Marco and Utkarsh, Thank you!

I just installed ParaView on a different computer. On this computer I 
get no problems with the surface+edges mode. I did not think that it 
could be a problem related to the hardware/driver since the structured 
grid is more or less quite simple. The problem arise on my laptop with a 
Nvidia Quadro FX 770M. I am trying to update the graphics card driver first.

After installing an update of the driver, the artifacts disappeared!

Thanks again for for your help!

Hi,

I wonder if the problem is with Fetch(). What does the following yeild?

ExtractSubset0.UpdatePipeline()
print ExtractSubset0.GetDataInformation().GetNumberOfPoints()

Subject: [Paraview] Saving pipeline object data as a .csv
Message-ID: <CAJC7CwYyzHeTX1V=KFYgc7=Bp8i4FH0XZUL3+uZrHXCWk14HPQ@mail.gmail.com>

Hello all,

I'm experiencing an issue that I'm fairly sure is just a simple option that
I have to change within my script or preferences

When I save a filtered pipeline object(let's say a MeshQuality of an
ExodusII file), as MeshData1, the program will automatically generate
hundreds of .csv files. Most of them will be blank. For example, with a
mesh file with 339645 elements, will save a file MeshData1k.csv in
increments of 37116 for k = 0,1,2,3,...,9. It will also save 90 blank files
afterwards.

I would simply concatenate the tables but I have mesh files of radically
different geometries and materials blocks that I need to script; these end
up having different total mesh elements so the k range will not be the same
and the blank files also differ.

Thanks

The sphere source has a hardcoded limit of 1 million triangles for some
reason .

Plugins/MantaView/VTK/vtkMantaTestSource will generate as many as you want
in parallel. The dataset is kind of nonsensical though, just a long strand
of randomly jittered triangles.

More recently I came up with the attached script that you can tune various
parameters of to get something that more closely represents typical
scientific data. I plan to push it into benchmark.py the next time I have
an opportunity to benchmark ParaView.

The logs do not indicate whether what kind of context the rendering takes
place in. That would be a welcome addition. Until then, follow Burlen's
suggestions and take a look at the VTK level test
vtkRenderingOpenGLCxx-TestFBO which spits out all kinds of useful
information.

Subject: [Paraview] Possibilities of using different color ramps for
 different extractions of the same dataset?
Message-ID: <1415071039128.66490@masonlive.gmu.edu>

Dear all,

I am creating extractions from a NetCDF data. I am wondering if I can create separate color ramps for different extractions of the same array for comparisons.   I tried the process within Paraview Desktop but I was not able to set different color ramps because the array name is the same for all extractions.


Sample code:

 SetActiveSource(ncreader)
    ExtractSubset1 = ExtractSubset()
    ExtractSubset1.VOI = [0, 50,0, 50,0, 8]

    DataRepresentation1 = Show(ExtractSubset1)
    DataRepresentation1.Representation = 'Volume'
    DataRepresentation1.ColorArrayName = ('CELL_DATA', varname)
    DataRepresentation1.ColorAttributeType = 'CELL_DATA'
    DataRepresentation1.LookupTable  = GetLookupTableForArray(?varname...



Any suggestions?


Thanks,

Jing

Your question obviously has to do with python scripts, however in ParaView this can be done using the Calculator filter.  We just create another copy of the data with a different name ? and then ParaView will allow you to use a different color table for this second array.  Could you do something like that?  Or, did I miss your point?

Yes.  I just checked the Calculator function and it seems worked.  I will try to experience more with the tool.

Subject: [Paraview] Data set Size limit in ParaView/HDF5
Message-ID: <2384A91D-BD55-4521-8397-C535CED4D872@bluequartz.net>

The current version of ParaView (4.2.1) uses a fairly old version of HDF5 (API version 1.8.9). This version has a nasty bug on OS X that will not allow HDF5 to read a data set that is larger than 4GB (2^32). This is due to a bug in the configuration process that incorrectly identifies a "size_t" as being unsigned 32 bit integer on Darwin instead of a 64 bit unsigned integer. What is the possibility of getting a newer HDF5 included in ParaView for the next release?

BTW. a new release of HDF5 is coming in a few weeks. This would make a great opportunity to get this fixed with the latest version of HDF5.

Thanks

Thanks for getting the bug report in. I was poking around the ParaView source and it does not look straight forward at all to substitute in a prebuilt HDF5 library (system hdf5). I can not even find the CMake Variables that might let me do this. I tried so simply substitute the latest stable HDF5 into the source tree but as I figured CMake threw lots of errors. If you give me a gentle nudge I might be able to help a bit. We are really being held back by this with our current data sets.

Thanks

Mike,

Are you talking about updating the HDF5 in ParaView source itself or
in the binaries we distribute?

Subject: [Paraview] Sparse Cell Data in a 3DCoRectMesh
Message-ID: <739B83A0-AFA1-48AF-B659-BE596E5D7731@purdue.edu>

Hello,
I have a set of sparse cell data that i want to visualize as cells.
the idea is :
1 create a 3d corectangular grid
2 create a subset grid
3 assign attributes to the new subset
I want to select the cells that contain data utilizing a subset of grid. Utilizing the xdmf website wrote this peace of code

<?xml version="1.0"?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd"[]>
<Xdmf>
 <Domain>
 	<Grid Name="hole domain" GridType="Uniform">
    		<Topology TopologyType="3DCoRectMesh" Dimensions="2  2  3"></Topology>
    		<Geometry Type="Origin_DxDyDz">
      			<!-- Origin -->
      			<DataItem Dimensions="3" NumberType="Float" Format="XML">0 0 0</DataItem>
      			<!-- DxDyDz (Spacing/Resolution)-->
      			<DataItem Dimensions="3" NumberType="Float" Format="XML">1 1 1</DataItem>
    		</Geometry>
	</Grid>

    <Grid Name="Portion" GridType="Subset" Section="DataItem">
	<!-- Select 2 cells from another grid. Which 2 are defined by the DataItem -->

            Format="XML">
            0 2
        </DataItem>

        <Grid Name="Target" Reference="XML">
            /Xdmf/Domain/Grid/Grid[@Name="hole domain"]
        </Grid>
        <Attribute Name="New Values" Center="Cell">
            <DataItem Format="XML" Dimensions="2">
            100 150
            </DataItem>
        </Attribute>

    </Grid>

</Domain>
</Xdmf>

Unfortunately wasn?t able to make it work

Any Idea and/or help would be appreciated

Thanks

I was trying to directly update the source codes then compile my own. That didn't work. I was able to build ParaView 4.2.0 against my installed HDF5 (1.8.13) and have it create the package in the /Applications BUT not all the libraries got "fixed up". The Qt libraries and my HDF5 libraries did not get their "install_name" fixed. 

Do I need to build from the "SuperBuild" to actually create a new package I can give to my employees?

Thanks

Yes, to create "redistributable" binaries, Superbuild would be the way
to go. The ParaVIew superbuild already uses hdf5 1.8.9 Do you know if
that recent enough?

Message-ID: <99315C402367A747A66CC1A61AB72D6993F81FAC@msgdb11.utad.utoledo.edu>


hi-  i have seen this question on various blogs, but not the answer in a usable form for me...
i provide project data to paraview via vtk legacy files in ascii.  the default color mapping functions provided by paraview do not decouple opacity from color, so i am providing my own look_up table of RGBa values organized in such a way that i can apply different opacities to the same color, and different colors to the same opacity.  it works for surface rendering, but not for volume rendering- i.e. when choosing the volume option, the rendering reverts back to one of the default tables.  how do i apply my scalar color table in the vtk file to volumes?
i could laboriously enter 120x4 values into the paraview mapping editor, but that seems silly...
thank you!
and as i am new to paraview and this list mail option, feel free to refer me to an old post.

Not recent enough. I think that was the version where I found the bug for Darwin systems which limited it to 4GB data sets. That version is also about 2-3 years old. HDF5 1.8.13 is the latest. 1.8.14 is coming out in few weeks.

PS: We are just trying to get everyone to build ParaView on their systems. The issue with the SuperBuild is that you can not seem to set an "external" hdf5 build. It will always use the bundled version.

There's a topic awaiting review to fix that. So you should be able to
use "external hdf5" soon.

        I'm a fresh man in paraview.I use the paraview by the way of compiling.I want to use paraview to realize the rendering of large data .
        But now I find a problem .when I use paraview in paralleling ,it seems that  the first node's pressure is very big .It should use more than the size of the data ,but the others node only use a little memory .So in this way ,it dosen't share the datas to all the node,I use many computers ,but it can't mange large datas .The first node should read all of the large data.So I suspect that what the use of  paraview's parallel . 
        I read some news of your paraview ,you say that it can deal with large datas .I want to konw how to do it .I have compiled the paraview's source code with cmake,mpi ,qt,python cuda .And I have used the mpi to realise the parallel.In the client of mpi ,I can see many nodes , and I use the nfs to share files ,all the nodes can read files in a computer.Then i want to konw what the problems of my configuration .Who can help me .Thank you.

Hi Mark,

vtkGDALVectorReader has been in the ParaView source tree for quite a
while. You however have to explicitly turn on the reader by CMake
configuration (Module_vtkIOGDAL) and build ParaView with
GDAL. Furthermore, you need to write a simple XML plugin and load it
to expose the reader to the ParaView GUI. If it works, you can use
GDALVectorReaderSM.xml in the vtkgis_vector_reader repository instead.

Message-ID: <CAPMgRLQk-4OC7h=8Zvso2OBK3tiM2XGdPeq4_fV41pnu0Eto9g@mail.gmail.com>

I'm trying to install paraview from source using:

CC=clang CXX=clang++ CXXFLAGS="-nostdinc++ -stdlib=libc++
-I${LIBCXX_INCLUDE} -L${LIBCXX_LIB}" cmake $PV_SRC \
    -DBUILD_DOCUMENTATION:BOOL=ON \

Everything works fine up to the point where it tries to compile
VTK/ThirdParty/netcdf:

A make VERBOSE=1 reveals that CMake does not pass the CXXFLAGS I've
specified when compiling netcdf.cpp. Since the include directories of the
standard library are missing, compilation fails.

