Re: [Paraview] undefined symbol: PyUnicodeUCS2_AsEncodedString

[Shawn Waldon]

Hi Fabian,

It looks to me like you built against a Python that was configured with
UCS2 unicode objects and are linking to a Python that was configured with
UCS4 unicode objects.  Python is not ABI-compatible with other Pythons that
were built with a different kind of unicode support.

Re: [Paraview] Exodus multiblock dataset block numbers vs block

[Shawn Waldon]

Hi Dennis,

I can answer part of your question.  The block number is the index in a
pre-order traversal of the tree of blocks in the dataset.  The root is
element 0, its first child is 1, that block's first child (or if none, the
root's second child) is 2 and so on.  Your blocks with data are likely two
levels down since your index has that offset (and your code backs this up
since you are asking for the metadata of a child of the root's block 0).

HTH,
Shawn

Re: [Paraview] Overlapping ParaView windows obscuring each other in ParaViewWeb visualizer server

[Shawn Waldon]

Hi Louise,

I have seen something like this before when using VTK render windows on
Linux with NVidia drivers.  There is a bug/feature in the NVidia driver
where it only renders the part of the window that is shown onscreen.  The
workaround I used at the time was to enable offscreen rendering (which I
think ParaView will do by default in the 5.5 when that is released in a few
months).  In ParaView master/5.5 it will be a command line option too
--force-offscreen-rendering, but I think for 5.4 and earlier you would need
to build ParaView with offscreen rendering enabled and then use that
ParaView for Visualizer.

HTH,
Shawn

Re: [Paraview] Unable to build paraview in ubuntu

Hi Jose,

Please keep the list in the conversation so that others can chime in too
(and/or find the solution in the future).  I'm not sure why pvpython is
even linking to Qt.  As far as I know it shouldn't be.  If you want to

Re: [Paraview] Unable to build paraview in ubuntu

Hi Jose,

The real error is higher up in your build log, that is just make's output
that something failed.  It looks like the pvpython executable failed to
link, so you need to scroll back and look for the link error.

Re: [Paraview] Python Scripting

[Shawn Waldon]

Hi Richard,

Since you didn't specify the version you are using I'm using 5.4-RC3 for
this answer.  I loaded a dataset and ran the Python Trace (Tools -> Start
Trace) to find out what it is doing.  Here is the python script that was
generated from changing what the dataset was colored by.


# get active source.

canex2 = GetActiveSource()


# get active view

renderView1 = GetActiveViewOrCreate('RenderView')

# uncomment following to set a specific view size

# renderView1.ViewSize = [1330, 670]


# get display properties

canex2Display = GetDisplayProperties(canex2, view=renderView1)


# set scalar coloring

ColorBy(canex2Display, ('POINTS', 'VEL', 'Magnitude'))


# get color transfer function/color map for 'vtkBlockColors'

vtkBlockColorsLUT = GetColorTransferFunction('vtkBlockColors')


# Hide the scalar bar for this color map if no visible data is colored by it.

HideScalarBarIfNotNeeded(vtkBlockColorsLUT, renderView1)


# rescale color and/or opacity maps used to include current data range

canex2Display.RescaleTransferFunctionToDataRange(True, False)


# show color bar/color legend

canex2Display.SetScalarBarVisibility(renderView1, True)


# get color transfer function/color map for 'VEL'

vELLUT = GetColorTransferFunction('VEL')


It is hiding the scalar bar for vtkBlockColors since that is what the data
used to be colored by.  I think your problem will be solved by using the
GetDisplayProperties and ColorBy functions rather than setting
ColorArrayName.

