[Paraview] Disconnect and save animation

[Utkarsh Ayachit]

Folks,

I am trying to get a feel is anyone uses this functionality at all. If
not, we'd like to remove it as it simplifies a few interactions,
besides reducing code complexity.

The functionality I am referring to allows one to disconnect from a
remote server and then save animation on the server before the server
exits but after the client has disconnected.

Thanks
Utkarsh

Re: [Paraview] ParaView 5.4.1 | Segmentation Fault

[Utkarsh Ayachit]

Thomas,

Check your graphics drivers. You can use tools like `glxinfo` to tell
you which OpenGL version is supported. ParaView now requires 3.2 or
newer. If you cannot upgrade your graphics drivers, you can use
software OpenGL implementation packaged by ParaView binaries as
follows:

.../paraview --mesa

Hope that helps,
Utkarsh

Re: [Paraview] display problems paraview

[Utkarsh Ayachit]

This may be same as the issue described here:
https://gitlab.kitware.com/paraview/paraview/issues/17499
Try switching to NVidia GPU, if you can, if Intel graphics is indeed
the issue in your case.

Re: [Paraview] Can I tie Z Axis Grid labels to the unscaled range of the Scalar Value used in the Warp By Scalar filter?

Sounds like a bug. If you can put together a small example to
reproduce the issue and report it here [1], we can track it down.

Re: [Paraview] Display Problem

[Utkarsh Ayachit]

X. Y.,

Your cells seem odd. Try changing the representation type to
"Wireframe", you'll see a grid. Then use spreadsheet view, in "Cell
Data" mode, clicking on each cells to see if the cell seems correct.
You have cells that form lines and hence the default "surface"
representation is failing to render it correctly.

Re: [Paraview] Can I tie Z Axis Grid labels to the unscaled range of the Scalar Value used in the Warp By Scalar filter?

[Utkarsh Ayachit]

Another option is to use the "Data Transform" properties on the Axes
Grid. In the "Edit" Axes Grid dialog, if you press the gear icon to
show advanced properties, you'll see the "Data Transform" properties.
For example, if I scale my dataset by (1, 1, 10), I can set the "Data
Scale" to (1, 1, 10) and I'll get labels matching the original
unscaled range.

Hope that helps.

Re: [Paraview] OpenGL Vendor

To add to what Ken said, the "Client Information" tab shows you info
about OpenGL for the "paraview" executable, while the "Connection
Information" gives you info for the "pvserver", if any.

Re: [Paraview] Multiple identical "sources" proxies in a saved XML state file (GlyphType)

[Utkarsh Ayachit]

Artem,

You raise good points. In reality, only saving the state of the
currently selected proxy from proxy-list domain should be sufficient.
There are challenges to doing that given the current implementation,
however. Let me try to figure out a viable solution and get back to
you.

Re: [Paraview] Error when trying to turn on Volume Rendering for large tetrahedral data in ParaView 5.4.1

Joe,

Sorry, doesn't ring a bell. One thing to try is to turn of "Use Data
Partitions" (see [1]) if your data is already partitioned between
ranks such that we can build a sorting order.

By selecting the "Chart View", I meant simply click on the view that's
showing the plots after you applied the "PlotOnIntersectionCurves"
filter. That will activate the view. Now, when you choose File |
Export View, you'll export the contents of the selected view.

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

[Utkarsh Ayachit]

Even with fb13726dbfdcb5479c393720abaf8234edd42609, it fails to build. I'll
wait for you to update your code to build with latest ParaView before
testing it. A quick look at the "AddToView" method and I don't see anything
wrong with it, so it will need some debugging.

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

[Utkarsh Ayachit]

Maybe if you share the code for vtkLIC3DRepresentation I may be able
to offer suggestions. You could also try getting a access to some
other linux machine on which you should be able to reproduce the
issue.

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

[Utkarsh Ayachit]

My guess would be that you're accessing a nullptr in
`vtkLIC3DRepresentation::AddToView`. I'd recommend doing a debug build
of ParaView, and then attaching a debugger to confirm and fix.

PlotOnIntersectionCurves essentially slices the dataset using a
implicit plane. The points you get are indeed the insection points
between your polydata and the plane and hence there's no control over
how many points there can be, besides what's determined by your mesh.

If you can share the sample data (feel free to do it off the list,if
you'd like), I can see what other options may work.

>Also,  upon saving, three files were produced file0.csv, file1.csv, file2.csv,

Are you using "save data"? I'd suggest selecting the "Chart View" and
then using "Export View" option to export the curves. That will give
you a since CSV for the fields you've selected.

Not in 4.1.0. I believe this was fixed in 5.2. 5.2 onwards, you can
create and show multiple rulers.

Re: [Paraview] ParaView - Variables and different Time Steps

[Utkarsh Ayachit]

Carolin,

Check this post out:
https://blog.kitware.com/improved-vtk-numpy-integration-part-5/

The input to your filter as a vtkMultiBlockDataSet with each block
being a timestep, you can access individual arrays as described in the
post or you can use the following approach:

from paraview.vtk.numpy_interface import dataset_adapter as dsa
dataset_time0 = dsa.WrapDataObject(inputs[0].GetBlock(0))
dataset_time1 = dsa.WrapDataObject(inputs[0].GetBlock(1))

etc.

Re: [Paraview] CS Wrapper for plugins ignores preprocessor variable

[Utkarsh Ayachit]

Two approaches:

1. put the two is separate headers and pick the approach header based
on if _DETAILED was defined at cmake configure time.
2. change header as follows:

#ifndef __VTK_WRAP__
#ifdef __DETAILED
#define vtkAlgorithm vtkMultiBlockDataSetAlgorithm
#else
#define vtkAlgorithm vtkRectilinearGridAlgorithm
#endif
#endif

class ... MyPlugin: public vtkAlgorithm
{
   static MyPlugin* New();
   vtkTypeMacro(MyPlugin, vtkRectilinearGridAlgorithm);
#ifndef __VTK_WRAP__
#undef vtkAlgorithm
#endif

};

Here, the wrapper will not provide any API on the the real superclass
but most likely, you only care about API in vtkAlgorithm to be
wrapped. See vtkFloatArray as an example on how this is done.

Re: [Paraview] ParaView - Variables and different Time Steps

[Utkarsh Ayachit]

The easiest way to do such a thing is as follows:

1. Apply Extract TimeSteps filter to your reader/source to choose the
timesteps of interest.
2. Apply Group TimeSteps filter to it to group the timesteps extracted
in (1) into a mutliblock dataset with 1 block for each selected
timestep in order.
3. Now add your programmable filter to (2) and you can access all
timesteps of interest as blocks in your input.

You can skip (1) if you want to use all timesteps, and not just a subset.

Re: [Paraview] About CmakeLists.txt for paraview plugin

[Utkarsh Ayachit]

Doesn't your plugin need other classes from VTK/ParaView? If so, you
can't mix and match. I am afraid you'll have to build ParaView from
source and then compile the plugin against it.

Re: [Paraview] PV client-server: browsing remote files

[Utkarsh Ayachit]

Robert,

Sorry I missed the email earlier. What you have as an alternative is
indeed a reasonable approach. Once can also use ParaView's
infrastructure used by the file dialog, but it's a little clunky
currently, since it needs to be pythonified for easier user.

Here's how you'd do this with 5.4.1.

from paraview import servermanager as sm

helper = sm.misc.FileInformationHelper()
helper.DirectoryListing = 1
helper.WorkingDirecotry = "'/path/to/data/on/remote"

pvinfo = servermanager.vtkPVFileInformation()
helper.GatherInformation(pvinfo)
for a_pvinfo in pvinfo.GetConents():
   if a_pvinfo.GetType() == a_pvinfo.FILE_GROUP:
 for b_pvinfo in a_pvinfo.GetContents():
assert b_pvinfo.GetType() == b_pvinfo.SINGLE_FILE
print (b_pvinfo.GetName(),  b_pvinfo.GetFullPath())
   elif a_pvinfo.GetType() ==  a_pvinfo.SINGLE_FILE
  print (a_pvinfo.GetName(),  a_pvinfo.GetFullPath())

This will print all files in the directory.

See vtkPVFileInformation docs
(https://www.paraview.org/ParaView3/Doc/Nightly/www/cxx-doc/classvtkPVFileInformation.html)
for more API details.

Hope that helps.

Re: [Paraview] Python shell, os.environ

[Utkarsh Ayachit]

Randy,

No, `os` hasn't been hijacked by PV.  Here's what I get on Linux.

./bin/pvpython
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ["FOO"]
'12'


I suspect it's something to do with App bundles on macOS and what
environment variables they see based on how you launch them. I can't
remember that of the top of my head, but that's where I'd start
looking.

What happens if you don't split, instead close the current view and
create a new render view in its stead? Do you get the same segfault?

Re: [Paraview] animation: files, pgmable source

[Utkarsh Ayachit]

Randy,

Here's how I'd proceed.

1. Create a programmable source to read a file series as a temporal
dataset. (you have this already).
2. Let the users use ParaView to save animation or screenshots once
they are satisfied.
3. You can put the "Extract TimeSteps" filter after your reader
(before any of the other pipeline) and make it filter timesteps. It
allows filtering over a range of timesteps with an arbitrary interval.
So your users can change this to choose which subset they are
interested in. I'd also point to the "Time INspector" so user can see
what timesteps ParaView is taking into consideration.

Re: [Paraview] animation: files, pgmable source

[Utkarsh Ayachit]

Randy,

Mind explaining to me what;s your ultimate goal? The way I see it,
there are two options:

1. Provide your users with a state file that they load in ParaView UI
and then use the UI to save animation or images. Use the UI to move
back and forth through the timesteps, etc.
2. Provide your users with a Python script that they run using
pvpython to save out screenshots or animations based on command line
arguments.

Which one are you aiming for? Or is it something else?

Not entirely sure how, unless some incorrect libraries are getting

Re: [Paraview] animation: files, pgmable source

[Utkarsh Ayachit]

Randy,

You attempting to mix the Python scripting for data processing and
Python scripting for batch scripting. The two environments are
separate. Here's how I'd tackle it.

1. Make your "Programmable Source" become a temporal source i.e.
report to ParaView that it can produce timesteps matching the files
your file series. See [i]. If you get this right, you shuold be able
to render through all the files by hitting "Play" in the VCR control
in the UI.
2. Now you can write a batch script that either loads the predefined
pvsm state file or builds up the pipeline in Python itself and the
either uses `SaveScreenshot` or `SaveAnimation` to save out the
animation.

You can then mix in camera animations too. You can always use the
Python tracing in UI to figure out how to save images and/or animation
in the batch scripting environment.

Hope that helps.
Utkarsh

Re: [Paraview] Assemble Variables into Tensor

[Utkarsh Ayachit]

Nick,

You can use the *Programmable Filter* instead with something like the
following script as the *Script*:


from paraview.vtk.numpy_interface import dataset_adapter as dsa

import numpy

def make_tensor(xx,yy,zz, xy, yz, xz):

  t = numpy.vstack([xx,yy,zz,xy, yz, xz]).transpose().view(dsa.VTKArray)

  t.DataSet = xx.DataSet

  t.Association = xx.Association

  return t


xx = inputs[0].PointData["sigma_xx"]

yy = inputs[0].PointData["sigma_yy"]

zz = inputs[0].PointData["sigma_zz"]

xy = inputs[0].PointData["sigma_xy"]

yz = inputs[0].PointData["sigma_yz"]

xz = inputs[0].PointData["sigma_xz"]

output.PointData.append(make_tensor(xx,yy,zz,xy,yz,xz), "tensor")

Re: [Paraview] FEM

[Utkarsh Ayachit]

Paul,

Welcome to the community!

If your data is not in one of the large number of formats ParaView
already supports, using Python to read an map to VTK data model sounds
like a reasonable strategy. The "Programmable Source" would be the way
to go. The ParaView Guide has examples that should help you get
started.

Re: [Paraview] Python Scripting - Acess vtkOpenGL cameras from .pvx files information

[Utkarsh Ayachit]

Afraid not. One potential work around would be you build the
transformation matrix and set that on the camera. You can build the
matrix yourself by changing the order of rotations.

I've responded to the thread. Please note that Thursday-Sunday was a
holiday in the US, hence mailing list responses were expected to be
slow.

While I am not sure which conversation you're referring to or whom you
were having that conversation, it's believable that there was
confusion between which data transfers you were referring to. All
communication between filters in a Catalyst in situ session is via
MPI. Only when you start doing "live" is when you encounter TCP. With
Live, currently the data transfer between the insitu ranks and the
"pvserver" ranks used for visualization is via TCP. Live support, in
my mind, is still in the early life cycle and needs more development
for production use.

Catalyst is indeed being actively developed and maintained. While we
try our best, responding to every mailing list inquiry can be quite
difficult. We do offer consulting services [1] if you want to work
Catalyst development team directly.

Hope that helps.

Re: [Paraview] server-side InvokeEvent(...) doesn't call client-side observer

[Utkarsh Ayachit]

Catalyst live-session is managed this custom engineering from both the
client and the server side. Hence it's not a mechanism that arbitrary
filters can use to communicate events from server to client. If you're
interested in how Catalyst live sessions manages this, start by
looking at vtkSMLiveInsituLinkProxy and vtkLiveInsituLink classes.
Following the code path for NEXT_TIMESTEP_AVAILABLE might be helpeful.

Re: [Paraview] Segfault with simple C++ filter derived from vtkMultiTimeStepAlgorithm

[Utkarsh Ayachit]

Mark,

You're simply missing a call to `this->SetNumberOfOutputPorts(1)` in
your constructor. That will get past the segfault.

Besides that, look at `vtkTemporalArrayOperatorFilter` as an example
for how to overload `RequestDataObject` to create correct output
dataset type, `RequestInformation` to determine which timesteps are
available, and `RequestUpdateExtent` to request a set of timesteps.

Re: [Paraview] steps to add class with ClientServer and Python wrapping

[Utkarsh Ayachit]

I'd suggesting starting simple and just adding to existing modules in
ParaView. Once you are familiar with the CMake code, you can experiment
with adding separate modules.

Re: [Paraview] steps to add class with ClientServer and Python wrapping

[Utkarsh Ayachit]

Where are you adding your classes? If you add them to one of the "modules"
e.g. ParaViewCore/VTKExtensions/Default, you'd only need to add them to the
CMakeLists.txt and they'd get wrapped. You'll then need to add a XML config
for the proxy e.g
in ParaViewCore/ServerManager/SMApplication/Resources/filters.xml. That
should be it.

Another option is to add a new module. You can also add a new "module". See
`ParaViewCore/VTKExtensions/Points/`. You can have the source directory
external to your ParaView source, and in your build simply set
`PARAVIEW_EXTERNAL_MODULE_ROOTS` CMake cache variable in your ParaView
build to include the directory containing your new module's dir. You will
need to manually enable the module in CMakeLists.txt as well as ParaView
wont' enable it by default.

That sounds like a bug to me. `sum_per_block` should work as you

Alas no. There's no notion of current state file in ParaView and hence

Re: [Paraview] Remote rendering with pvpython + grab remote image data

By default, ParaView will do remote rendering, if possible when the
geometry size exceeds ~20MBs. You can change it as following to force
remote rendering for all data.

...
simple.Show(simple.Cone())
view  = simple.GetActiveView()
view.RemoteRenderThreshold = 0

Re: [Paraview] Equally spaced points on a slice (for the streamlines)

[Utkarsh Ayachit]

Is the slice axis aligned? If so, you can use a regular source eg. Wavelet
or Mandlebrot to generate the evenly spaced points by setting the extents
appropriately.

Re: [Paraview] Python Scripting - Acess vtkOpenGL cameras from .pvx files information

[Utkarsh Ayachit]

Leo,

You can't access it in Python since the Python script is not run on the
server side. If your goal is to debug what thet camera is set to, you can
put cout's to print the camera in
`vtkCaveSynchronizedRenderers::HandleStartRender`. That's where the local
camera on each rank is "prepped" for rendering a frame.

[Paraview] ParaView Release Roadmap

[Utkarsh Ayachit]

Folks,

We have a change in the ParaView release plan, as follows:


*1. ParaView 5.5 October/November 2017 release has been postponed.*
We have already had 3 releases this year, hence we have decided to postpone
the 5.5 release. The next release will be according to the release plan
described below.


*2. Spring and Fall releases each year*
Barring exceptional circumstances, starting with 2018, we plan to do at
least two feature releases of ParaView each year scheduled for March
(Spring) and September (Fall) with release candidates out in Feb and August
respectively.


*3. Patch releases as needed.*
Patch releases to fix critical issues with the Spring and Fall releases
will be cut as needed.


*4. Preview releases as needed.*
Preview releases to advertise new features may be cut at other times. These
are to be treated as alpha releases intended to demonstrate a new feature
or capability.

Any comments, concerns, or suggestions are always welcome.

Thanks,
The ParaView Team

Re: [Paraview] How to run a python script in every interaction

[Utkarsh Ayachit]

For camera interaction, you can add an observer to
vtkCommand::[InteractionEvent|StartInteractionEvent|EndInteractionEvent]
fired by vtkRenderWindowInteractor.

e.g.
def callback(caller, event):
   print ("ineraction")
from paraview.vtk import vtkCommand
view = GetActiveView()
view.GetInteractor().AddObserver(vtkCommand.InteractionEvent, callback)


There's no event fired on "Apply", however. Another option is to
observe vtkCommand::StartEvent and/or vtkCommand::EndEvent on the view
itself. This is fired at start/end of each render. Since that happens
as a consequence of any interaction including moving camera or hitting
apply or advancing timestrep, that may be a reasonable approach.

You can use `vtkSMPropertyHelper(glyph,

Each pvserver rank trying to connect the same socket is the classic symptom

Re: [Paraview] [EXTERNAL] pvserver MPI issue

[Utkarsh Ayachit]

Are you sure you ParaView is built with MPI support enabled? If so, are you
sure you're using the correct mpirun executable that goes with the MPI
implementation you used to build ParaView?

Re: [Paraview] Saving as csv data

[Utkarsh Ayachit]

Teng,

In your attached VTK file, stress is a cell data i.e. associated with
each of the cells rather than the points. When you export data as CSV
you can only save points along with point data or cells data and not
both. If you want to save out stress associated with each of the
points, you can apply the "Cell Data To Point Data" filter first and
then save the result out.

Re: [Paraview] Hardware for local install

[Utkarsh Ayachit]

Keith,

There's no easy answer for this, I am afraid. It depends on the type of
data and kind of processing you intend to do. A few things to note:

1. most data processing is done on CPU.
2. rendering, including rendering of image volumes using volume rendering
techniques as well as surface/polygonal rendering uses GPU.

What is the type of data or kinds of processing you plan to do? Maybe that
can help weigh the scale in direction over the other.

Re: [Paraview] Animate Clip - Cue does not have domain or property set!

[Utkarsh Ayachit]

That's indeed a bug.  Here's a fix:
https://gitlab.kitware.com/paraview/paraview/merge_requests/1955

For your build of ParaView (assuming you are using 5.4), you can load the
adding XML as a plugin and then create the filter. The XML will override
the builtin definition for the proxy and hence will overcome the issue.

  Set the origin of the plane.

  
  


  Set the normal of the plane.  For many filters this also sets the side
  of the plane that is of interest.  The normal points towards the
  "outside" of the plane.

  
  


  Specify the offset to shift the origin along the direction of the normal by.

Re: [Paraview] Question about modify data in VTK files

[Utkarsh Ayachit]

You can do similar things simply using Python and numpy, instead of matlab.
Numpy is included in the Python distributed with ParaView, so you can use
it in pvpython or Python shell in the GUI to open csv [1] and process it
add appropriate before saving out.

When user selects variables, he's doing it on the "VolumeArrays"
property. Thus the selection is provided to the VTK filter via calling
the command specified on the "VolumeArrays" property. In the case of
the ExtractCTHParts files, this is done via `AddVolumeArrayName` and
`RemoveVolumeArrayNames` API.

There are many filters you can base this on. Here are a few examples:

1. 
https://gitlab.kitware.com/paraview/paraview/blob/master/ParaViewCore/ServerManager/SMApplication/Resources/filters.xml#L2026-2041

Here the arrays to list is determined by the "InputArrayDomain"
element defined on the InputProperty and fixed to cell data.

2. 
https://gitlab.kitware.com/paraview/paraview/blob/master/ParaViewCore/ServerManager/SMApplication/Resources/filters.xml#L13865-13881

Here the user can separately select which attribute he/she is
interested in using a separate "AttributeMode" property.

Re: [Paraview] Details of XML filter with lists of input arrays

[Utkarsh Ayachit]

Dennis,

Before I answer the question, I need to know what are you adding this
property on? Is this a filter or a reader? The difference is that for a
reader, the information about arrays available is provided by the reader
itself; while for filter, that information is obtained from its input.

   pgc104% DISPLAY=:0.0 glxinfo

2. What GPU do you have and which drivers? If it's NVidia with new
enough drivers that support EGL, an EGL-enabled build may be a good
way to circumvent x-server issues.

Re: [Paraview] Trouble running paraview 5.4.1 with client-server mode.

[Utkarsh Ayachit]

Zhen,

Seems like the pvserver process is segfaulting/aborting. When does it
happen, as soon as the client connects or after someone steps? It hard to
gauge what could be going on. Is it possible for you to do a "debug" build
of ParaView on your cluster and then run through gdb? If can get the
callstack for the crash, we will have some clues.

Re: [Paraview] ParaView GPU support (UNCLASSIFIED)

[Utkarsh Ayachit]

Simon,

The answer depends on whether you want to ParaView to use GPU for
rendering alone or also for computation e.g. contours. For former,
it's automatic via OpenGL. So long as your environment and/or your
build is set up such that ParaView picks up the OpenGL implementation
provided by your GPU drivers, you'll get GPU acceleration. For
GPU-accelerated algorithms, you have to enable VTK-m support at build
time and then enable CUDA support for VTM-m. Currently, you need
create special filters via the VTM-m plugin [1] to use accelerated
versions of common algorithms like contour. In future, this will be
automatic, and you will be able to simply use the generic filters.

Hope that helps.

I am tempted to second that. There's nothing in ParaView that checks
how many cores your node has, as a result if there's a cap, it's
coming from the MPI implementation itself.

Re: [Paraview] SelectInputVector attribute in the SurfaceLIC plugin

[Utkarsh Ayachit]

Lionel,

There's indeed a bug there. A temporary workaround is as follows:

LoadDistributedPlugin("SurfaceLIC", ns=globals())
Disconnect()
Connect()

A fix for the issue is here:
https://gitlab.kitware.com/paraview/paraview/merge_requests/1898
I'll have it merged in before the next release.

Re: [Paraview] SelectInputVector attribute in the SurfaceLIC plugin

[Utkarsh Ayachit]

Lionel,

Does your Python script load the plugin explcitly? Currently none of
the state files capture which plugins are loaded, you have to manually
load the plugin. You can use  the following to load the plugin in your
script before creating any of the proxies.

LoadDistributedPlugin("SurfaceLIC", ns=globals())

Re: [Paraview] Question about animation background size

[Utkarsh Ayachit]

Does your current window size and target image size for the animation
differ in aspect ratio? That's one reason why animation view may not
match your expectation. With ParaView 5.5, there will be a "Preview"
mode which allow you to set up your viz to match the target aspect
(see https://gitlab.kitware.com/paraview/paraview/merge_requests/1733).
With 5.4 and earlier, you can use "Tools | Lock View Size Custom" to
lock the view size to an aspect ratio matching your target resolution
and then zoom in/out as needed to ensure a better fit.

Re: [Paraview] Error message: Not supported on OpenGL ES when I launch Paraview

[Utkarsh Ayachit]

Can you try something out:
1. Download https://www.paraview.org/files/dependencies/mesa-opengl-win64.zip
2. Put all the dlls in the same location as paraview.exe (or in your
PATH) and then start ParaView

Does that work? This should use  software rendering via Mesa3D and
avoid any driver issues we may be running into.

Re: [Paraview] Rendering/Screenshot with "deep color" (REPOST)

[Utkarsh Ayachit]

Jonathan,

As far as I know, no such a setting is not available in ParaView
currently. It's not on our todo list. Feel free to report an issue at
`https://gitlab.kitware.com/paraview/paraview/issues` so that it can
be tackled in the future.

Re: [Paraview] 答复: Help: How to get multi screenshots in one picture from Paraview

[Utkarsh Ayachit]

Shudi,

Is this what you're looking for:
https://www.paraview.org/Wiki/Parameter_Study

If so, you may want to look at Chapter 12 in the ParaView Users
Guide[1]. It covers in the comparative views in more up-to-date
details.

Re: [Paraview] [vtkusers] SafeDownCast does not work properly

Maximilian,

That's not a reasonable expectation. Mesh **isa** vtkPolyData, and not
vice-versa. Look at docs for dynamic_cast in C++. In spirit, SafeDownCast
is essentially the same thing.