Am I setting the compilation flags correctly (CXXFLAGS, DCMAKE_CXX_FLAGS,
DMPI_CXX_FLAGS..) ?

How do I pass a group of flags to all translation units?

Message-ID: <545B88E9.2080306@geomechanica.com>

Hi All,

I have a program that outputs data to be visualized in paraview in the 
vtu file format. Whenever anyone is viewing this data they always use a 
specific filter. I was wondering if there is a way to specify this 
filter in the input file so that they do not need to apply in every time 
they open a new file. Thanks for your help.

Hi Mark,

vtkGDALVectorReader has been in the ParaView source tree for quite a while. You however have to explicitly turn on the reader by CMake configuration (Module_vtkIOGDAL) and build ParaView with GDAL. Furthermore, you need to write a simple XML plugin and load it to expose the reader to the ParaView GUI. If it works, you can use GDALVectorReaderSM.xml in the vtkgis_vector_reader repository instead.

Hello,

I?m working in the area of Numerical Computational Engineering and we  
want to use Paraview to visualize our simulation results. To add a  
scene from Paraview to a documentation we need to export this scene to  
a PDF-file. At the moment if we export, a PDF-file will be created,  
but opening this file an error occurs, the scene is grey-coloured and  
transparency is gone. I hope you could help me exporting a  
well-working PDF-File.

Greetings

To test if paraview is using the entire set of nodes:

* connect the client to the pvserver mpi job,

* open up views->Memory inspector.
You should then see as many processors as their are on the system, plus the
client.

Next create a Sources->Sphere and apply the Filters->Process Id scalars
filter. There should be as many colors on the sphere as there are
processors in the server. Increase the resolution on the sphere source if
you have more than 8 nodes.

* next open up your data file and use the the memory inspector and process
id scalars filters to see how the reader chose to distribute the data. If
it is all loaded on process 1, apply the D3 filter to redistribute it
amongst all ranks.

hope that helps

What settings are you using for the export? This wiki page explains what
the options do, and what the limitations of the exporter are:

http://www.paraview.org/Wiki/ParaView/Vector_Graphics_Export

The grey coloring sounds like there's a texture mapped surface being
rendered, which cannot be exported unless the data is rasterized.

Hope this helps,

Daniel,

Paraview (under the FILE drop-down menu) has a SAVE STATE/LOAD STATE 
feature.

One starts by loading simulation results, Next, one uses the imaging 
capabilities and filters to get the information displayed that 
highlights the significant results. The final step is to use the FILE > 
SAVE STATE command; PV will write out the information it needs to 
recreate the desired display.

When the FILE > LOAD STATE feature is used, it will first ask if the 
input results file (recorded by the SAVE STATE command) is the results 
file you want to use or do you want to access a different version of the 
simulation. Next, PV will proceed to read the designated simulation 
results file and recreate the desired display.

The ExodusII reader produces a multiblock dataset that can have empty
blocks. As a result, those empty blocks get saved as blank csv files.
You can apply the ExtractBlock filter to only pass through blocks of
interest and then save that result, instead.

To the best of my knowledge, the current volume mappers in
VTK/ParaView need to use a color/opacity transfer functions. Aashish,
is that changing with the new volume rendering code?

Subject: [Paraview] multiple files with different geometries
Message-ID: <CACc+OTko6-S_BHJbDJS=TFuxN7iJY=Mtv-mg+hYT7S9gtHq-ZA@mail.gmail.com>

Hi,


I want to see the data of two .vtk files in Paraview.
One of the file is surface data (topography from SRTM, 45 000 points
polydata) and the other one is a kernel file (20 millions points
unstructured grid). I want the surface data on top of my kernel data.
I can see each of them separately but not together. I thought it was due to
their different geometries (x y z range) and I have applied a transform
filter to translate the surface data but still, I cannot see the two
dataset together: when I put Visible 'on' for the kernel data, my surface
data disappears..


How can I deal with that?


thank you,

Julie

I should also point out that i have tried the import/export options on the color table editing feature- opacity is not preserved.  i.e. when i export a table to an xml file, the opacities all revert to 1.0, and when i import an xml file, any ' o="x.xx" ' value is ignored, and whatever opacity function in the editor from previous work is applied instead.
cheers-

To the best of my knowledge, the current volume mappers in
VTK/ParaView need to use a color/opacity transfer functions. Aashish,
is that changing with the new volume rendering code?

that is indeed annoying, and would be very nice to be able to save the 
opacity table. A work around is use a state file. The opacity tables 
will be saved/restored. note: 4.2 has a bug in state file loading re: 
time. depending on your scenario you may need to use 4.1.

Yes, that's a shortcoming of the current implementation. We'll plan to
fix this by 4.4 or sooner.

I will write it up.  I found another bug in there.  

With regards to the state file loading and time bug, that has been fixed in Master (or the Nightly installs, take your pick).

Dear All

I use ParaView GUI to read in a 3D scalar field on a structured grid. I would like to calculate its gradient, and then the curl of this gradient in each voxel using ParaView. Can you provide examples or indicate the sequence of filters that should be used?

Hi!

I'm looking into Paraview for the analysis of time series of satellite
images. I've followed the tutorial and now wonder how to
open a set of sequential tif (actually geotif) images.

I've been googling and searching the list archives but what I find is
very old and not easy to follow.
Could anybody provide me instructions (or point me to the appropriate
documentation) on how to open a set of images as
a time sequence?

Also, is there anybody out there using Paraview in Remote Sensing applications?

Thanks

Agus

Would (in linux)
convert *.tif image.gif
animate image
be of help?

Do you mean outside Paraview, using convert and animate from the
ImageMagick package?
I'm looking for a way of doing this within Paraview.

I've realized that I can select multiple tif files at Open. Then I can
click the Play button and see the time increasing,
but the actual display does not change, I see the image on top of all
the stack only.

Also, is there perhaps a way of converting the stack of tif images
into a format that could be more efficient
for Paraview?

Thanks

Message-ID: <CAOujwNGtzyUhvXCQG++uO7p9GFmpdOX9B=QvnX9Fdd76WA9mRQ@mail.gmail.com>

Hi. I am doing a custom made FEM solver in one of my studies.
I have a 3D geometry that I save as a VTU file and do my computation on.
To impose boundary conditions I would like to be able to select the edge
faces of cells on the boundary of a geometry in ParaView. Then I would like
to save the selection as a sort of "list of edges" inside the VTU file i
export.

I know how to select points, and cells, but how would i easiest select cell
faces?
When I have selected the cell faces, how do i export them so that my FEM
program can read it?

Augustin,

Have you looked here?

http://www.itk.org/Wiki/ParaView/Users_Guide/Loading_Data

As a once upon a time user of the *.vtu format, this approach worked for me.

(I now use EnSight-formatted simulation results file-sets. This format 
works extremely well for my purposes.)

Tried that. I can see the group in the Open dialog, I select the group
and get it in the Pipeline Browser. But when I click on Apply, I get
an error:

ERROR: In /home/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/IO/Image/vtkTIFFReader.cxx,
line 1116

vtkTIFFReader (0x594d4c0): Problem reading slice of volume in TIFF file.

This does not happen when I read the same files individually, which I
can display correctly.

If I select Play, I get the same message several times and the display
is like noise.

Is there any way I can save the set of tif files as vtu ?

Thanks

Agus

Have you tried just loading a sequence of numbered images? If you name
your files something like image_0.tif, image_1.tif, image_2.tif, etc.,
ParaView will group those files in the browser, and if you open that
group, ParaView will treat it as a time sequence. (The name can be
anything as long as there is a number before the extension, so you can
change "image_" to anything you want, add digits to the numbers such as
000, 001, 002, etc., and start at a different number like 1.)

This is just a guess, but the first thing I would check for is to make
sure that the image metadata such as the resolution of the images is
consistent across all the files. If the dimensions of the image changes
that could wreck havoc on VTK's extent mechanism.

The procedure suggested by Samuel and Kenneth works: it seems I have
some problem
with the particular set of tif files I was using for testing, but I?ve
found that it works in other cases.
I'll try to find out what makes these tif images different.
Thanks

No, it is something related to the individual files, not with the fact
of opening them
as a sequence. Those images giving error at opening them as sequence also
cause the same error if individually opened.
(I actually provided a wrong information in one of my previous
messages: because of
the naming convention requirement,  I was using a set
of images for the sequence and another one for the individual loading,
and they happen to have
some difference).
I'll open another thread as this problem is not related to opening the
sequence and my problem at openeing the
sequence has been solved.
Thank you all for your help.

Message-ID: <CAF5M-Cni6fAZMcWma4vd26WOfYBpL=42HVaZTR-esP7OocmhCQ@mail.gmail.com>

Hi,

I need to run ParaViewWeb in Windows OS, I have no issue to get it run from
Windows with single GPU card (using pvpython). How can I run it should I
add another GPU ?

Information from here ->
http://www.paraview.org/Wiki/Setting_up_a_ParaView_Server shows that to
make use of 2 GPUs, I need to use pvserver. Can I know what is the command
to up pvserver from one node and make use of 2 GPUs cards (mpiexec in
windows) ?

Is the -display option work for windows ?

Thanks for your help.

Message-ID: <CAPzem0=k_AdCOb0Xo5v4vndAF_UxH4uE0k4ebKz0QVYSmP2Adg@mail.gmail.com>

Hi

I am using a calculator filter to get the y co-ordinates for a series of
particles. I am then using that data to color by y position. However this
color is changing over time as the particles move. I would like to "lock
in" the first value, ie the original y position of the particles. Is this
possible?

