Re: [Paraview] Direct link to ParaView sources not working with wget

Michael,

Try quoting the link. I guessing the shell in interpreting those
ampersands and messing things up. The following works for me.

Re: [Paraview] Send an array from client to server

[Utkarsh Ayachit]

I am sure you're misinterpreting the code. I created the extra vtkSM class
in my example only so that I can do the "SendStream" somewhere. Anycase,
I'll let you figure that out when you have the time.

Attached is the solution, there a small mistake in my origin script:

 vtkClientServerStream stream;
 stream << vtkClientServerStream::Invoke
  << VTKOBJECT(proxy)
   << SetValues
   << maxValues
   << stream.InsertArray(values, maxValues)

Re: [Paraview] Pull Downloads only

Not to my knowledge, but that'd certainly be a good feature to add. In
any case, all the files to download are listed in versions.cmake
(https://gitlab.kitware.com/paraview/paraview-superbuild/blob/master/versions.cmake).

That looks too convoluted. I haven't done this in a while so I'll need
to refresh my memory a bit. I'll make an example today and then get

Try using the "Contour" filter instead of Threshold. That will give
you a surface mesh. If you want to generate a volumetric dataset, use
the "Clip" filter with "Clip Type" set to Scalar and then enter the
scalar value to clip at.

Re: [Paraview] Axes Grid bug with 2D surfaces

[Utkarsh Ayachit]

That's indeed not supported. As mentioned in the blog post [1], the
Axes Grid is intended for the entire scene, and not for a specific
dataset. Certain implementation choices (esp for supporting parallel
rendering with distributed data) require that the axes bounds are
always greater or equal to all the data being rendered in the scene.

Re: [Paraview] Send an array from client to server

[Utkarsh Ayachit]

(hit `send` prematurely, ignore previous email)

How big is the array? For 100s of values, I'd say IntVectorProperty is
still reasonable. Any other approach will mean that those values are
not going to get saved in state files and such. For a one off push to
server side for values you don't care to be saved in state files, you
can directly call API using the vtkClientServerStream on the proxy as
follows:

  vtkClientServerStream stream;
  stream << vtkClientServerStream::Invoke
  << VTKOBJECT(proxy)
   << SetValues
   << maxValues;
stream.InsertArray(values, maxValues);
stream << vtkClientServerStream::End;

proxy->GetSession()->ExecuteStream(proxy->GetLocation(), stream);

Assuming a server-side API of `void SetValues(int count, int* values);`.

(please confirm the API, but this is pretty close to what it would look like)

True. I couldnt' decide if they should be separate or combined. I
opted for separate since it allows for nice viz like this
(http://www.kitware.com/blog/files/48_97946856.png). BTW, you can use
the "Save current values as default" button on the bottom left corner
of the dialog to preserve your setup between multiple ParaView runs.

You should be able to use the "Data Transform" group of properties for
a similar effect.

Re: [Paraview] Possible bug in recent SuperBuild?

[Utkarsh Ayachit]

Giovanni,

kwgitlab in internal Gitlab not accessible to computers outside Kitware
network. Some of the external projects are hosted there since the licensing
issues. I believe GenericIO recently went opensource. So you should be able
to update the URL in versions.cmake to the one reported here:
http://trac.alcf.anl.gov/projects/genericio.

Re: [Paraview] Segfault in ParaView 4.4 RC2

[Utkarsh Ayachit]

Matthieu,

Simply set the CMake variable OPENGL_glu_LIBRARY to empty. I think
you're pointing it to non-existant
/home/mdorier/local/mesa/lib/libGLU.so and hence the issue. If I am
not mistaken, GLU is optional only required for certain tests.

Re: [Paraview] Segfault in ParaView 4.4 RC2

[Utkarsh Ayachit]

NVM...those were from your original tarball. I thought they were
generated as an output from my run :). It's indeed an X issue in both
cases. Couple of options:

1. Do a Mesa3D build locally on the VM. Then set LD_LIBRARY_PATH to
point to the generated OpenGL libs and run ParaView/Catalyst. That'll
avoid using the GL libraries provided by virtualbox.
2. Do a OSMesa build and then rebuild ParaView/Catalyst to use OSMesa.
That'd mean you can't have the Qt UI in the same build, but Catalyst
and other scripting executables will work. That would avoid the X
issue all together. This Wiki [a] describes how to get a OSMesa
enabled ParaView build.

