Hi,
I'm trying to create a table containing several rows of integrated values
for different contours with a programmable filter but I can't see how to use
the Integrate Variables filter. In filters.xml it show as being called
vtkIntegrateAttributes but I cannot create this in python. Also,
Hi,
I would to like to have your advice concerning the display of 2D data. I have
some structure containing x, y positions, connectivity in order to create
triangles, quads, lines, ... and attributes (acceleration, speed,...)
that are associated to nodes.
For the moment I can display
Hey Paul,
I don't have an answer to your problem, but just wanted to point out that
vtkIntegrateAttributes is not part of VTK proper, but is listed on the ParaView
docs pages:

Ah - thanks for the tip!
Does anyone know the way to call this in a programmable filter? Or, is it
even wrapped for python?
Thanks,
Paul

Could you be a bit more clear about what you're trying to do? It sounds like
you're trying to take your contours and integrate some attributes over each of
the contours separately so you get a table which contains as many rows as the
number of contours (and maybe separate columns for each
Hi Eric,
You are right - I would like one row of integrated values per contour. I
don't understand how I can do this without Integrate Attributes though.

I've found out how to access the Integrate Attributes - I can import it
from vtkPVFiltersPython :)

That's great.
This is very rough, but I was thinking of something like this after setting the
programmable filter Output Data Set Type to vtkTable (to test I've created a
Wavelet Source and run it through a Gradient filter, and then a Calculator
which creates a new value called RTGradMag,
Was having trouble doing the sum using numpy instead of the python built-in
sum(), but I figured it out. It's just slightly cleaner this way, but I don't
know which is faster.
Of course, I still don't know if this does what you are looking for, but I
thought I'd pass it along anyway... :) (I
Thanks Eric - unfortunately your calculation won't take into account the
area (my data is coming from an unstructured grid). I've put in my solution
with integrate attributes. It's a bit slow calculating the contour each
time though

Yeah, I wondered if you were needing the area.
If you want to compare the speed you could also try using a Python script
(assigned to a macro button) which sets up this pipeline in the GUI for you
automatically based on your desired contour values, branching out your pipeline
into a bunch of
I have try to inherit the reader plugin from vtkPolyDataMapper2D but the result
is not ok. I don't not yet what vtkObject I should set as an output from the
reader.
For the moment I have always the data that is in 3D in Paraview.
What is the good way to do what I would to do ?
Thanks

You have to be careful of the terminology because in the world of VTK
XML files binary really means base 64 encoded, and appended not
encoded means binary. I have used the following two lines in a code in
order to coax the VTK XML writer to write binary:
