First thing first: you'll want to split your points up into several
CSV files, one for each time step. In each of the CSV files, you will
list the point positions and the ID, e.g.
path1.csv contains the first time step:
"ID","X","Y","Z"
1,0.0,1.0,0.0
2,1.0,1.1,1.2
path2.csv contains the second time step:
"ID","X","Y","Z"
1,0.0,1.0,0.0
2,1.0,1.2,1.3
and so one.
To animate these files, you will load the entire list of CSV files
through the Open File dialog by navigating to the location of these
files and selecting the group of files labeled "path..csv". Because
the data you are loading is tabular, it will open up a SpreadSheet
view showing you the raw tables. You can close this view as you won't
be needing it. Click back on the default 3D RenderView and then select
the path* source in the Pipeline Browser. To turn these into points,
use the TableToPoints filter, setting the "X Column" property to "X",
the "Y Column" to "Y", and the "Z Column" to "Z".
Now, you'll need to show the points, which aren't visible at this
point. You can add a Glyph filter to display the points with some
geometry. The "Glyph Type" will default to "Arrow", but you can change
that to "Sphere" or whatever your favorite shape is.

Coloring by ID is pretty easy. In the tool bar, color the glyphs by
the "ID" array. Open up the "Color Map Editor" and check the
"Interpret Values As Categories" box. Under "Annotations", click on
the icon with the folder and heart ("Choose preset"). Pick one of the
color map presets for categorical data. Next, click on the toolbutton
just above that with the red, yellow, and blue rectangles ("Add active
values from selected source"). This will assign the ID values to the
colors in the color map.
I hope that gets you going,

Indeed, ParaView does not have such a command in the Calculator filter.

If I understand you correctly, you are describing how only one of the
data arrays from the inputs with the same name is copied to the
output. That is unfortunately the behavior in ParaView 5.4 and prior.
The good news is that the next version of ParaView should instead copy
all the data arrays and mangle the names of the vector field so that
you can have all three distinct vector arrays in the output of the
Append Attribute filter when you do this. See
https://gitlab.kitware.com/paraview/paraview/merge_requests/1639
which added this feature.

Good thinking using the Probe filter (see below), but yep, this won't
quite work.

The Group datasets filter will create a multi block data set, which
won't exactly help you.

This would also be wasteful in terms of memory usage.

I would look at using the Python scripting capabilities within
ParaView for this. You can write a Python script and run it with
pvpython - this is especially useful for running an analysis in a
batch fashion. Within your script you use the Probe filter to get the
data value at a particular location and add that value to some

Hi Jimmy, If you're building Catalyst and want to install for others to link against you will want to enable the PARAVIEW_INSTALL_DEVELOPMENT_FILES CMake option when configuring.

Re: [Paraview] multiple visualization pipeline at a time with co-processing
Hi Ufuk,
I'm guessing the issue is that the calls to Catalyst are not consistent.
Could you share your Python scripts? Also, did you modify them manually?
I tried with PV 5.3. with
the ../ParaView-v5.3.0/Examples/Catalyst/CxxFullExample/ example with the
attached scripts simultaneously by running with "./CxxFullExample
doubleoutputs.py output3.py image11.py" and got the correct output and no
warnings.
Cheers,
Andy

Re: [Paraview] Saving png images in Catalyst-live
Hi, Currently you will need to save the images in the PV GUI during the Live connection. If you need images at specific time steps you will need to set Live breakpoints. I hope to be able to modify Catalyst image output through the Live connection but there are a lot of options that aren't always easy to capture so it will take quite a bit of design work to get right.

Re: [Paraview] [EXTERNAL] Re: long animations are freezing halfway through
Just to give an update, while I couldn't reproduce the issue with Giles example, I was able to do it with another customer. It's quite a curious thing indeed! Still figuring out where to begin to debug this -- the fact that it's a Windows only thing makes it even more tedious -- but will keep you posted.

Re: [Paraview] Dilation Operation ...
Hi Ken, thanks for the reply. From your suggestion, I was playing more with the different output types available, and I am not sure why, but it works now. If I read the data using spherical coordinates checked and the output type set to image, the data is actually read in as 2D lon/lat representation, but with the data represented as cells and not as points. I always believed that with the spherical coordinate settings checked, the output would be represented on a sphere, but its obviously not. Good for me. Thanks again. Cheers, Niklas Niklas, My first question is, are the data actually being read in as a point data field or a cell data field? If you go to the Information panel, what does it say the data are? I'm not at my computer to check this, but I believe that if you read data as a lon/lat projection, the mesh is most likely read as a 2D "image", and if so, that is rendered with the "slice" representation. If that's the case, can you try changing the representation to "surface"? -Ken Sent from my iPad On Jul 5, 2017, at 7:10 AM, Niklas Röber wrote: Dear All, I have a very low resolution netCDF that I would like to visualize as cell data using lon/lat projection. Reading the data using lon/lat projection, the variables are represented as point data (image1). If the data is read in spherical, the variables are represented as cell data (image2). Comparing both, shows that some features are missing in the lon/lat projection, see for example central America and Spain. Applying a PointDataToCellData filter to the point data in lon/lat smoothes these features away completely (image3). Is there a possibility to visualize the data correctly, as shown with spherical projection, but in lon/lat? Or can the point data somehow be dilated so that central America and half of Europe are not "filtered" out? Thanks for any help!