I've seen this happen with the view size is greater the X window size.
Try changing the ViewSize to something small, say 200x200. Does that
work? If so, you'd need to change the X window size. Other option
would be build with OSMesa support. Since you're only using this build
for Catalyst, OSMesa will circumvent all the X related issues you've
been seeing on this VM.

Re: [Paraview] Segfault in ParaView 4.4 RC2

[Utkarsh Ayachit]

What Cory suggested may be it. I can't spot anything fishy in the
CMakeCache.txt. Also try running another OpenGL enabled app, eg.
glxgears to see if that works. I believe it's provided by the
`mesa-utils` package on Ubuntu.

Alan,

I will upload the tar balls for the data. Do you want me to upload for RC2
or just wait for 4.4?

Re: [Paraview] Problem with number of arguments in a Python Catalyst script

[Utkarsh Ayachit]

Matthieu,

That's indeed the case: try adding a `cinema={}` argument to the script.

Dave, can we fix this please? Scripts generated from 4.3.1 should work with
4.4 too.

Re: [Paraview] Paraview 4.3.1 OSMesa build - QWidget::repaint: Recursive repaint detected

I have a feeling something's wrong with the OSMesa build. Try running
pvpython/pvbatch on that build. Are you able to render/save images from the
Python clients?

Re: [Paraview] Isosurface and slicing with Catalyst in C++

[Utkarsh Ayachit]

Matthieu,

Those messages are pretty much warnings. The Catalyst editions don't
have all ParaView modules and hence the Python script prompts about
missing modules. The code should still be executing properly.

Re: [Paraview] H5Part files

[Utkarsh Ayachit]

Amit,

There's a "H5PartReader" plugin that you can load using the "Tools | Manage
Plugins" dialog. Once the plugin has been loaded, you can open *.h5part
files using the H5Part reader using the File | Open  dialog.

Re: [Paraview] How to extract one face from an hexa in python ?

[Utkarsh Ayachit]

Selection extraction isn't supported yet (well not gracefully anyways)
through the Python API. However, you can use the following for similar
effect:

OpenDataFIle(...)
ExtractSurface()
GenerateIds()

threshold1 = Threshold()
threshold1.Scalars = ['CELLS', 'Ids']
threshold1.ThresholdRange = [4.5, 5.5] # to extract cell with Id 5.

Re: [Paraview] Paraview 4.3.1 OSMesa build - QWidget::repaint: Recursive repaint detected

[Utkarsh Ayachit]

Oddly, I was communicating with someone about a similar issue, but haven't
been able to get to the root cause. Do you have a debug build of ParaView?
Would it be possible to get a callstack to when than error message is
popped up?

Re: [Paraview] Isosurface and slicing with Catalyst in C++

[Utkarsh Ayachit]

Matthieu,

There indeed seems to be some issue with 4.3 editions. Since the code
worked as expected with the latest ParaView 4.4-RC2, here's what I did:

1. Created a pull request to update the CatalystExamples code to build with
4.4-RC2 here (https://github.com/Kitware/ParaViewCatalystExampleCode/pull/5).
Once Andy gets a chance to review these, they will get merged in.
2. I've uploaded Catalyst editions for 4.4-RC2 to
http://www.paraview.org/download/. I'd suggest using the 4.4-RC2 editions
along with the build fixes in the above pull request.

Note not all examples will build with the Editions (since the Editions
don't have all the code from ParaView). I verified however that
the CxxMappedDataArrayExample builds and runs with the Rendering-Python
edition that you had selected earlier.

Re: [Paraview] Programmable Filter with Multiple Inputs

That's indeed a problem, currently the order of inputs for the Programmable
Filter is cryptic and inconsistent. I am going to see what I can do to fix
this. It's a major annoyance.

Re: [Paraview] Isosurface and slicing with Catalyst in C++

[Utkarsh Ayachit]

Matthieu,

I can certainly reproduce the problem with 4.3 Catalyst editions. Let
me track it down. I'll get back to you.

Re: [Paraview] Update: Upcoming ParaView Releases (4.4 and 5.0)

[Utkarsh Ayachit]

Folks,

Just wanted to let everyone know we're closing on a ParaView 4.4
release candidate (think next week or two). If you spot any major
issues, or there's something you're keen on committing, you should do
that now.

 Folks,

 Since we're getting close to the next release, I just wanted to send out an
 email to let everyone know how we're planning to do the next release.

 + We'll do a ParaView 4.4 release will all features/fixes planned for the
 next release. This will use the older rendering code (same as previous
 release) that doesn't using OpenGL 2+ features.

 +  Following the same pattern as VTK, soon after (at the same time, if
 possible), we'll release ParaView 5.0. This will be ParaView 4.4 but with
 OpenGL2 backend.

 The main reason for this separation would be to have a fallback in case
 showstopper issues are noticed with the major rendering changes and for
 legacy systems that don't have a newer OpenGL.

 Any thoughts? Comments? Suggestions? If things go according to plan, release
 candidates should start popping up mid/late August.

 Utkarsh

 p.s. Originally, we also intended to upgrade ParaView 5.0 to use Qt 5, by
 default. However, there are a few outstanding issues with Qt 5 (some in Qt 5
 itself, and some in our testing code) and hence the upgrade to Qt 5 has been
 tabled for now.

Re: [Paraview] FullScreen and No Boraders

[Utkarsh Ayachit]

   renderWindow-BordersOff();
   renderWindow-SetFullScreen(true);

That should have done the trick. Try moving this code to right after
the RenderWIndow is created i.e. after
vtkSmartPointervtkRenderWindow::New(); (more specifically,  before
the RenderWindowInteractor is setup). If I remember correctly, the
setting up of the interactor does affect the render window state.

Re: [Paraview] paraview 4.1 and greater not getting slice representation on remote logins

Ah! I missed the info about ssh -X from different machines. Try doing a
simple Wavelet source and slice that. Does that work?

 Hi Utkarsh,

 Thanks for your super fast response.
 Using a  slice filter I also get no slice image.
 I downloaded nightly build ParaView-4.3.1-882-gbdceec7-Linux-64bit
 and I still have the problem.  Is that the most recent git/master ?

 When you say you think the problem is related to the fix you list,
 do you mean that the 15457 fix you needed to do for parallel
 slice had the side effect of causing this remote connection issue, or,
 do you mean that the parallel slice fix would hopefully solve
 the remote connection issue ?

 I tried to take a look at the code changes in the fix.
 I saw some stuff with extents.   Do you think that the
 problem is that the extent is computed incorrectly, eg
 way too small, eg 0 ?   Why would that happen only
 on the Centos-Ubuntu remote connection ?

 thanks very much,

  A workaround would be to use the Slice filter instead. It will be a

Re: [Paraview] Bug with the trace tool : Exporting view instruction not repeatable

[Utkarsh Ayachit]

Silvère,

There was a bug in the code that traced it where it picked up an
incorrect property name. As a workaround, you can change the
Rasterize3DGeometry to Rasterize3Dgeometry (note the different
case).

e.g.
ExportView('/tmp/sample.pdf', view=renderView1, Rasterize3Dgeometry=0)

 Hello everyone,

 I am used to create vector images (PDF) using the export view tool in the

 As I wanted to use it in scripts I used Start Trace to get the python

 ExportView('your_path.pdf', view=your_render_view, Rasterize3DGeometry=0)

 Problem is, the Rasterize3DGeometry option is unknown when you try and use
 it in the console (and without it you get a pixeled image).

 I looked up old messages and found this piece of code :

 rw = your_render_view.GetRenderWindow()
 exp = paraview.vtk.vtkInstantiator.CreateInstance('vtkGL2PSExporter')
 exp.SetRenderWindow(rw)
 exp.SetDrawBackground(0)
 exp.SetSortToSimple()
 exp.SetFileFormatToPDF()
 exp.SetFilePrefix(your_path.pdf)
 exp.Write3DPropsAsRasterImageOff()
 exp.Write()

 that should take care of it in a less direct way. Unfortunately, the
 instanciation fail and the object (named exp here) is undefined.

 Is it only an interface problem with python ? Is there any way to get the
 correct instance of the renderer ?

 Best regards,

Re: [Paraview] Fwd: Custom animation help? (Corrected image)

[Utkarsh Ayachit]

Jesse,

Delete is typically greyed out when there's a filter connected to that
particular source/filter. You need to delete all downstream stream filters
before you can delete the active one. In other words, you cannot delete a
filter/source in the middle of a pipeline. You can only delete the sinks
or leaves.

 When you load a state file, you get the chance to update the data file

 Greetings all,

 which made it a huge file. The JPG is now attached.

I’m trying to make an animation in Paraview. I took a stab at it
 before with Paraview, but I recall it as being tedious. Maybe I can get
 some pointers from the experts.

   So, the attached imaged is a cube view of the electromagnetic
 response over sea ice. What Im trying to do with this animation is two
 things:

   1.) Move the horizontal slice and Y-Z vertical slice (the slice
 without the tubes) up and down, and side to side, respectively, such that
 as if you selected the particular slide in the Pipeline browser, you 
 could
 drag the slice in question and move it manually to see the different
 responses. Therefore I’m trying to automate it.

   2.) Rotate it about the z-axis 5 degrees (to about 180) at each
 iteration and return, then rotate it 5 degrees at each iteration about 
 the
 y-axis (till about 45 degrees) and return.

 Alan,


 Attached is a state file (using can.ex2) which indeed uses numpy.trapz()
 to do the work. It needs a small patch to be applied to VTK (attached) to
 avoid a segfault.



 The Programmable Filter adds a new row-data array named trapz which is
 the result of the operation (it's repeated so we can add it to RowData
 rather than field data.

 2)  Then, integrate the result of the volume integral over time

 The IntegrateVariables filter works just fine to integrate over the
 volume, and I can plot the results of it over time by selecting RowData
 from the PlotSelectionOverTime filter.  I just can't figure out how to do
 #2 - integrate these results over time with something like numpy.trapz or
 scipy.integrate.cumtrapz.



 I feel like this has probably been asked a million times, but I still seem
 to have trouble with it.  I think I usually fall back to other post
 processing tools.  Can this be done all in Paraview?

Re: [Paraview] Update: Upcoming ParaView Releases (4.4 and 5.0)

[Utkarsh Ayachit]

Lester,

ParaView 4.4  won't have any major OpenGL related changes so it should work
on platforms ParaView 4.3 or earlier worked. ParaView 5 (with its use of
OpenGL 2.1/3.2 features) should indeed still work on Windows 7/8 with
relatively modern drivers. Note, OpenGL 3.2 is still quite old (~2009). If
you're using remote-desktop, however, you may want to switch to using VNC.
Remote desktop uses a software OpenGL implementation, which (when last I
checked) was only OpenGL 1.1 compatible.

(cc-ing Ken to correct me if I am mistaken)

Re: [Paraview] Pipeline's filters and multiblock order

[Utkarsh Ayachit]

The Pipeline Browser shows the filters in pipeline order (or the order
they are created in). This can't be changed, I am afraid. BTW, rather that
using that script, you can use the Extract Block filter to extract blocks
of your choice if you're only interested in a few blocks (or few groups of
blocks). That may make it easier to use. In the Block Indices widget for
the Extract Block filter, you can use Ctrl+F (or Cmd+F) to search for a
block by name.

Re: [Paraview] Output data across all timesteps with Python

[Utkarsh Ayachit]

If you know the timestep values you're interested in, you can do the
following:

for t in [0, 0.001, 0.002]:
  writer = CreateWriter(.../foo_%d.csv % t, source)
  writer.FieldAssociation = Points # or Cells
  writer.UpdatePipeline(t)
  del writer

 Hello Everyone,

 I am trying to write a python script to output data for each time step. I
 know to use the following script to save data for one time step:

 I'm curious how I may do this for every time step?

 Thank you for your help,

Re: [Paraview] paraview python script : Delete(renderView1) does not free memory

[Utkarsh Ayachit]

Delete() will only remove the render view, not all other proxies that were
created as part of the state loading operation. The following script should
do the trick:


from paraview.simple import *

def ResetSession():
pxm = servermanager.ProxyManager()
pxm.UnRegisterProxies()
del pxm
Disconnect()
Connect()

for i in range(0, 10):
ResetSession()
servermanager.LoadState(/tmp/sample.pvsm)
renderView=SetActiveView(GetRenderView())
Render()

 I was monitoring the memory used by machine, after some time steps the
 memory used by the machine is whole RAM. Can anybody tell me what I am
 doing wrong here.

 I appreciate your time and support.

Re: [Paraview] Plot cumulative integral over time of a variable

[Utkarsh Ayachit]

Alan,

Attached is a state file (using can.ex2) which indeed uses numpy.trapz() to
do the work. It needs a small patch to be applied to VTK (attached) to
avoid a segfault.

The Programmable Filter adds a new row-data array named trapz which is
the result of the operation (it's repeated so we can add it to RowData
rather than field data.