Is there a function in the calculator or maybe a filter I can add to make
sure the calculator data table isn't updated at every time increment?

cheers,
Tim

Hi,
I would like to load a text file, like a csv, delimited by tab instead of comma.
If I modify the property Field Delimiter Characters to \t in the gui nothing happens (I have only 1 column). From the Python shell I can see that the property is actually set to '\\t', and if I set it manually to '\t' the file is then imported as expected.
Is there a more direct way to achieve the same from the Paraview interface?
Thank you

Subject: [Paraview] EnSightReader: Change input file
Message-ID: <54621190.8080107@tu-braunschweig.de>

Hi all,

I want to apply the same pipeline to a series of Ensight data files in 
order to save extractions in a different format. For the first file, 
this works fine. For the second file, I thought I could change the input 
file by changing the CaseFileName attribute:

reader.CaseFileName = nextfile

But when I run

reader.UpdatePipeline()

I get a segmentation fault. This depends neither on the file, nor on the 
pipeline following.

I tried a workaround by building up a new pipeline for each file. It 
works, and as I have only two files by now, it is ok to do that, but for 
more files, memory usage would explode. Therefore, my question is: Is it 
possible only to change the input file of the EnSightReader, while 
keeping the pipeline?

Kind regards
Ian

Hello,
I'm new with ParaView and would like to visualize large dataset.
My data are in a large file in CSV format (x,y,z,val)
If I would use the memory of two server it is better to split the single
file in two but I suppose it's necessary to convert the CSV file into a
XML format.
Can you help me to solve the problem?

I use paraview client/server, the server is a cluster where I use MPI to
run the pvserver

Thank you in advance,
Fedele Stabile

Subject: [Paraview] Scale Data over Entire Time Range
Message-ID: <1415745911857.32892@ufl.edu>

Hello,


I am using python to control Paraview via a script. I see that Paraview can scale a data set by the entire data set in a time series. If I use the Python trace function in Paraview it does not show how it determines the max and min values of a variable over the entire data set. It just rescales by some numbers(which I assume it computed at some point).


My question is: Is there a function that I can call to get the max and min value of a variable in a data set over all times? Or maybe just get the max and min of a variable in a data set, and I will loop over all times and find the largest and smallest values.

Thank you,

Thanks!

Alan

Hi Alan,
We are working with a large mesh that has side sets defined by string names and
not integer values.  Does Paraview assign an integer if value to the side set and if so,
how does it assign the id and is there a way to extract that from paraview?
Thanks!

Hi Alan,

> Thanks!

The Exodus reader generates a multiblock dataset with one toplevel block containing all the side sets. The index of a side set inside that toplevel block is an integer and can be obtained in a Python programmable filter. The advantage of this is that it's cheap, storage-wise. The disadvantage is that the index will vary depending on what side sets you choose to load.

The Exodus reader can also provide a cell array identifying the side set ID (an integer stored in the Exodus file). See

  http://vtk.org/gitweb?p=VTK.git;a=blob;f=IO/Exodus/vtkExodusIIReader.h;h=10de0366f262732d333ba45187917228d428c21e;hb=HEAD#l112

for more information. I believe this is exposed in ParaView, but forget what the button is called... it used to be "Generate ObjectIds" but someone  decided that was unclear and was going to change it to something that *I* think is unclear. :-)

The advantage of the generated IDs is that they do not vary depending on what you choose to load. The disadvantage is that it is not stored on the block, but on each cell in the block, so it takes up a lot of memory.

Dear Paraview users,

I found an unexpected behavior in Paraview 4.2.
When I set separated panels or other options except the combined one, I
don't get what it is expected and 6 grayed button (restore, update) appear.

I think I fixed it by adding the following lines to pqPropertiesPanel.cxx
in the setPanelMode method:

  // added to avoid unwanted update restore buttons

  this->Internals->Ui.PropertiesSaveAsDefaults->setVisible(has_source);

  this->Internals->Ui.PropertiesRestoreDefaults->setVisible(has_source);

  this->Internals->Ui.DisplaySaveAsDefaults->setVisible(has_display);

  this->Internals->Ui.DisplayRestoreDefaults->setVisible(has_display);

  this->Internals->Ui.ViewSaveAsDefaults->setVisible(has_view);

  this->Internals->Ui.ViewRestoreDefaults->setVisible(has_view);


Moreover I modified the paraview main window to setup the panels. i.e.
for ALL_SEPARATE:

    case vtkPVGeneralSettings::ALL_SEPARATE:

        this->Internals->propertiesPanel->setPanelMode(
pqPropertiesPanel::SOURCE_PROPERTIES);

// added

        this->Internals->viewPropertiesPanel->setPanelMode(
pqPropertiesPanel::VIEW_PROPERTIES);

        this->Internals->displayPropertiesPanel->setPanelMode(pqPropertiesPanel::DISPLAY_PROPERTIES);



It works at start up, but when I use more than one source the display
panel doesn't show any property when switching from one source to
another.

Do you know what can cause this behavior and how to possibly solve it?


Thank you


Federico


P.S. sorry if I sent this mail previously on paraview-developers, but
may be it was the wrong list.

Message-ID: <CAEDQ-RHq6NGJCqwq-250Ru=HWwYio5o0NUH35S7O93ERRfvzjQ@mail.gmail.com>

Hi,

I have 2 files with data which contains x and y components of velocity
field, I try to combine this data into vector and then create particle
tracer, but it doesn't work. Here is the pipeline of the visualisation:
1. data is in NetCDFReader1 and NetCDFReader2.
2. appending: NetCDFReader1, NetCDFReader2 => AppendAttributes1
3. build a vector: AppendAttributes1 => Calculator1 (with the formula
x*iHat + y*jHat + 0*kHat)
4. create seeds source for particle tracer: Line1
5. create tracer: Calculator1, Line1 => ParticleTracer1
6. animating.

but nothing is happening, ParticleTracer1 doesn't display any data, I tried
to replace step 5. with ParticlePath or StreakLine and animate termination
time, but it doesn't work as well.
Note, if I use stream lines in step 5 they are working.

Any advice what may be the reason? Or maybe you know any tutorial for
particle tracing with real example (data, step-by-step instruction).

Thank you,
Mike

Dear all,

I am trying to reuse some code from the point sprites plugin.
I would like to pass some size information onto some shader code for 
nine different points like this:

voidvtkPointSpriteProperty::Render(vtkActor*act,vtkRenderer*ren)

{



vtkPainterPolyDataMapper*mapper=

           vtkPainterPolyDataMapper::SafeDownCast(act->GetMapper());


vtkSmartPointer<vtkDoubleArray>darr=vtkSmartPointer<vtkDoubleArray>::New();

         darr->SetNumberOfTuples(9);

         darr->SetName("testArray");

         double  size_tuple[1]  =  {0.2};

         darr->SetNumberOfComponents(1);


         darr->SetTupleValue(0,  size_tuple);

         darr->SetTupleValue(1,  size_tuple);

         darr->SetTupleValue(2,  size_tuple);

         darr->SetTupleValue(3,  size_tuple);

         darr->SetTupleValue(4,  size_tuple);

         darr->SetTupleValue(5,  size_tuple);

         darr->SetTupleValue(6,  size_tuple);

         darr->SetTupleValue(7,  size_tuple);

         darr->SetTupleValue(8,  size_tuple);



mapper->RemoveVertexAttributeMapping("SizeParam1");
mapper->MapDataArrayToVertexAttribute("SizeParam1",darr->GetName(),

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  0);



glPushAttrib(GL_ALL_ATTRIB_BITS);

glEnable(vtkgl::VERTEX_PROGRAM_POINT_SIZE_ARB);

   this->Superclass::Render(act,ren);
}

shader code :

attribute  float  SizeParam1;

attribute  float  SizeParam2;

attribute  float  SizeParam3;


vec3  GetSizeParams()

{

   vec3  sizeparams=vec3(0.0,0.5,0.8);

     sizeparams.x = SizeParam1;

//   sizeparams.y  =  SizeParam2;
//   sizeparams.z  =  SizeParam3;


   return  sizeparams;

}



Question: How is the 0.2 stored in the tuple modified while passed to 
the shader code ?

Because the value arriving in the
shader code seems to be different from the value 0.2 which is stored in 
the tuples.
I noticed, because if I hardwire 0.2 in the shader code like this


vec3  GetSizeParams()

{

  vec3  sizeparams=vec3(0.2,0.5,0.8);

return sizeparams;
}

I see a different rendering.

Could anyone please cast a light into this issue and tell me what I am 
doing wrong or rather which settings influencing the mapping I should 
draw my attention to ?

Thanks.

Best regards,

Florian

You probably need to glyph the output from the particle path and the
streakline filter to see the locations. Right now I don't think any cells
are being generated by those two filters. If you don't have any points,
you'll probably need to set termination time to something other than 0 for
particle paths. I haven't tested the streakline filter but suspect it has
similar behavior.

Regards,
Andy

Hello,
is there anyone interested to help me to distribute data among nodes?
Reading around to try to solve the problem about my large dataset that I
would like to distribute, I have understood that if I run
mpirun -np 4 pvserver
and I load large csv data file, Paraview redistributes data after
reading it.. 
Is this correct?  
Is there a possibility to change the Process Id Scalar associated to a
value?
Thank you in advance,

Subject: [Paraview] The "configuration" attribute of the "server" tag in
	server.pvsc
Message-ID: <54663DFA.10407@lanl.gov>

Hola Paraviewers,

I'm planning on creating an official "servers.pvsc" file for 
users of our LANL HPC platforms similar to what NERSC 
provides (see 
https://www.nersc.gov/users/software/data-visualization-and-analytics/paraview). 
  I've noticed that if I add a server using the GUI "Connect 
to Server" interface that the resulting saved "servers.pvsc" 
file has the following form of a "server tag" entry:

  <Server name="Whatev" configuration=""
resource="csrc://localhost:11111">
    <ManualStartup/>
</Server>

I'm curious as to what the "configuration" attribute in the 
Server XML tag is used for.  Could it be used to refer to 
another XML "pvsc" file to deal with complication connection 
processes?  Or is it just an unused attribute?

Thanks for your time responding to this inquiry.

Giovanni,

The configuration attribute does seem to be something left over from
the past. It doesn't seem to be used for anything currently.

Subject: [Paraview] make labels from python plugin
Message-ID: <54667BB2.9040500@tul.cz>

Hi,

I have implemented a reader plugin in Python using ProgrammableFilter
and appropriate XML file (http://www.kitware.com/blog/home/post/534)
Thank you, Pat.

However the input contains some text labels attached to particular
points in space. I'm look for way to show them in 3d view. After one day
searching I realized:

1) It probably can not be done within ProgrammableFilter since there is
no source that can produce a text anchored to a 3D point, but always
oriented to the viewer. Am I right?

2) This can be done at client-side, e.g. from Python Shell, using vtk
mappers and actors.

However, I didn't find a way how to create a client-side plugin
implemented in Python. Is it possible? How? If yes, how can I call it
after the server-side of the reader and pass there its data?

I would like to do it in Python because of portability.

I appreciate any hints.

Florian,

MapDataArrayToVertexAttribute expects the data array to be present in
the input data going into the mapper itself. I see you're creating a
new `darr`, but I don't see it being added to a dataset and then that
being passed on to the mapper. Are you doing that?

Having said that, you should look into adding a filter to add this
data array to your dataset, vtkProperty/vtkPointSpriteProperty isn't a
the best place to change input dataset being fed to the mapper.

Yes, you can use `RescaleTransferFunctionToDataRangeOverTime` method
on the "display" object.

> disp.RescaleTransferFunctionToDataRangeOverTime()

Assuming that the scalar coloring was already setup, the above call
will rescale the lut range for the array being used for coloring.

Ability to change filenames depends on specific reader
implementations. I am not entire familiar with the internal
implementation, but if you have a couple of sample datasets/script to
reproduce the segfault, I can check if its a minor fix to the reader
to enable this or if it just can't support it.

Either case, you should be able to call Delete(reader) to delete old
reader once you're done with it to avoid memory bloat.

Subject: [Paraview] Python Programmable Filter: Reading unsigned short TIFFs
	into vtkImageData
Message-ID: <CACZSzUA4C+Ax0wfS87YX75+F6E_jOHTLG+m3kp6SGzxsUmUCjQ@mail.gmail.com>

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

OK, I'm still not yet able to reproduce this bug, but at least I was 
able to write out some state files.

As mentioned before, I only see this happening in a client/server mode, 
i.e. running pvserver on a remote machine.

Three state files are attached, simply visualizing 2D cut-plane data:
1. colorLegBug_OK.pvsm:
    Everything is still working fine and color legend appears as
    expected.
2. colorLegBug_Fail_0.pvsm:
    Switched the color array (from 'Z' to 'SourcePV') -> color legend
    disappears for 'SourcePV', but still is present when switching back
    to 'Z'
3. colorLegBug_Fail_1.pvsm:
    After some more switching of color arrays, the color legend
    disappears for all quantities.

Hope this gives some clues to track down this bug.

Thanks,
Armin

Dear ParaView Users,

I have a vtm 2D data structure, containing:
-> vtp polygons
-> vti image data (field) data


now i want to translate the polygons (for an 'explosion view'), i.e. i 
want to add +1 to all z-coordinates of the polygons.


how can i do that? do i have to code it in the "programmable filter"?


thanks for any suggestion

Simon,

Assuming your 2D datum set is in x,y-coordinates, one can expand this to 
3D by adding a 0.0 value for the "missing" z-coordinate.

PV has a Transform filter that will then let you add a constant value to 
the z-coordinate, or, equally easily, scale the z-coordinate.

On the other hand, if you really want to create a "carpet" plot that 
makes your 2D datum set appear as 'mountains and valleys,' one can 
likewise add the datum attribute (for example, density) as if it were 
the z-coordinate. Again, PV's Transform filter will let you scale the 
z-coordinate into a range that makes the image pleasing. It will be a 3D 
image, that is easily oriented for viewing. The coloring can be either 
by any of the point values, or a single color of your choosing.

There may be a more direct way to achieve this that someone else can 
explain?

Hope this helps.

Sam

Subject: [Paraview] Trying to visualize molecular trajectories from AMBER
	with a binary netCDF file
Message-ID: <DB0D05B8-5298-4324-937C-56B57CD98F0B@gmail.com>

Hi all,
I am trying to visualize the flow of certain molecules in a simulation with 300,000 atoms simulated over 500 time steps. The trajectories were generated in AMBER and output as a binary netCDF file. A text netCDF file could not correctly store such a large data set. 
How can I get paraview read the netCDF that I have and then use it to plot the flow of certain molecules?

Thank you

Thank you, Sam, "Transform" was what i was looking for.

However, consider the following situation:
-> two identical polygons (well, almost identical, in the order of 
machine epsilon)
-> applying the 'Transform' to both of them: moving both by 100 in +z 
direction

Then, strangely, they do not coincide nicely any more. It seems that 
there is some massive inaccuracy introduced by applying the 'Transform 
filter'....

Does anyone have ever encountered that artefact? Any suggestions to 
remove/reduce that?

Best wishes
Simon

Subject: [Paraview] Problem with vtkStringData in Composite dataset
Message-ID: <546CAC7F.9050109@tul.cz>

Dear paraview users,

I have a MultiBlock Dataset
containing a single leaf (vktPolyData) with PointData having a
vtkStringArray named "labels". I try to display these labels selection
the block and setting label format "%s". This approach works if
that leaf block is treated out of the composite dataset, but within
composite dataset I get a warning:

Warning: In
/home/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/Rendering/Label/vtkLabeledDataMapper.cxx,
line 442
vtkLabeledDataMapper (0x597e640): Could not find label array (labels) in
input.

and no labels are shown.

Then I tried to use ExtractBlock + MergeBlocks and apply selection
there, but MergeBlocks simply drops the "labels" array.

Is it an error or should I do something special to make such  an
AbstractArray work.

Below you find a ProgrammableSource script to generate a sample
MultiblockDataset for reproduction of the problem. Here I set "labels"
array to all leaf blocks with the same result.

Thank you for help

This should be fairly straight forward once you have a reader for your 
data. Hence the first questions that comes up:
In which file format is the data stored?

ParaView has a large selection of readers for all kinds of file formats, 
ranging from simple text files (i.e. CSV files) to advanced HPC file 
formats like XDMF. See here:
http://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_readers

I personally prefer writing my data in XDMF/HDF5 files, for which 
ParaView has a very good reader.

For custom, but still simple, file formats also the "Python Programmable 
Filter" might be an option. Google will give you several examples for that.

Message-ID: <CAPMgRLQsDi22aA5mWg7HJDQERr8fKWFEoUmwwM5tnVPya4vMyw@mail.gmail.com>

I'm trying to write an IntVectorProperty with two drop down list next to
each other.

Ideally it would call a function that takes to arguments, and passes the
value of each drop down menu to each argument. I am however open to
workarounds.

This is my best attempt but of course it crashes paraview:

<IntVectorProperty name="Neighbors"
                               command="set_load_node_neighbors"
                               number_of_elements="2"
                               default_values="-1 -2">
    <EnumerationDomain name="enum">
        <Entry value="-1" text="None"/>
        <Entry value="1" text="Faces"/>
        <Entry value="2" text="Edges"/>
        <Entry value="3" text="Corners"/>
        </EnumerationDomain>
     <EnumerationDomain name="enum">
         <Entry value="-2" text="None"/>
         <Entry value="4" text="Same level"/>
         <Entry value="5" text="Children level"/>
         <Entry value="6" text="Both"/>
      </EnumerationDomain>
</IntVectorProperty>

Any ideas / suggestions about how to achieve this?

Bests,
Gonzalo

I try to use paraview for designing some structures and and then I export

The default widget portfolio in ParaView doesn't support such a
property. However, you can implement a custom pqPropertyWidget
subclass that places 2 combo-boxes. Use pqIntVectorPropertyWidget [1]
as a reference. [2],[3] may be useful reads to understand the
property-widget infrastructure in ParaView.

I actually realized that the state files I provided used a rather large
dataset that I didn't provide.

However, I actually have been able to reproduce the bug now consistently
when using an explicit server/client setup.

Here the steps to trigger the disappearance to the color legend:
1) run pvserver (e.g. on the local machine)
2) Connect to pvserver
3) Add a source (e.g. cylinder or sphere)
4) Change the displayed quantities, i.e. the color array, about 5-10
times. Usually I can display each color array at least one time, but
when switching several times between them the legend disappears.

As said, without using an explicit connection to pvserver I cannot
trigger this bug.

I attached again two state files, this time using the cylinder source only.

Thanks for taking care of this!

Hi Utkarsh, dear all,

thanks for your answer. This was just an example (maybe a rather stupid 
one). Please let me rephrase my question:
I am trying to extend the pointSprites plugin with my own shaders. For 
this I would like to pass up to 3 size parameters and the 4 components 
of quarternions for orientation to the shader code. Currently I do it 
like this:

void vtkPointSpriteProperty::Render(vtkActor *act, vtkRenderer *ren)
{
    vtkPainterPolyDataMapper*  mapper  =  vtkPainterPolyDataMapper::SafeDownCast(act->GetMapper());

       if  (mapper)

       {

mapper->RemoveVertexAttributeMapping("SizeParam1");

         mapper->MapDataArrayToVertexAttribute("SizeParam1",  this->SizeParam1ArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);

         mapper->RemoveVertexAttributeMapping("SizeParam2");

         mapper->MapDataArrayToVertexAttribute("SizeParam2",  this->SizeParam2ArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);

         mapper->RemoveVertexAttributeMapping("SizeParam3");

         mapper->MapDataArrayToVertexAttribute("SizeParam3",  this->SizeParam3ArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);

         mapper->RemoveVertexAttributeMapping("rotQionW");

         mapper->MapDataArrayToVertexAttribute("rotQionW",  this->RotQionWArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);

         mapper->RemoveVertexAttributeMapping("rotQionX");

         mapper->MapDataArrayToVertexAttribute("rotQionX",  this->RotQionXArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);

         mapper->RemoveVertexAttributeMapping("rotQionY");

         mapper->MapDataArrayToVertexAttribute("rotQionY",  this->RotQionYArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);

         mapper->RemoveVertexAttributeMapping("rotQionZ");

         mapper->MapDataArrayToVertexAttribute("rotQionZ",  this->RotQionZArrayName,

             vtkDataObject::FIELD_ASSOCIATION_POINTS,  -1);


     
     if  (this->Internal->PushedAttrib  ==  0)
     {
       glPushAttrib(GL_ALL_ATTRIB_BITS);
       this->Internal->PushedAttrib  =  1;
     }
      


       glEnable(vtkgl::VERTEX_PROGRAM_POINT_SIZE_ARB);

         float  sizeParam1Span[2];
         sizeParam1Span[0]  =  this->SizeParam1Range[0];
         sizeParam1Span[1]  =  (this->SizeParam1Range[1]  -  this->SizeParam1Range[0]);
         this->AddShaderVariable("SizeParam1Span",  2,  sizeParam1Span);


         float  sizeParam2Span[2];
         sizeParam2Span[0]  =  this->SizeParam2Range[0];
         sizeParam2Span[1]  =  (this->SizeParam2Range[1]  -  this->SizeParam2Range[0]);
         this->AddShaderVariable("SizeParam2Span",  2,  sizeParam2Span);


         float  sizeParam3Span[2];
         sizeParam3Span[0]  =  this->SizeParam3Range[0]  *  factor;
         sizeParam3Span[1]  =  (this->SizeParam3Range[1]  -  this->SizeParam3Range[0]);
         this->AddShaderVariable("SizeParam3Span",  2,  sizeParam3Span);




         float  rotQionWSpan[2];
         rotQionWSpan[0]  =  this->RotQionWRange[0];
         rotQionWSpan[1]  =  (this->RotQionWRange[1]  -  this->RotQionWRange[0]);
         this->AddShaderVariable("rotQionWSpan",  2,  rotQionWSpan);


         float  rotQionXSpan[2];

in my vertex shader code I have something like this

in float SizeParam3;

uniform  vec2  SizeParam1Span;
uniform  vec2  SizeParam2Span;
uniform  vec2  SizeParam3Span;

     vec3  radius  =  vec3(0.0,  0.0,  0.0);


     radius.x  =  SizeParam1Span.x+SizeParam1*SizeParam1Span.y;
     radius.y  =  SizeParam2Span.x+SizeParam2*SizeParam2Span.y;
     radius.z  =  SizeParam3Span.x+SizeParam3*SizeParam3Span.y;

  ...


  
in  float  rotQionW;
in  float  rotQionX;
in  float  rotQionY;
in  float  rotQionZ;

uniform  vec2  rotQionWSpan;
uniform  vec2  rotQionXSpan;
uniform  vec2  rotQionYSpan;
uniform  vec2  rotQionZSpan;


   vec4  rotQions=vec4(1.0,0.0,0.0,0.0);


   rotQions.w  =  rotQionWSpan.x  +  rotQionW  *  rotQionWSpan.y;
   rotQions.x  =  rotQionXSpan.x  +  rotQionX  *  rotQionXSpan.y;
   rotQions.y  =  rotQionYSpan.x  +  rotQionY  *  rotQionYSpan.y;
   rotQions.z  =  rotQionZSpan.x  +  rotQionZ  *  rotQionZSpan.y;

   ...


I discovered that my the data of the field variable (this->...ArrayName) passed into

MapDataArrayToVertexAttribute(...)

is somehow between 0 and 1. This is why I also have to pass the span to convert it back ( as it is done in the original pointSprite plugin code).


Even though I can render some geometry (for example ellipsoids) around several points/vertices (=this means my shader code works), I have the feeling that the Mapping to the individual vertices is not working as expected !

For example in the case of having three vertices of which each one has different values for SizeParam1, SizeParam2 and SizeParam3 - for example:

v1 : pos(0,0,0) SizeParam1 = 1.0, SizeParam2 = 1.0, SizeParam3 = 1.0
v2 : pos(0,1,0) SizeParam1 = 1.0, SizeParam2 = 2.0, SizeParam3 = 0.5
v3 : pos(0,0,1) SizeParam1 = 1.0, SizeParam2 = 1.0, SizeParam3 = 1.0


where the values for SizeParam1, SizeParam2 and SizeParam3 are taken from the selected fields (=multiblock, where individual blocks represent individual time steps) associated with the points/vertices.


Nevertheless the individual vertices do not seem to receive their correct values !
My current problem is that all of them are rendered the same size, thus I assume that the shader variables are not passed as expected.


The essential difference to the original pointSprites code is that I have several calls to


         mapper->RemoveVertexAttributeMapping(...);

         mapper->MapDataArrayToVertexAttribute(...);

whereas in the original pointSprites implementation there was only 1 call for the RadiusArray.
I checked with the debugger and found that the mappings are added to the array
vtkGenericVertexAttributeMapping* mappings in

void  vtkPainterPolyDataMapper::MapDataArrayToVertexAttribute(
   const  char*  vertexAttributeName,
   const  char*  dataArrayName,
   int  field,
   int  componentno)
{
   vtkGenericVertexAttributeMapping*  mappings  =  0;
   if(  this->PainterInformation->Has(
       vtkPrimitivePainter::DATA_ARRAY_TO_VERTEX_ATTRIBUTE())  )
     {
     mappings  =  vtkGenericVertexAttributeMapping::SafeDownCast(
       this->PainterInformation->Get(
         vtkPolyDataPainter::DATA_ARRAY_TO_VERTEX_ATTRIBUTE()));
     }


   if  (mappings==NULL)
     {
     mappings  =  vtkGenericVertexAttributeMapping::New();
     this->PainterInformation->Set(
       vtkPolyDataPainter::DATA_ARRAY_TO_VERTEX_ATTRIBUTE(),  mappings);
     mappings->Delete();
     }


   mappings->AddMapping(
     vertexAttributeName,  dataArrayName,  field,  componentno);
}



Nevertheless I do not know how to further investigate my problem or where to start looking for the actual mapping and data passing process.
Maybe anybody could point me to the catch here or to the interesting bits of code I should check or maybe explain me about the contraints when passing varying field data to shaders.

Is/Might the fact that I have a multi-block dataset somehow affecting the mapping process ?

Thanks

Best regards,

Florian

Perfect!!

I have replicated this bug, and repeated it a few time.  Breaks every time.  Thanks Armin for writing it up!!  I just targeted PV 4.3, out next month for the fix.

I actually realized that the state files I provided used a rather large dataset that I didn't provide.

However, I actually have been able to reproduce the bug now consistently when using an explicit server/client setup.

Here the steps to trigger the disappearance to the color legend:
1) run pvserver (e.g. on the local machine)
2) Connect to pvserver
3) Add a source (e.g. cylinder or sphere)
4) Change the displayed quantities, i.e. the color array, about 5-10 times. Usually I can display each color array at least one time, but when switching several times between them the legend disappears.

As said, without using an explicit connection to pvserver I cannot trigger this bug.

I attached again two state files, this time using the cylinder source only.

Thanks for taking care of this!

The STL File format can be either ASCII or Binary. ParaView is exporting a binary file. ParaView _may_ offer the option to write out an ASCII file. Looks like Ghex software can only read an ASCII STL file.

Subject: [Paraview] Interfacing with FE simulation using Catalyst
Message-ID: <CADR2tx550NF7O2a4L_PNCJJFfXeZU1Ub0sXPF9yMaVYSzH+4=w@mail.gmail.com>

Hello,

I am trying to use catalyst in our Finite Element framework, but I can't
get it to work right now. For background information, I would like to
inferface a parallel simulation, running with MPI, with paraview to display
the results, thus do live visualization.

I compiled Paraview from the 4.2 sources (from the website) to ensure that
our library compiles with the same library as the ParaView I'm launching.

The problem I have is similar to the one reported in:
http://public.kitware.com/pipermail/paraview/2013-June/028497.html


In our application, we have an exporter interface that allows to write VTK
data (vtkUnstructuredGrid) with field data (scalar, vectorial). I built the
catalyst interoperation on top of it, by using the Cxx example provided in:
https://github.com/Kitware/ParaViewCatalystExampleCode/tree/master/CxxFullExample
<https://github.com/Kitware/ParaViewCatalystExampleCode>
I'm am using a modified version of the feslicescript.py
<https://github.com/Kitware/ParaViewCatalystExampleCode/blob/master/CxxFullExample/SampleScripts/feslicescript.py>
that should enable live visualization IMHO (enclosed with this email).

The excerpt of C++ code running the coprocessing is the following one:
----
vtkSmartPointer<vtkCPDataDescription> dataDescription =
vtkSmartPointer<vtkCPDataDescription>::New();
dataDescription->AddInput("input");

if(inSituProcessor->RequestDataDescription(dataDescription.GetPointer()) !=
0)

  dataDescription->GetInputDescriptionByName("input")->SetGrid(out);
  dataDescription->SetForceOutput(true);

inSituProcessor->CoProcess(dataDescription.GetPointer())<< std::endl;
}
----
where out is the unstructured grid data.

I then launch Paraview and allow connection for catalyst via the menu.
Eventually I launch our simulation that interfaces with Catalyst.

I then get the following error in Paraview:
ERROR: In
/home/ancel/Downloads/ParaView-v4.2.0-source/VTK/Parallel/Core/vtkSocketCommunicator.cxx,
line 812
vtkSocketCommunicator (0x2b1f940): Could not receive tag. 1

And the coprocessing stops in Paraview, altough I can see the catalyst
server in the Pipeline browser and a PVTrivialProducer1 appearing in the
background, but no data appear in the visualization window of Paraview.

I tried instrumenting the code in Paraview to locate where the problem
would be, but it appears that the problem happens outside of the
vtkLiveInsituLink class, which (correct me If I'm wrong) should handle the
link between the application and Paraview.

The different questions that I have would be summed up as:
- Can you give me some pointer as to where the problem might be located ?
Coding mistake on my side ? Did I miss something in the issue I referred to
before ?
- Is it possible to pause the simulation while the user manipulates data in
Paraview ? How ?

Sorry for the long mail, but I tried to be as precise as I could be,
Thanks in advance for the help and your time,

Best regards,
Alexandre Ancel

Hi Alexandre,
The following blog post describes how to pause the simulation and how to
manipulate data in Catalyst Live.

http://www.kitware.com/blog/home/post/722

Could you try the scripts attached in the blog post? Do those work?
Thanks,

You can use the PythonAnnotation filter instead with the following
expression

"{:,}".format(t_value)

Hello Dan,

Thanks for the link to the blog post (I totally missed this one).

I tested the example provided in the blog post, it worked and it made me
understand from where my issue came from. In fact, the simulation was
running and connected to Paraview via catalyst, but I only had one time
step, so as soon as it went throught the Catalyst code, the app continued
its execution and ended before I could visualize data in Paraview.
I then put a user data input before the end of the execution, and now I am
able to see my data in the PVTrivialProducer1 in Paraview.


But an other issue arose then:

When I click on the icon located near the producer to visualize the data, I
get an Extract component added to the pipeline. Trying to visualize this,
then throws me the following errors:

---
ERROR: In
/home/ancel/Downloads/ParaView-v4.2.0-source/VTK/Common/ExecutionModel/vtkDemandDrivenPipeline.cxx,
line 810
vtkPVPostFilterExecutive (0x3efc890): Input for connection index 0 on input
port index 0 for algorithm vtkPVPostFilter(0x3efbe70) is of type
vtkDataObject, but a vtkPolyData is required.

line 504
vtkSMParaViewPipelineControllerWithRendering (0x38bbc00): Data cannot be
shown in the defaulted render view!!
---

Note that when I look in the Information of the TrivialProducer, data is
recognized as Unstructured grid with the correct point, cell and field data
information.
Do I need to provide specific info in the python script ? Like a conversion
to vtkUnstructuredGrid ?


A few more questions come in my mind now:
- If I understand correctly and if the user wants to pause the simulation,
for example when he has only 1 timestep, he would have to do the following
steps:
* Connect with catalyst in Paraview
* Set a breakpoint for time step 0
* launch the simulation
Is that alright ?
Would it be possible to do this with the play/next frame paraview buttons ?

- Looking at the last lines of the blog post concerning pvserver. Is
pvserver catalyst enabled by default ?
Does it mean that I can build the following pipeline ?
Paraview (local computer) <-> pvserver (cluster frontal node) <-> catalyst
enabled simulation (cluster nodes)


Thanks again for your help (it helped me a lot in understanding the whole
process)

Best regards,
Alexandre Ancel

I have not run an example for an unstructured grid. It should work
similarly though.
I recently wrote a Catalyst adapter for an unstructured grid. I will run
Catalyst Live with that to see how that works.

You could try however to save images or entire data from the pipeline
script as it is done in the Catalyst examples.

The communication between catalyst and the simulation happens only at time
steps. Because of that, Catalyst could only stop the simulation at time
step 2.

 You need to enable MPI to be able to run this. pvserver is the paraview
server that does all the rendering, only images are sent to ParaView (GUI).

Hello Alexandre,
Live View runs fine with an unstructured grid. Try to write data out to
disk as it is done in the Catalyst examples as it is a simpler code path.
Does that work?

Hi Alexandre,

If you could reproduce the errors that you're getting in one of the
examples, we could try to track that down. I tried using your script and
didn't have any issues with the CxxFullExample in the Catalyst example code
and PV 4.2.

Anton,

Maybe try adding

stc->getProxy()->UpdateVTKObjects();

after setting the scalar range?

It's always possible there is a bug in the rescaling logic. Do you
have a minimal code example you could post to make it easier to track
down?

Thanks,
Cory

Looks like this may already be fixed too. I could not reproduce it
with  v4.2.0-133-g7e996c8. Alan, can you test with git/master to see
if you can reproduce it as you could with 4.2?

Thanks,

Message-ID: <10475F00-9C0E-42CE-821E-FF00389FE2B1@cynicmansion.ru>

Hello,

I am trying to understand the architecture of paraview and it's dataflow.

1. What kind of rendering happens on client side? What rendering does default paraview client perform? Does it use OpenGL or something? What happens when I drag an image in the client?

2. What kind of data flows between a client, a data server and a rendering server? What's the format?

I tried to search the wiki but either I am a bad lurker or it's not there. I am also not sure which mailing list to use, so I'll send this email to both.

Boris,

In the 3D View, and depending on the Render View settings, the client may
render the geometry (that is the external surface) of the datasets that it
receives from the server using OpenGL, or it can receive and display the
images (remote rendering) generated by the server. With the first mode, the
interaction is performed locally with some VTK graphical pipelines (camera,
interactors, rendere, etc.); when the rendering is performed remotely, the
client sends the local camera properties to the server so it can generate
images from the correct viewpoint.

So depending the mode, the raw surface geometry can be transfered or some
compressed images (different compression techniques are available, see
Settings / Render View panel).

Some other views (eg. 2D plots) may have different behaviour and might
require the full dataset to be transfered from the server to the client for
display/analysis (in this case, this will not scale of course : eg. if you
plot a huge UnstructuredGrid within a Line Plot view after applying the
Plot Data filter)...

Hope it helps,

Joachim

It is out of date ever since since 3.14's redesign of the rendering
architecture so the names of the classes are different but the overall flow
is the same.

Subject: [Paraview] factor in axis label for cube axes
Message-ID: <5473497E.9030902@gmail.com>

Dear all,

How can I change the factor in the axis label? For example, if the 
x-coordinate is from 0 to 2000 (see the attached picture), the axis 
label is "X-Axis (x10^3)", and the values on the axis are from 0.0 to 
2.0. If I change the x-axis label it affects the name only, the factor 
stays the same. I would like to make the coordinates be shown in the 
original scale: 0 to 2000, without the factor in brackets.

Thank you,
Mikhail

Hello,

I tested writing data from the python script, and the data is apparently
written correctly
 when opening the files with Paraview. The issue is only present I try to
extract the data in Paraview.
I'll continue to investigate both in my code and Paraview. If you have
other pieces of advice as to where I could be looking, I would be
interested.

I will also test if I can reproduce the issue with one of the example.

Regards,
Alexandre Ancel

Subject: [Paraview] paraview web issue
Message-ID: <54736AF9.6070008@gmail.com>

Hi All,

Making an attempt to install ParaView web. I need some assistance in 
trouble shooting. I am attaching a set of logs from a single attempt. 
I'm following theinstructions for Ubuntu 14.04 
<http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#%21/guide/ubuntu_14_04>. 
I see the x11 render window open, but the web page shows nothing.

from the error log
[Mon Nov 24 08:48:53 2014] [error] [client 131.243.240.15] File does not 
exist: /var/www/ParaView/www/ws:

from the access log
131.243.240.15 - - [24/Nov/2014:08:48:53 -0800] "GET 
/ws://localhost:9100/ws?sessionId=c3079f24-73f9-11e4-a023-002590202132 
HTTP/1.1" 404 513
131.243.240.15 - - [24/Nov/2014:08:48:53 -0800] "GET 
/proxy?sessionId=c3079f24-73f9-11e4-a023-002590202132 HTTP/1.1" 404 457

Seems that the problem potentially relates to web sockets. How can I get 
further info about what's failing? Can anyone give some hint on 
troubleshooting this issue?

Burlen

Subject: [EXTERNAL] [Paraview] factor in axis label for cube axes

Dear all,

How can I change the factor in the axis label? For example, if the x-coordinate is from 0 to 2000 (see the attached picture), the axis label is "X-Axis (x10^3)", and the values on the axis are from 0.0 to 2.0. If I change the x-axis label it affects the name only, the factor stays the same. I would like to make the coordinates be shown in the original scale: 0 to 2000, without the factor in brackets.

Thank you,
Mikhail

Hi Burlen,

Just to make sure, you are performing the install on an Ubuntu 14.04 ?

Are you trying to try it locally first using "localhost", or are you
targeting a real deploy with a real host name?

Can you share your config file for the launcher + apache?
(You can do it privately depending on your target deploy / security)

Moreover, can you validate that the session id
c3079f24-73f9-11e4-a023-002590202132
 was properly mapped inside the text file that is shared between Apache and
the Python launcher?

Thanks,

Seb

Hi Sebastien,

this is for a public deployment but I am testing in the browser while it 
locally logged into the system. This server is running ubuntu 11.04, 
apache 2.2.22. I hope that this isn't a roadblock.I can't easily upgrade.

your instructions for 14.04 went off OK but in 2 spots I had to find a 
work around:
1) proxy_wstunnel had to be installed manually, this went without a 
hitch and it loaded up without error
2) in the apache config I had to comment #Require all granted as that 
wasn't valid in 2.2

the session id was in the proxy.txt file and had the port number 9100 
which I see elsewhere in the logs, so that looks OK.

I'm attaching the launcher config.

the apache config is pasted below.

Apache 2.2 will probably be an issue as WS forwarding was not properly
supported with url rewrite.

You may need to build Apache yourself on that distribution. The one that
have all the fix and is supposed to work is 2.4.7+.

We have some additional documentation about that part here:

Subject: [Paraview] ParaView 4.1.0 with non-system (conda) python
Message-ID: <CACtu7z382FfwKAmASZiACPFhyeYZHnr8zX-jh24rT+Ru2+Gz2w@mail.gmail.com>

I'm building ParaView 4.1.0 on SL 7.0 (using build script provided with
OpenFOAM-2.3.0). I'd like to use python from my miniconda installation at
/home/username/miniconda. CMake finds this correctly and in CMakeCache.txt
I have:

PARAVIEW_ENABLE_PYTHON:BOOL=ON
PYTHON_EXECUTABLE:FILEPATH=/home/username/miniconda/bin/python
PYTHON_INCLUDE_DIR:PATH=/home/username/miniconda/include/python2.7
PYTHON_LIBRARY:FILEPATH=/home/username/miniconda/lib/libpython2.7.so.1.0
PYTHON_UTIL_LIBRARY:FILEPATH=/usr/lib64/libutil.so

but pvpython and the Python Shell in ParaView use the system python from
/usr/bin/

This is a problem because matplotlib isn't installed for the system python.
I prefer to manage python packages in my miniconda installation.

Subject: [Paraview] Cannot get parallelism working in paraview 4.2.0 on our
 clusters (works with 4.1.0)
Message-ID: <FD60F10D-EB15-457D-B9C0-83C3737F9736@llnl.gov>

Hi,
I have recently compiled paraview 4.2.0 on our clusters in the same way I compile with 4.1.0 and am getting some errors.
I run pvserver in parallel, and it does not give any weird outputs.
I connect with it from my desktop (Mac OS X).  I can see in the desktop GUI that four remote servers are connected.
I open up a PDB dataset and it is different.  I see two ?Output? objects in the pipeline browser.  This is different than the behavior in 4.1.0.

[cid:914AC27C-18D5-42AC-95B6-7668C8B7059B at llnl.gov]

I click Apply and get smacked in the face with an error dialog.

ERROR: In /Users/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release-Python27/paraview/src/paraview/VTK/Domains/Chemistry/vtkBlueObeliskDataParser.cxx, line 68

I?m unable to color by process scalar ID, or more precisely, the Filter seems to get applied but the color does not change.  Appears all work is done on process 0.

Something is vewwwy scwewwy.

Help?

Looks like this may already be fixed too. I could not reproduce it with  v4.2.0-133-g7e996c8. Alan, can you test with git/master to see if you can reproduce it as you could with 4.2?

Thanks,

Hi,

I think I know the cause, the PDB reader was modified to produce a
vtkMolecule in addition to the vtkPolyData I think it has always produced.
It looks like there is a packaging issue, and the XML file cannot be found.
We should probably just statically compile the file in, or convert it to a
header as the data is pretty static - atomic radii, colors, etc.

Subject: [Paraview] Which reader run in parallel?  All of them?
Message-ID: <DB039209-2B16-46CC-B2D5-D220C831ABB3@llnl.gov>

Hello Paraview Overlords,
Does every paraview reader run in parallel with its data?  I know that is not the case with VisIt, so I?m thinking probably not true for paraview either.
If not, is there a list of which readers parallelize and which are not, or a way to compile such a list without reading the source code?
Thanks!

Subject: [Paraview] Which reader run in parallel?  All of them?
Message-ID: <D09A1F7D.1E4EB%kmorel@sandia.gov>

Like VisIt, there exist readers in ParaView that do not perform well or at all when reading data in parallel. There are practical reasons for allowing non-parallel readers to exist within ParaView (and VisIt). The underling architecture is modular and designed to make it straightforward to add components like readers. Thus, the reader implementation often happens outside of ParaView development and is not necessarily designed for parallel usage. It is also the case that many file formats are not very amenable for parallel reading, but there are still good use cases for supporting them in some way in ParaView.

As far as I know, there is no list of what readers do or do not read in parallel. I suppose it would be possible to iterate over all readers and see which ones report pieces or extents, but that would not give reliable information about parallel behavior or the limitations. It would be hard to quantify the parallel behavior of the readers in any meaningful way.

A list of parallel readers may not be the right way to ask the question. A better question to ask is if I have data in a particular format can I read that in parallel? Yes, this is most reliably answered by pouring through the source code, but an email to this list will probably provide a satisfactory answer if its a common format. The converse question is for data of a given type, what is the best file format to use for parallel performance? You're bound to get a more complete answer by asking humans than consulting a list.

Hello Paraview Overlords,
Does every paraview reader run in parallel with its data?  I know that is not the case with VisIt, so I?m thinking probably not true for paraview either.
If not, is there a list of which readers parallelize and which are not, or a way to compile such a list without reading the source code?
Thanks!

Hi, Ken,
your approach makes sense, unless you are in my shoes of maintaining the software for use by others.  In that case, users come to me asking which package they should use to view their data and the ability to view in parallel is an important consideration which I?d like to have at my fingertips.

So far it?s not so frequent, but quantifying it in some way would help me at least as a central maintenance and support guy.  But it seems I will have to take your approach, querying piecemeal as needed.

Thanks
? Rich

Marcus will investigate the errors.

They are not related to why the dataset is no longer distributed. There was
code in 4.1 that automatically redistributed data from serial readers using
a very naive approach. That code is no longer there. We are investigating
various options of improving on the 4.1 functionality. I would normally say
that you can use the D3 filter to distribute the data but I was cautious
and tried it first. It crashes :-( This dataset has string arrays in it,
which it seems D3 does not handle.

Do you have a particular use case driving parallel PDB capability? If you
do, I can find some workarounds of these issues. If not, D3 should nicely
work on most polydata and unstructured grid sources. We are working on
better ways of redistributing the other data types.

Best,
-berk

I do not have an urgent need to view this data.  However, be advised that I got it from what appears to be the PDB canonical source, so I assumed our molecular people would appreciate being able to visualize their stuff. This kind of model doesn?t usually get that big, though, probably.

Thank you kindly.  No workaround is needed.

Hi Sebastien,

OK, I finally upgrade to Ubuntu 14.04 and apache 2.4! however, I still 
have some issue. again I see the render window pop up in the background, 
in the browser I have the ParaView web logo and spinning wheel, now 
after a few seconds a dialog: Session did not start before timeout 
expired. Check session logs.

I cranked up the log verbosity in apache. attached everything. Any idea 
what the problem is? how to get more info? paraview has an error, how 
does that get reported?

Thanks
Burlen

Found the issue! Or at least I think I do ;-)

The short answer is that the "ready_line" property inside your
launcher.json file should be "Starting factory" and not "Starting factory -
XYZ" for all the command lines. (Like written in the documentation ;-)

The reason is that the launcher look for that exact String in the output of
the process that it runs. This allow to know when the process is ready. And
the line "Starting factory - XYZ" never show up, hence the error message
"Session did not start before timeout expired. Check session logs." has it
think the process is not ready.

Let me know if you run into something else.

Seb

BTW, once you update the configuration file, you will need to restart that
launcher process.
It is not smart enough to watch that file. ;-)

And down the road, if you want to use different machine for the Viz, you
can issue some ssh command to remotely start that ParaView process even
with mpi/pvserver.

Subject: [Paraview] csv -> vector variable -> streamline problem
Message-ID: <8B7918BF-FB07-4279-B1E5-650815FD3547@exmail.nottingham.ac.uk>

Hi,

I have a csv file that is a 16x16x16 of data in the form: 

x, y, z, rho, j_x, j_y, j_z

I am using a pipeline of:

csv Reader  |  Table To Points (x, as X Column? etc.)   |  Calculator (iHat* j_x+jHat* j_y+kHat* j_z)   >    Result

Looking at Result in the spreadsheet view shows a vector variable as I would expect. Also, visualising the result of the calculator filter as 3D Glyphs displays an expected grid of arrows, but they are all oriented pointing along the X axis. When I colour this by the Magnitude of Result they are coloured as expected, with the expected areas of high magnitude being red etc. 

I suspect I have already run into problems at this point, but if I continue and add a Stream Tracer to Result I see nothing. There are no streamlines shown.

I have been trying to work out the problem, and been searching around for any clues. Any help on pointing out where I have gone wrong is greatly appreciated.

I have attached the example csv.

Many thanks,
James

Hello,

An update on this issue that I'm still having:
I tried to pinpoint the source of the problem. I went through Paraview and
VTK code, and found that there is a check that fails to pass apparently,
resulting in the errors previously mentionned. This check fails on the
Paraview side.
In VTK/Common/ExecutionModel/vtkDemandDrivenPipeline.cxx (from which
vtkPVPostFilterExecutive inherits), the InputTypeIsValid (l.763) function
seems to check for data type, and fails to find a matching type when I try
to visualize the data extracted from the PVTrivialProducer.
The recorded type (with input->GetClassName()) is vtkDataObject and the IsA
function is unable to match it with any of the type in the list iterated
over.

Did I went to far in the code ? Could the information about the
Unstructured grid nature be lost when I extract the data in Paraview ?

By the way, this list is probably not the right place to talk about it,
since it is related to VTK, but isn't the error printed when no match is
found a bit confusing for the user ?
I mean if the function does not find a valid type, it will by default
choose the first type of the list, resulting in the kind of errors I had
(vtkPolyData in my case):
vtkPVPostFilterExecutive (0x3efc890): Input for connection index 0 on input
port index 0 for algorithm vtkPVPostFilter(0x3efbe70) is of type
vtkDataObject, but a vtkPolyData is required.

Whereas the type checked was not matched with any type, thus not a
vtkPolyData.

By the way, if you want to have a look at the C++ code used in our library,
it is available in:
https://github.com/feelpp/feelpp/blob/develop/feel/feelfilters/exporterVTK_impl.hpp
With:
- the initialization part starting at line 115
- the coprocessing part starting at line 406

Thanks again for the help,
Best regards,
Alexandre Ancel

Hi James,

You need to create volumetric cells for 3D. You can use the Delauney3D
filter to do that or use the Table to Structured Grid filter if your points
are ordered properly from in the CSV file. Then the stream tracer filter
will work fine.

Regards,
Andy

Hi,

My guess is that the templating isn't working the way you think it is. I
couldn't see where vtkout_type was being set but in general you probably
don't want to template on the VTK data sets since the API where the work is
done is different for each of them. Also, input->GetClassName() should be
returning the name of the actual class you want to use, e.g. vtkPolyData,
vtkUnstructuredGrid, etc.

Another thing I noticed is that you probably want to get rid of the
SetForceOutput(true) in:
if(inSituProcessor->RequestDataDescription(dataDescription.GetPointer()) !=
0)  {  dataDescription->GetInputDescriptionByName("input")->SetGrid(out);
dataDescription->SetForceOutput(true);  std::cout << "CoProcess " <<
inSituProcessor->CoProcess(dataDescription.GetPointer())<< std::endl;  }
This will ensure that all output from Catalyst is generated when possibly
only a single output was requested in the pipelines.

Regards,
Andy

Nightly builds are not available on the Kitware website.  I have a user that needs to try a nightly.  Is there an ETA on when it will be fixed?

Thanks,

Thanks Rich. The molecule data gets into the range that requires parallel
visualization extremely rarely. However, this may affect others, such as
those loading large vtu files. We'll make sure that this is fixed very soon.

They are not related to why the dataset is no longer distributed. There was code in 4.1 that automatically redistributed data from serial readers using a very naive approach. That code is no longer there. We are investigating various options of improving on the 4.1 functionality. I would normally say that you can use the D3 filter to distribute the data but I was cautious and tried it first. It crashes :-( This dataset has string arrays in it, which it seems D3 does not handle.

Do you have a particular use case driving parallel PDB capability? If you do, I can find some workarounds of these issues. If not, D3 should nicely work on most polydata and unstructured grid sources. We are working on better ways of redistributing the other data types.

I have recently compiled paraview 4.2.0 on our clusters in the same way I compile with 4.1.0 and am getting some errors.
I run pvserver in parallel, and it does not give any weird outputs.
I connect with it from my desktop (Mac OS X).  I can see in the desktop GUI that four remote servers are connected.
I open up a PDB dataset and it is different.  I see two ?Output? objects in the pipeline browser.  This is different than the behavior in 4.1.0.

Subject: [Paraview] OpenFOAM Reader - Showing multiple velocity components
	simulaneously
Message-ID: <CAN5F63HfnTmmohEo_7R2WQBteFryTTMeWYrMYt72HOKaJW-4=w@mail.gmail.com>

Dear ParaView list,

I'm currently trying to open multiple 'RenderView' windows so that I
can show, for example, U_x, U_y, and U_z along with U_Magnitude
simultaneously for the purpose of exporting an animation using
ParaView-v4.2.0.

Studying a Python trace whilst switching components using the Qt GUI
suggests this is not trivially possible using either the GUI or a
Python shell.

The Python trace shows these lines:
   uLUT = GetColorTransferFunction('U')
   uLUT.VectorMode = 'Magnitude'
and switching to, for example, U_y requires
   uLUT.VectorMode = 'Component'
   uLUT.VectorComponent = 0

Since the uLUT proxy is returned by the GetColorTransferFunction('U')
function, I'm unsure but doubting that I can duplicate this proxy and
set different values in different Views.

Duplicating data files allows the reading of a file multiple times,
but isn't really practicable given memory constraints etc.

Looking at the OpenFOAM reader in vtkOpenFOAMReader.{h,cxx} and
vtkPOpenFOAMReader.{h,cxx} suggests that the relevant function to
modify in the reader might be

    vtkFloatArray *vtkOpenFOAMReaderPrivate::FillField(vtkFoamEntry
*entryPtr, int nElements, vtkFoamIOobject *ioPtr, const vtkStdString
&fieldType)
.P
but since this has to return a (single) vtkFloatArray*, I'm unsure if
any modifications are likely to help me.

The 'U' field can be identified using statements like:
    if (ioPtr->GetObjectName() == "U") { // process here }
Individual components are accessible using:

    data = static_cast<vtkFloatArray *>(entry.Ptr());
    float *tuple = data->GetPointer(nComponents * tupleI);
    tuple[0] = xValueOfVelocityForCellReferedToByTupleI;

etc.

The function can be found around line 6480 in vtkOpenFOAMReader.cxx

Does anyone have an idea I could use to simultaneously display
different velocity components (and magnitude, if possible, but this
can be coded into a 4th component fairly easily I suspect, if only
individual components could be simultaneously shown)?

Best,

Christian Butcher

Hello,

Regarding to the vtkout_type, it is defined in the corresponding header:
https://github.com/feelpp/feelpp/blob/develop/feel/feelfilters/exporterVTK.hpp
I guess it is not really an issue as it is a typedef to
vtkUnstructuredGrid. Initially I intended to use vtkPolyData for 1D and 2D
meshes; and vtkUnstructuredGrid for 3D meshes, but I guess that I will
totally switch to vtkUnstucturedGrid as it would be able to handle all the
cases.

Thanks for the advice regarding to ForceOutput, I'll change it.

Now back to my issue, I managed to make it work. In the end, it was only me
misusing Catalyst.
Just how I make it work now: (for people that might have a similar issue to
mine)
- Launch Paraview and allow connections for Catalyst
- Pause the simulation (It will thus pause at the first timestep)
- Launch the simulation and visualize the data in Paraview

Thanks again for your time and help,

Best regards,
Alexandre Ancel

Dear all,

the vortex detection(vortex core line) and visualization has been popular,
but this function does not exitst in paraview.

when dose paraview support this function ?

thanks.

Subject: [Paraview] Bugs with pvti and pvd
Message-ID: <82889283-897A-4AF7-86AE-05870691B50C@tacc.utexas.edu>

Hey y'all -

Tracking down a user's problem, I'm getting some problems with parallel-format files.    I've generated a little test case using the Wavelet source and a Calculator, creating three time steps with Result being mag(coords)*1.0 1.1 and 1.2, which contour as a shrinking sphere.   I'm running it on 4 processes, so when I export each "timestep" I generate 4 .vti's and a .pvti.    These are the 'w' files.

When I try to load the following  w.pvd on Maverick (1 node, 4 processes):

<?xml version="1.0"?>
<VTKFile type="Collection" version="0.1" byte_order="LittleEndian">
<Collection>
<DataSet timestep="0" group="" part="0" file="w-0.pvti"/>
<DataSet timestep="1" group="" part="0" file="w-1.pvti"/>
<DataSet timestep="2" group="" part="0" file="w-2.pvti"/>
</Collection>
</VTKFile>

(as per http://www.paraview.org/Wiki/ParaView/Data_formats#PVD_File_Format) I get only parts of the data for each timestep when I use 4.2, and when I use 4.1 I get a double-ghost-zone gap between the partitions.

When I write a similar dataset after Tetrahedralizing it (to get the vtu files my user is having troubles with), 4.2 does the same thing - only shows one partition, though 4.1 seems OK.  These are the the 't' files.

I've uploaded the dataset to:   https://utexas.box.com/s/iwn4ajbvfh2davd375gh

Subject: [Paraview] Extents problem
Message-ID: <2B384706-86E3-44FA-91D8-10FAF834FB23@tacc.utexas.edu>

Hey y'all -

I'm trying to write a parallel reader for a user's structured grid and am having a problem with extents.    I've included a plugin that demonstrates the problem - a little "importer" that hardwires a whole extent of 0,10 in each axis.  In RequestInformation it calls:

  outInfo->Set(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),this->Internals->extent,6);
  outInfo->Set(CAN_PRODUCE_SUB_EXTENT(), 1);

and in RequestData it calls

  outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_EXTENT(),subext);
  vtkStructuredGrid *sgrid = vtkStructuredGrid::SafeDownCast(output);
  sgrid->SetExtent(subext);

to get the update extent from the pipeline and set it onto the structured grid..  It then stuffs points and data to create a grid from -1 to 1 in each axis.

When I run it on 2 processes, the result *looks* right, it fills the -1 to 1 space along each axis, there are the right number of cells and points, ProcessIdScalars shows two equal size partitions, but the extent is clearly not right - the wireframe and surface surface boundaries are incomplete and the extent shown in the Information tab is correct for only one of the two parts.

So, what am I doing wrong?

If anyone is interested, I uploaded the plugin code to:      https://utexas.box.com/s/d6ef5kx4oxm1d205hbbo

Subject: [Paraview] XDMF Bug (Hard-coded drive letter C:)
Message-ID: <2911E772881F8B4AB39462AA4A35EC550101989D8A@NL0230MBX12N1.DIR.slb.com>

It appears ParaView uses the wrong drive letter when writing or reading HDF5 files via XDMF.

Steps to reproduce:
Start ParaView (I am using Version 4.2.0 64 Bit for Windows 7 64-bit)
>From the menu, select  Sources --> Plane
Set X Resolution 10
Set Y Resolution 10
Apply
File --> Save Data
  File format Xdmf data file
  File name D:\SAMPLE.XMF

Open the XMF file in a text editor.
Bug 1: The file refers to D:/SAMPLE.h5 .   However, there is no such file.  The HDF5 file is C:\SAMPLE.H5.

Bug 2: Reset the ParaView session and open the file D:\SAMPLE.XMF.  Apply. The data loads properly, although the XMF file refers to D:/SAMPLE.h5, which does not exist.

Bug 2.1: Reset the ParaView session. Move the file SAMPLE.H5 to D:\  (The directory referenced in D:\SAMPLE.XMF) In Paraview, select File --> Open SAMPLE.XMF.  Apply.

The program displays the Output Messages window with the following error message:
ERROR: In C:\DBD\pvs-x64\paraview\src\paraview\VTK\IO\Xdmf2\vtkXdmfReader.cxx, line 409

There seems to be a glitch in the component that uploads the binaries

can still download the binaries form the dashboard itself [1].