HTH,
Shawn

Re: [Paraview] Problem with exporting spreadsheet view

[Shawn Waldon]

John,

I just tried the 5.2.0 binaries on Windows 7 and I didn't see this issue,
so it may be some idiosyncrasy of Windows 10 or I'm not following the right
steps to reproduce it.  I'll try to track down a Windows 10 machine
tomorrow, but if you could give me a step-by-step list of how to reproduce
this it would help.  So far I have:

Loaded your state file
export spreadsheet
scroll down to the 1023rd/1024th line -> it is fine


Loaded your state file
scroll down to the 1023rd/1024th line
export spreadsheet -> again it is fine

If I click around on the spreadsheet I sometimes get "..." replacing the
entries above or below the 1023/1024 line as it reloads the data for those
items, but I never see garbage data.

Shawn

Re: [Paraview] ruler filter in paraview-git

[Shawn Waldon]

Hi Mark,

So the confusion is that there are now two rulers in ParaView.  The one
under the filters menu is the one you are seeing.  It was added so that the
user could measure the dataset in each dimension (and possibly it could be
extended to selecting other measurements).  The older behavior is the Ruler
under the Sources menu (it doesn't take an input dataset, but you can
freely set its end points).  The fact that they are named the same means
that the Ctrl-Space search favors the one in the filters menu.  Perhaps we
could change the name of one of them to make it more clear?

HTH,
Shawn

Re: [Paraview] ParaView and Qt 5

[Shawn Waldon]

Hi Mark,

CMake uses different variables to find Qt4 vs Qt5.  QT_QMAKE_EXECUTABLE is
the Qt4 variable and is ignored by the code to find Qt5.  The variable you
want is: -DQt5_DIR=/software/path/qt-5.7.1/lib/cmake/Qt5

No, that another issue and was done intentionally.  When running ParaView
in client-server mode with multiple MPI server processes, it is possible
the input polyline could be spread across the servers.  So it gathers them
from all the processes and merges all the polylines into one long line
before executing the filter.  I don't think there is a good way (other than
running multiple Slice Along Polyline filters) to get two separate regions
to work.  Also, the math for the implicit function you have to write gets
more complicated with two regions.  The current vtkPolyPlane won't handle
it.

Re: [Paraview] Project polygon onto surface

[Shawn Waldon]

Hi Adam,

The Slice Along PolyLine filter looks for a vtkPolyLine type cell.  But
there is no reason the algorithm itself can't work with a polygon (the
current implementation just doesn't look for one and may not handle it the
way you want if you pass a polyline that happens to have a first and last
point that are the same).  You would have to modify vtkPolyPlane to handle
a polygon input rather than assuming the first and last segments go off to
infinity (add an option for this).

If you want to color the inside, you have to get into how the algorithm
works a bit.  Internally I am using a vtkImplicitFunciton (vtkPolyPlane) to
compute the distance of each point in the dataset (or its projection into
the plane of the polyline) from the polyline.  Then I run a Contour filter
(vtkCutter), contouring where that filter's value is 0 and the output is
the slice along the polyline.  But if you directly applied the vtkPolyPlane
implicit function to your dataset and appended that as a data array rather
than contouring by it and throwing it away, you could get colors for
distance from the line.  You could then use the Calculator filter to scale
and color this however you wanted since the distance will be negative for
one side of the line.

HTH,
Shawn

Re: [Paraview] How to merge .vtk files to visualize the result in Paraview

[Shawn Waldon]

Hi Brennen,

ParaView has support for loading multiple files as a time series if you
name them file1.vtk, file2.vtk, etc.  We realize that sometimes these
multiple files are multiple blocks of output rather than multiple timesteps
so I recently implemented a filter that converts the time series into a
multiblock dataset by putting each time step into a block in the dataset.
You can use this with the existing reader to convert the time series that
ParaView thinks your data is into a multiblock dataset with all of the data
in it.  The new filter is called 'Group Time Steps' and is available in
master or the 5.2 release candidates.

HTH,
Shawn

Re: [Paraview] Compute line between coordinates

[Shawn Waldon]

Hi Dorian,

Try applying the clip to the original data before you apply the glyphs.
That should do what you want.  The data will be clipped and then the glyphs
will be applied later and not restricted by the bounds of the clip.