  Question from a user:

 I would like to use paraview to do the following:

 1)  Integrate a nodal variable over a volume (IntegrateVariables
 filter does this)

 2)  Then, integrate the result of the volume integral over time
 (cumulative integral)

 The IntegrateVariables filter works just fine to integrate over the
 volume, and I can plot the results of it over time by selecting RowData
 from the PlotSelectionOverTime filter.  I just can't figure out how to do
 #2 - integrate these results over time with something like numpy.trapz or
 scipy.integrate.cumtrapz.

 I feel like this has probably been asked a million times, but I still seem
 to have trouble with it.  I think I usually fall back to other post
 processing tools.  Can this be done all in Paraview?

Re: [Paraview] Impossible to see a movement.

[Utkarsh Ayachit]

That would be questions to ask to the folks who developed the reader, I am
afraid. I suspect the Wrap button expected an array of certain shape/name
and that's missing in your dataset. I suspect its the fact that your DEPL
array is a 4 component array, rather than 3 -- but that's just a wild guess.

 Typically, movement comes from one of the following:

 It is up to the specific reader class to decide what to do so who exactly
 reads what depends on the file type. If the data is not well distributed,
 apply the D3 filter to make paraview repartition the read in data amongst
 the processors.


 I did the following to start a single pvserver on each of two hosts:

 $ mpirun r219i0n0,r219i0n1 -np 1 /usr/bin/env DISPLAY=:0
 /u/jcbecker/ParaView-4.3.1-Linux-64bit/bin/pvserver --client-host=pfe20
 --use-offscreen-rendering

 After I connected to the first pvserver, and opened the file, I tried to
 apply the D3 filter, but it was grayed out.

 Paraview declined the connection gracefully when the client was built with

 successful.

Re: [Paraview] pvserver segfault

[Utkarsh Ayachit]

Can you try turning off Display Lists? It's an option under the Settings
(Render View tab) dialog. You'll need to restart ParaView after making this
change. I suspect the graphics driver is giving up while building a large
display list. Display lists will be a thing of the past once we update the
rendering backend in the next release of ParaView, FYI.

Re: [Paraview] Viewing data from multiple times on an xy-plot

[Utkarsh Ayachit]

Not in the same view, but the Comparative versions of the line/bar chart
views allow you see multiple timesteps side by side. You can use the
Comparative View Inspector to add Time as the parameter to compare and
then setup the timestep values of interest for each of the views.

Re: [Paraview] Import h5py in python shell

Another trick to try (no guarantees :) ) is to install Python 2.7.2 (64bit)

h5py from pvpython. You'll need to extend  the sys.path variable to find

Re: [Paraview] Fwd: Problems in rendering when raw image is resized

[Utkarsh Ayachit]

I am not entirely sure what 1 is. However, for 2, try changing the Scalar
Opacity Unit Distance from the Properties panel. ParaView will set it to
a value based on the data spacing after the first Apply. If you change
the spacing after that, you can use the Reset using current data values
button next the option on the Properties panel to recompute using the
current data values.

 Do you have any idea about it, please?

 1) When I import a 3D raw image, if I set the data spacing, i.e., the size
 of each voxel, to 1,1,1, I can correctly visualize and rotate the image.
 However, if I set the voxel size to the values I need
 (5.549E-6,5.549E-6,5.549E-6), the image is rendered as if clipped when
 turned to certain angles (please see picture thisShouldBeCuboid.png
 attached).

 2) Another problem for the same image is that, if the data spacing is set
 to 1,1,1, I get a certain contrast between grey and white (size1.png). If
 it it set to 0.1,0.1,0.1, the grey color becomes whiter (size01.png).
 Finally, when it is set to the correct small size, it is completely white.

Re: [Paraview] Troubles with exporting selection labels from current ParaView render view

[Utkarsh Ayachit]

Nenad,

DataLabelRepresentation is a subproxy of the GeometryRepresentation and
that has been the case since as long as I remember. That means that when
you iterate over representations in the view, you'll never see a separate
DataLabelRepresentation proxy. Each source proxy has a GetSelectionOutput
method that you can use to get the source proxy which is doing the
extracting tasks to extract selected points. To see if the source proxy
has a selection set, you can use the
vtkSMSourceProxy::GetSelectionInput() method.

Hope that helps.

 Utkarsh,

 Thank you very much for answers about creating and initializing

 But, my exporting plugin (my first message) is still unable to export
 labels which I get when try selecting several points. Here is what I
 do:

 1. Create Sphere and apply Elevation filter on it (I turn OFF 3d widget),
 2. I select several points and in Selection Manager I select Elevation
 for Point Labels,
 3. In following code snippet I get only 2 message boxes (one of Sphere
 and one for Elevation - both GeometryRepresentation),, but, there is
 no DataLabelRepresentation.
 4. I know how to extract labels parameters at this level (Selection*
 parameters from representation), but not set of points over which are
 generated labels,

 // for all sources
 for(i = 0; i  sources.size(); i++)
 {
 // get source
 pqPipelineSource* source = sources.at(i);

 // for every source's output port, process it
 for(output_port = 0; output_port 
 source-getNumberOfOutputPorts(); output_port++)
 {
 // traverse all representations
 for(j = 0; j  source-getRepresentations(output_port,
 active_view).count(); j++)
 {
   QMessageBox::about(NULL, ,
 GetCurrentSourceRepresentationSMName());
 }
 }
 }

 Should I try to catch
 pqSelectionManager::selectionChanged(pqOutputPort*) to get data
 structure over which are points which I can compare with data
 structures extracted from vtkRenderWindow to generate labels?

 Thanks for help in advance!

  Neither of these are really supported. Look at
  vtkSelectionRepresentation. If you can think of ways of tagging the
  actors added by the representations used internally by this class, I
  am all ears.

You've accidentally enabled Auto Apply. You can turn it off from the

 I'm having a problem with Paraview immediately applying a filter once I

 started doing it this way. Previously, I had to acknowledge the application
 of the filer by clicking the 'apply' button before it would do so. Any help

Re: [Paraview] How to automaticaly generate probe location points?

[Utkarsh Ayachit]

Joice,

First question do you want probe location or select a cell/point? If you
can describe the workflow you'd use to do this manually for 1 point, I'll
know better what approach might work for you.

Thanks

 This demand a significant amount of time to do manualy.
 I would like to know if it is possible to automaticaly generate the probe
 location points.
 And if it is possible to automatically plot selection over time to this
 same generated points.

 I found this explanation:

 is not clear to me how to do it.

 I prefer to do it without programming.

 Thank you.

Re: [Paraview] Import h5py in python shell

[Utkarsh Ayachit]

ParaView packages its own Python. You'll either need to build ParaView from
source using the Python installation you have or install h5py in the Python
packaged with ParaView.

 I tried to import the module by providing the path to the package, using

 import

 - import the module using the imp package and providing the full path to

 However, both methods failed to load h5py, returing the following error :

Re: [Paraview] Running regression tests

Look at what we do for ParaViewSuperbuild [1, 2]. That may give you

 I build/install each release of ParaView on a number of platforms, so I am
 looking for a way to validate correct build and installation, and also to
 check correct performance of our own plugins etc. A subset of the standard
 regression tests would probably be sufficient for validating correct
 installation.



 Step-by-step instructions would be awesome – if available.

 Hi,

 I’ve been using a python script to post-process and visualise large 
 structured grid files. It works great but the grids I am visualising are of 
 different dimensions (let say either 512x128x512, or 1024x256x1024).

 In the script pipeline - see snippet below -  I extract a subset (top cell 
 layer in the Y direction) from the whole dataset, using ExtractSubset filter.

 At this stage for the 2 input files dimensions above, I need to modify the 
 script and correctly set extractSubset1.VOI values manually.

 Is there a method that I could use in the script to get the dimensions (or 
 extent) of the structured grid, so I can make the script extract the top 
 layer I’m interested in for any grid dimension?


 snip
 from paraview.simple import *

 inputPvts = XMLPartitionedStructuredGridReader(FileName=[fname])
 inputPvts.PointArrayStatus = ['velocity']

 # get active view
 renderView1 = GetActiveViewOrCreate('RenderView')
 renderView1.ResetCamera()

 #get the 4 uppermost cells
 extractSubset1 = ExtractSubset(Input=inputPvts)
 extractSubset1.VOI = [0, 512, 127, 128, 0, 512]
 extractSubset1.SampleRateI = 1
 extractSubset1.SampleRateJ = 1
 extractSubset1.SampleRateK = 1
 extractSubset1.IncludeBoundary = 0
 doCoolStuff...
 /snip

 So far, I’ve tried reading the VOI from the extractSubsetFilter, but the 
 indexing of the extent is not showing the grid dimensions:

 dimensions = extractSubset1.GetPropertyValue('VOI')
 print dimensions

 But that returns an array [0, -1, 0, -1, 0, -1]. And I can’t seem to be able 
 to use relative indexes in the filter like: extractSubset1.VOI = [0, -1, -2, 
 -1, 0, -1].

 Any thoughts?

 Cheers

 Guillaume

ParaView has certain overhead when a new source/filter is created. It
will need some more profiling, but creating 500+ readers would indeed
push things closer to that limit. ParaView/VTK typically uses

the same dataset. Here's a Script for the Python programmable filter

Re: [Paraview] deforming sphere-like grid to object

[Utkarsh Ayachit]

Another alternative.

- create a filter that deforms the sphere up to a specific iteration
N. This filter will have a property to set the current iteration
number.
- setup an animation to change the iteration number.

(assuming deforming to an arbitrary iteration is just as expensive as
going to a i+1 iteration).

 Edit:

 After doubling the amount of lifetime experience with paraview or vtk since
 my last email, I think what I ought to do is create a filter that does a
 single iteration of shape deformation. Then I'll create a script that
 alternates calling this filter and rendering 500 times or so.

 Let me know if that sounds incongruous with how Paraview works.

 Background Idea:The points on the initial sphere should deform in a way that
 minimizes the total 'energy' of the blob: edges should coincide with sharp
 contrast in the background volume; surface normals should be minimial.

 Thanks again,

 Hi all,


 Here's what I'd like to do using python scripting.
 1) Initialize a set of points and edges that look like a sphere using
 sphere=Sphere()
 2) deform that set of points (and edges) to match a volume whose high
 intensity region is also blob-like using an active shape model
 3) visualize the evolution of the sphere deformation using paraview.

 I only tell you so you can stop me if I'm doing this in a suboptimal way.

 My immediate question is simply how can I extract/change the coordinates
 of a Sphere() object? Are the points of a sphere object constrainted to
 forever occupy a sphere shape?

 Best,
 Chris

Re: [Paraview] volume comparison

[Utkarsh Ayachit]

ParaView/VTK really doesn't support mixing two overlapping volumes.
Without going into the details, suffice it to say that the rendering
implementation will result in one of the volumes always on top of
the other. An alternative is to to render the volumes in 2 separate
views, side-by-side and then link the camera together to interact
simultaneously with the two views -- enabling similar comparison.
Another option is to extract isosurfaces (contours) from the two
volumes and then render those as surface with opacity  1. Multiple
overlapping surfaces with translucency should work fine.

 Hi,

 I have two 3D image that I would like to compare to see  if they are the

 different colors with some opacity.

 This presents some difficulty. In my mind I would be able to have 2 volumes
 overlayed, full control of the color map of each volume, and be able to
 control rotation and translation of each volume individually.

 If that's not possible directly in the GUI, maybe it's possible through the
 python console?

Okay I must be missing something very obvious here, but I am totally

Just focusing on EventHandlers.cpp for now.

Are you saying EventHandlers::DataRepresentationCreated() isn't called

Re: [Paraview] Installing ParaView 4.0.1 on Nodes For Rendering Frames -Slow Rendering w/ Python

[Utkarsh Ayachit]

Are you using x forwarding when you connect to these machines? What is
localhost:10.0 display to? Try running some other X-based application
like gvim, or glxgears etc. and see where that window pops up. If it's
popping up on your laptop, you're using X forwarding. Every render on
the server will then be forwarding X calls to your laptop and that
would explain the slow down.

If there an X server running on the remote site? If so, check with
your sysadmin to get access to that X if possible. If not, you'll need
to recoming with OSMesa, I am afraid.

 very very slow rendering for each time step with the offscreen rendering

 trying to run my code on. On my local machine it takes less than a second
 for each time step I am rendering to be outputted with the same settings and
 I am not spinning anything  up like pvserver - on the node instances I have,
 it is taking well around a minute or probably more for each frame.

 I have read through a lot of similar issues and the documentation for X
 connections but I am not having any luck. The default DISPLAY is set to the
 localhost:10.0 and I have tried changing that to the localhost:0.0 but it
 gives me the bad -X connection error. From there, I followed previous
 mailing list instructions and tried spinning up the pvserver (I don't know
 why since I am not trying to serve anything just render frames) but I get an
 error with the shared libraries that they're too short. I am using the
 default downloadable version of 4.0.1 since I want to try and keep this as
 simple as possible but I don't know if these have the mpi turned on by
 default. Has anybody ran into this Bad X Connection issue and found an easy
 way around it besides messing with the OSMesa and recompiling? I'd really
 appreciate any pointers :)

Step into createDataRepresentation in a debugger. You'll see one of

yet. Try making the slot connection to a queued connection that way
ParaView gets the change to setup the representation object.

  2. vtkSocketCommunicator::GetVersion() returns different values on the
 two connecting processes (Current value: 100).
  3. ParaView handshake strings are different on the two connecting
 processes (Current value: paraview.4.3).
 **

 In this case, both server and client are using same Paraview installation
 and i disabled both firewall and selinux to eliminate the possible error
 sources that might cause the problem. The server is also started using
 following command,

 [turuncu@epsilon-lnx CFullExample2]$ pvserver --server-port=2
 Waiting for client...
 Connection URL: cs://epsilon-lnx:2
 Accepting connection(s): epsilon-lnx:2

 and the client code is running as follows,

 [turuncu@epsilon-lnx CFullExample2]$ ./CFullExample2
 SampleScripts/feslicescript.py

 I enabled live visualization by setting it True and proper server address
 and the port in the Python coprocessor code. I also tried to connect
 server from another machine directly using Paraview and it is working. At
 this point, i just need help to find the problem.
 Best Regards,

Re: [Paraview] Switching Between Readers

[Utkarsh Ayachit]

Kevin,

Can your reader tell if it can read the file irrespective of its
extension? If so, just implement a int CanReadFile (const char
*fname) method on the the reader classes that will test a file. Now
you can have two reader supporting the same extension and ParaView
will create the correct reader automatically. There can be multiple
reader supporting the same extensions even without this CanReaderFile
too. In that case, ParaView will automatically popup a reader
selection dialog.

 I was wondering if there was a way to instantiate a superclass that, let's
 say, can switch between vtkPolyDataAlgorithm and vtkImageAlgorithm.

 I have a reader that (as of now) converts the data within a protobuf file to
 image data.

 But currently, I have multiple protobuf files with different information.
 However, the file extension is still .pbuf, and it seems that the reader xml
 parsers the files based off this input.

 So would it be easier to change the filename? Or is there a way to switch
 between the two algorithm classes?

 Thanks for your time!

Re: [Paraview] Troubles with exporting selection labels from current ParaView render view

[Utkarsh Ayachit]

 - Strange 1: I don't have anymore instance in
 DataLabelRepresentation for Elevation pipeline source (btw, during
 this traversing I get only one actor),

I don't follow. DataLableRepresentation is indeed created for every
representation shown in the render view.


 - Strange 2: When I traverse vtkRenderer's actors, I get 2 actors
 (sphere mesh and actor with selected points), but, I'm unable to
 connect selection label properties (which are tied with Elevation
 pipeline source actor - sphere mesh) and mesh with selected points /
 cells.

Remember that label actors are added to the 2D / non-composited
renderer, not the same as the 3D renderer. Which renderer are you
looking at?

 Q1: How to identify actor from vtkRenderer which contains selection
 points / cells and get selection properties from this actor or

 Q2: How to identify actor from pqPipeline source on which are selected
 points and how from appropriate representations to get actor which
 contains selected points / cells?

Neither of these are really supported. Look at
vtkSelectionRepresentation. If you can think of ways of tagging the
actors added by the representations used internally by this class, I
am all ears.

Re: [Paraview] Client/server version hash mismatch, even when versions are the same

CS,

What're the exact error messages reported on the client as well as the
output terminal for the server? Can you post the complete text please?

 Dear ParaViewers,

 I am attempting to set up a client/server connection between a default
 installation of ParaView 4.3.1 on the client side and an OSMesa build --
 presumably also 4.3.1; built according to the wiki's instructions at
 http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D -- on the
 server side. Both computers have graphics hardware; using an ssh tunnel is
 not acceptable for our purposes due to the requirement to disable all
 security using *xhost+*. The computers also have default installations of
 4.0.1. Both are running VTK 5.8.

 Despite the ParaView and VTK versions on both ends being identical, I
 receive Client/server handshake failed and Client/server version hash
 mismatch errors every time I attempt to connect. What could be the cause
 of this issue?

Re: [Paraview] Glyph filter instead of legacy glyph filter

[Utkarsh Ayachit]

 Is there a way that I can use the newer “Glyph” filter in my visualization
 and remove the constant vectors perpendicular to the y-axis?

You can use the Vectors drop-down box to choose which vectors to use
for orienting the glyph. You can use Scale Mode to control how to
scale the glyph.

Checkout Chapter 5, Section 5.7.8 for the ParaView Guide [1] for more details:
