampling would work with multiple
parts. It is impossible to guess which parts map to which parts...

They are multi-block datasets from Ensight Reader.
Is there another way of dealing with this then ?

Hi Berk,
I am trying out your suggestion of merging arrays :
input0 = self.GetInputDataObject(0,0)
input1 = self.GetInputDataObject(0,1)
output = self.GetOutputDataObject(0)
output.GetPointData().AddArray(input0.GetPointData().GetArray("pressure1"))
output.GetPointData().AddArray(input1.GetPointD