Shawn

Re: [Paraview] ParaView 5.2 Release Candidate 2 available for download

[Shawn Waldon]

Hi Fabian,

CMAKE_OSX_SDK needs to be something like `macosx10.9`.  I forget the
command to make XCode list the valid sdk versions available.  For your case
I would guess `macosx10.12` is the correct value.  Qt looks up the path to
the SDK from that string.

Re: [Paraview] Feasibility of and documentation on implementing a Paraview Client.

[Shawn Waldon]

Hi Magnus,

I don't know much about getting ParaView to work in the client-server mode
you describe and less about the Unreal engine, but if you are willing to
sacrifice a little bit of rendering speed would be to build VTK with OSMesa
and let it do software rendering rather than requiring a hardware context
(which it can't seem to get due to some interference with Unreal).  I just
thought I would point out the option, you can try it and decide if you
think the rendering speed hit is too much.

HTH,
Shawn

Re: [Paraview] Paraview with osmesa cmake issue

[Shawn Waldon]

Hi Chris,

What are you passing in for $*?  CMake, when run in a directory without a
CMakeCache file interprets the current directory as the build directory and
its last (non -ed) argument as the source directory.

HTH,
Shawn

Re: [Paraview] [Non-DoD Source] Re: Qt version support update 2016

[Shawn Waldon]

Mega Mind,

I have a project that is using ParaView with Qt 5.7 on Windows.  Of course
we use VS 2013 still, so that may be the difference.  It still sounds like
you forgot to set the PARAVIEW_QT_VERSION to 5.  If this is 4 (the
default), the CMake scripts will ignore Qt5.  I think it may be smart
enough to default to 5 when there is no Qt4 preset which may be why that
build worked.  Our build machine has both Qt4 and Qt5 installed and it
works fine.  Still, I don't know if anyone has tried Qt5 + VS 2015
Anyway, your runtime error with the dll not found?  That is a Windows
thing.  Not found means it is not in the PATH environment variable's list
of folders.  Windows doesn't bake into the executable the paths to its
runtime dependencies.  Linux and OSX do, which is why you can typically run
things from a build tree there without any problems.  But to run it from
Windows, you will need to add the Qt5 dll's directory to your PATH or move
it to the same directory as the executable which needs it.

Simon,

The ParaView Superbuild uses a precompiled python 2.7 that was built with
VS 2008.  Python 2.x doesn't support any newer versions (maybe 2010, but
we've never used that version of python).  Since the API we link against is
pure C, there are no ABI issues with using this prebuilt version.  You
should be able to look in the superbuild and find the path for the zip file
with the prebuilt python and download/use that one.  I know Python 3 is
supported in VTK, but I'm not sure it is fully supported in ParaView yet.

HTH,
Shawn

Re: [Paraview] Qt version support update 2016

[Shawn Waldon]

To use Qt5, you have to set the PARAVIEW_QT_VERSION variable to 5 (it still
defaults to 4, which is why cmake is complaining).  Note that some things
may be buggy when building against Qt5, I don't know the full list of
current issues, just that there are some.  Also note that you have to
specify the location of Qt5 differently to CMake.  CMake doesn't use the
QT_QMAKE_EXECUTABLE variable for Qt5, instead it uses Qt5_DIR.  This should
point to .../lib/cmake/Qt5 inside your Qt5 install.

Re: [Paraview] Procedure for compiling Catalyst

[Shawn Waldon]

He doesn't need to delete and re-clone.  The recursive flag just does a
normal clone followed by a git submodule update --init.  So run that
command in your paraview source tree and you should be fine.

Re: [Paraview] (no subject)

[Shawn Waldon]

Hi Vince,

This is expected.  Essentially ParaViewWeb allows you to remotely view the
ParaView output with your browser.  If you launched the Visualizer without
pointing a browser at it and then went to another computer and pointed a
browser at the first computer, you would see the ParaViewWeb output.  The
window would still pop up on the computer running ParaViewWeb.  Essentially
the problem is that ParaView needs an OpenGL context to do its rendering
and on most operating systems this requires a window.  So it creates a
window to get the OpenGL context and uses onscreen OpenGL.

You can change it to use offscreen rendering by finding where it creates
its render view and setting view.UseOffscreenRendering = 1.  But you still
get a window that pops up (it is just a blank window now).  I'll let you
know if I figure out how to get rid of the window altogether.

Re: [Paraview] Paraview compile download timeout

[Shawn Waldon]

Which version of CMake are you running?  We have had problems in the past
when using a CMake not built with SSL support pulling new data from midas.
The error messages from that generally look like this:


CMake Error at /apps/pkg/paraview-5.0/src/paraview-5.0/CMake/ExternalData.
cmake:749 (message):
  Object MD5=6c0dd882aa361431b95d7e2feb87fece not found at:


http://midas3.kitware.com/midas/api/rest?method=midas.bitstream.download=6c0dd882aa361431b95d7e2feb87fece=MD5
("Unsupported protocol")

http://www.paraview.org/files/ExternalData/MD5/6c0dd882aa361431b95d7e2feb87fece
("HTTP response code said error")
Call Stack (most recent call first):
  /apps/pkg/paraview-5.0/src/paraview-5.0/CMake/ExternalData.cmake:771
(_ExternalData_download_object)

If this is the problem you will need to download a new CMake that is built
with SSL support or build one yourself.

Re: [Paraview] Scipy installation9814651912

[Shawn Waldon]

You would need to either build scipy against ParaView's python or build
ParaView against system python and install scipy in that system python.
Otherwise you are likely to get strange behaviors if the python versions
don't match.  I would recommend building ParaView against the system python
since Scipy's build system is difficult.

Re: [Paraview] OpenGL Backend Identification

[Shawn Waldon]

There *is* a global VTK configuration header.  vtkConfigure.h has many of
these definitions and is included in vtkObjectBase.h (so pretty much
everywhere).  But you may be right that this should go somewhere in the
rendering code rather than in there.  I am not sure that vtkRenderWindow is
the best location for it, but I am not as familiar with the code that uses
the compiler definition.  Does everywhere that #ifdefs VTK_OPENGL2 include
vtkRenderWindow.h?  Or would we have to pull in that header just for that
macro?

Re: [Paraview] Possible bug in recent SuperBuild?

[Shawn Waldon]

Hi Giovanni,

kwgitlab is the kitware-internal instance of gitlab.  We were hosting the
genericio project there while it was not open sourced.  The base code has
now been open sourced by ANL at the address Utkarsh linked to, but I
haven't had time to get the changes that kitware has made to the library
upstreamed to the version hosted at ANL yet.  Unfortunately ParaView needs
these changes.  It is on my todo list...

Re: [Paraview] [EXT] Re: Exodus Block Names

[Shawn Waldon]

Dennis,

Given those block names, I think I know what you are missing.  It is
possible for a block to be a vtkMultiBlockDataSet itself, in which case you
would need to get the block with mbi.GetBlock(0) and then do another loop
over the blocks in that one to look at the block names.  A quick way to
check this is to look at the Information panel in ParaView.  The tree there
reflects the tree in the data and each node you can expand is a
vtkMultiBlockDataSet (or other composite dataset type, but that one is the
most common).

Re: [Paraview] [EXT] Re: Exodus Block Names

[Shawn Waldon]

Hi Dennis,

The metadata is on the reader's output, which is a vtkMultiBlockDataSet.
reader.GetOutput() should get you the dataset in your python script.
Inside the programmable filter you will need to get the input dataset
(self.GetInput() should get you the input dataset and self.GetOutput()
should get you the output dataset).  So something like the following for
your programmable filter:

mbi = self.GetInput()
mbo = self.GetOutput()

mbo.ShallowCopy(mbi)

for i in range(mbo.GetNumberOfBlocks()):
  metadata = mbo.GetMetaData(i)
  name = metadata.Get(vtk.vtkCompositeDataSet.NAME())
  # do something with the name

Re: [Paraview] Exodus Block Names

[Shawn Waldon]

Hi Dennis,

The block name is in the block metadata, which is not where I looked the
first time either.  Here is a code snippet that shows how to access it.

mb = vtk.vtkMultiBlockDataSet()
...
for i in range(mb.GetNumberOfBlocks):
  metadata = mb.GetMetaData(i)
  name = metadata.Get(vtk.vtkCompositeDataSet.NAME())

HTH,
Shawn

 All,



 Once again, I need help.  We are starting to assign names to our Exodus
 blocks (outside of Paraview).   This is very useful for ease and clarity of
 post processing and allows convenient reference to actual components.   The
 good news is that Paraview seems perfectly happy to read in the Block Names
 and use them in the Properties Panel and the Multi-block Inspector and the
 Find Data screen if they exist (no action or programming required for
 this).  So, for instance, instead of Paraview generating the non-useful
 name of “Unnamed block ID: 13 Type: hex” when the blockname is empty, it
 will automagically use the more useful Blockname of “Tread”  if that is in
 the Exodus file.



 However, there has been an unintended consequence of this change.   If I
 select some elements and examine them in Spreadsheet View, I see Block
 Number 14( the +1 offset from Block_ID and Block Number is NOT the
 problem!).   And now I can no longer associate the element (Block Number
 14) with it’s block in the Properties Panel or the Multi-block Inspector or
 the Find Data panel – where the same block is called “Tread”.



 So, to remedy this situation I would like to add an element variable of
 BlockName, which would contain “Tread” for all the elements in BlockID 13,
 etc., etc. for all the blocks.



 My only problem is I can’t seem to find the list of Block Names.   I’m
 pretty weak at vtk, so it must be available but I surrender – I can’t seem
 to find it.   If someone can help me find the list of Block Names from
 inside the Programmable Filter, I’ll be happy to add the element variable
 myself.



 Thanks for any help, again!



 Dennis

Re: [Paraview] Integrate globe view into custom application

[Shawn Waldon]

Hi Tobias,

I'll let others answer your first few questions since they have more
experience there.  But I can answer your question about updating based on
camera position.

On Mon, Aug 17, 2015 at 11:58 AM, Tobias Beeh tobias.b...@t-online.de
wrote:

 Hello,


 our team (11 students from the university of Stuttgart) is trying to
 build a geovisualization environment on top of paraview.
 Right now we're planning the architecture, which is quite difficult as
 no one of us has any previous experience with paraview.

 We discovered the class vtkGeoView and wondered if we could integrate
 this view into the paraview UI.
 If possible we would like to combine this view with other data loaded
 into the paraview pipeline.
 Otherwise we would need to re-write the whole vtkGeoView with LoD and
 dynamic loading because the whole globe hi-res texture is probably too
 big to load it into the RAM at once - even if not some other large data
 sets need to fit in there as well.
 We would like to avoid this of course.


 Another approach we discussed was to tile the globe for different zoom
 levels and load only those currently displayed, but we could not find an
 automated way to reload geometry based on the camera position.


To do this you'll want to use the mutliresolution streaming support.  There
are some details here:
http://www.paraview.org/ParaView/index.php/Multi-Resolution_Rendering_with_Overlapping_AMR
The best example code is probably in the Streaming Particles plugin.  This
can be found in the ParaView source tree under Plugins/StreamingParticles.
There should be an example data source that produces streamable data as
well as the ParaView representation to support streaming.  You'll probably
have to customize your own versions of both since these were designed to
work with sets of points rather than geometry.

HTH,
--Shawn



 Pointers to useful development resources (other than the official
 paraview guide, documentation, wiki and examples) are appreciated as well.
 Thank you for your time,

 Tobias Beeh

Re: [Paraview] how to build 4.3.1 with CosmoTools

[Shawn Waldon]

CosmoTools is part of a closed-source project at ANL.  The
COSMOTOOLS_INCLUDE_DIR is incorrect and you need to provide the
COSMOTOOLS_LIBRARIES variable with the external library to link against.
The small part of it that the ParaView module depends on was added to
ParaView so that we wouldn't have the closed-source dependency.
Unfortunately, that change didn't make it into 4.3.1, but if you build
against ParaView's master branch, you will no longer need the closed source
cosmotools package and will still have most of the features in the
CosmoTools module.

HTH,
Shawn

Re: [Paraview] vtkDoubleArray with 3 components

[Shawn Waldon]

Hi Bruce,

SetNumberOfTuples reallocates the internal datastructure of the data array
to be the new required size based on the new number of components and
number of tuples.  This (combined with trying to clean up the old data from
SetArray) may be causing the heap corruption you are seeing.  Try setting
the number of components and number of tuples before adding the data to the
array.

HTH,
Shawn

 Hi Cory,

 Sorry for the delayed response, I've hit another more serious bug which
 has been diverting my attention from this.

 Thanks for the state file, I haven't got it to work as I don't have numpy
 set up, but I have also got this working with 9 component arrays in
 paraview using a python script. However, I am now trying to port my python
 plugin to c++ which is where I am seeing the error.

 In my plugin I want to output a vtkarray for each vtkarray in the input
 dataset. The values in the output vtkarrays are interpolated from those in
 the input vtkarrays. Rather than working directly on vtkarray objects, I am
 allocating c++ arrays for each vtkarray, performing the interpolation, then
 creating vtkDoubleArrays and using SetArray to pass a pointer to my
 allocated c++ arrays to the output vtkarrays. The code for setting up the
 output vtkarrays is roughly as follows

 vtkPointData *pointData = input-GetPointData();
 vtkDataArray *dArray = pointData-GetArray(i);
 vtkDoubleArray *vtkDArrayAve = vtkDoubleArray::New();
 vtkDArrayAve-SetName(dArray-GetName());
 vtkDArrayAve-SetArray(dArraysAve[i],hgrid-GetTotalCells(),0);
 vtkDArrayAve-SetNumberOfComponents(numComponents[i]);
 vtkDArrayAve-SetNumberOfTuples(hgrid-GetTotalCells());
 output-GetPointData()-AddArray(vtkDArrayAve);

 dArraysAve is an array of pointers pointing to my c++ arrays
 hgrid-GetTotalCells() returns the number of data points for my output

 I also have another mode of operation for this plugin, where I perform the
 interpolation differently, in that function, if I make the call to
 SetNumberOfComponents() some heap corruption occurs and I get a segfault
 when I try to subsequently free my c++ arrays. Commenting out the call to
 SetNumberOfComponents avoids the segfault, but then I am limited to single
 component arrays. This is the more serious bug I mentioned, initially I
 figured they were unrelated, but I can't deny the number of components
 coincidence.

 Bruce

 After averaging, I am writing the data to c++ arrays, and creating a
 new vtkDoubleArray using the SetArray() function to pass the c++ arrays.
 This works fine for 1 and 3 component arrays, however for the 9 component
 arrays paraview shows that every element is set to 0.

 If I hardcode it so that 9 component arrays become 3 component arrays
 (reading only the first 3 components from the input array), then I get the
 correct data for the first 3 components, though I obviously need the other
 6 components in the end.

 Has anyone encountered this before?

Re: [Paraview] problem in installing Paraview from source in MacOS

[Shawn Waldon]

It looks like the error is happening when building the examples.  You might
be able to get around it by rerunning CMake and turning the examples off
unless you need the examples in your build.

cd /path/to/build/dir
