Re: [Paraview] Visualize equdistant cell-centered data

[Cory Quammen]

Henrik,

I believe I understand what you are trying to do. However, there is nothing
available in ParaView to do this simply.

You could use the Programmable Filter to create a new structured grid with
the C+1 number of points in each dimension and then set the point data
array in the C-sized grid to be a cell data array in the (C+1)-sized grid.
The data layout is such that that should work. However, you will need to
set up the points manually.

Hope that helps,
Cory

You are right, the VTK XML file formats are quite capable; I would
avoid the legacy formats.

If you choose to ultimately write out to VTK XML files, I would skip
the intermediate file writing step.

Re: [Paraview] Scaling cylinder glyph's radius and height individually

[Cory Quammen]

Ahmad,

First, I recommend that you try loading your plugin in the ParaView
UI, using the ParaView that you built your plugin against. Then, in
Tools -> Manage Plugins. Click on Load New... and select the file
libvtkPVGlyphFilterP.so. You should now be able to find your filter
GlyphP in the Filters menu.

Second, to instantiate the filter the way you are trying is correct,
but first you need to load the plugin. I believe you can do it this
way:

vtkSMPluginManager::LoadLocalPlugin("//libvtkPVGlyphFilterP.so");

HTH,
Cory

I don't foresee any showstoppers. To make scripting easier, use the
Python tracing capability within the ParaView GUI. Tools menu -> Start
Trace, then perform the suggested actions. When done, choose Tools ->
Stop Trace, and you will see a dialog with the generated script that
you can use as a starting point.

Ah, I assumed your data was on a regular grid. I've modified the
example to set up a vtkPolyData instead to hold an unstructured set of
points. I have also shown how to add multiple arrays to the data set.
Just treat each scalar column you have as an array.

 import the simple module from the paraview
from paraview.simple import *
 disable automatic camera reset on 'Show'
paraview.simple._DisableFirstRenderCameraReset()

# Create a 2D image data object
from paraview import vtk
vtk_poly_data = vtk.vtkPolyData()
points = vtk.vtkPoints()
points.SetNumberOfPoints(200)
vtk_poly_data.SetPoints(points)

# Wrap data in numpy interface
from vtk.numpy_interface import dataset_adapter as dsa
poly_data = dsa.WrapDataObject(vtk_poly_data)

# Create numpy array. Set your data here
import numpy as np
x_coords = np.zeros(200) # zeros is just a stand-in for your actual data
y_coords = np.ones(200)
z_coords = np.zeros(200)

poly_data.Points[:,0] = x_coords
poly_data.Points[:,1] = y_coords
poly_data.Points[:,2] = z_coords

# Set the data in the image object
scalar1 = np.random.rand(200)
poly_data.PointData.append(scalar1, 'scalar1')
scalar2 = np.random.rand(200)
poly_data.PointData.append(scalar2, 'scalar2')

# Now set up a ParaView proxy for the image data
tp = PVTrivialProducer()
tp.GetClientSideObject().SetOutput(vtk_poly_data)
Show(tp)


# Set up filters, display options, etc. below

No, there is no ParaView-provided way to do that. Maybe there is some
other way you can do that with a different Python module. Note,
though, that ParaView does not provide a Python module manager a la
pip, so consider doing that experimental.

Hi Jens,

I was not able to reproduce the missing data in the bottom render view.

As for the legend size changing, I explained it and how to fix it in
your issue https://gitlab.kitware.com/paraview/paraview/issues/17938

Re: [Paraview] Can I generate a single file that contains data and filter settings?

[Cory Quammen]

Wyatt,

Here's a simple script that sets up a 200 x 200 image data object like
you might use for displaying a heat map.

 import the simple module from the paraview
from paraview.simple import *
 disable automatic camera reset on 'Show'
paraview.simple._DisableFirstRenderCameraReset()

# Create a 2D image data object
from paraview import vtk
vtk_image = vtk.vtkImageData()
vtk_image.SetDimensions(200, 200, 1) # Your size may vary

# Wrap data in numpy interface
from vtk.numpy_interface import dataset_adapter as dsa
image = dsa.WrapDataObject(vtk_image)

# Create numpy array. Set your data here
import numpy as np
arr = np.zeros(200*200)

# Set the data in the image object
image.PointData.append(arr, 'myarray')

# Now set up a ParaView proxy for the image data
tp = PVTrivialProducer()
tp.GetClientSideObject().SetOutput(vtk_image)
Show(tp)


# Set up filters, display options, etc. below


You can modify it as needed to set up your data array as a numpy array.

Hope that helps,
Cory

Re: [Paraview] Unexpected measurement appears in 5.4.1 but not 5.0.1

[Cory Quammen]

Hmm, that's weird. The Polar Axes should be off by default. Do the
Polar Axes appear when creating a Sphere source?

You should be able to force it off by adding the following line to the
loadFile() function in your script:

display.PolarAxes.Visibility = 0

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

The axes are tied to the physical extent of the data, as you have
observed, not the scalar range of the array mapped to Z. You can edit
the Data Axes Grid "Z Axis Label Properties" and enable "Z Axis Use
Custom Labels" to manually set the label values to those of your data
array. It is not automatically tied to the scalar array range, though,
but the Z labels will be independent of changes to the warp scale
factor.

I have encountered the same problem with the interpreter version
differing from the library version while having a homebrew Python
installed on my system. Perhaps there is an opportunity for a bug fix
in CMake's FindPythonInterp.cmake and FindPythonLibs.cmake files.

For now, what you have done is a reasonable workaround.

As a happy coincidence, Will Schroeder just posted a merge request for
a VTK filter that computes the volumes of connected regions in a poly
data and stores the volumes in field data:
https://gitlab.kitware.com/vtk/vtk/merge_requests/3825. We could
expose this in ParaView once it lands in VTK.

I'm hesitant to add an option in the Connectivity filter to do this.
Instead, I can imagine uses for a volume computation for
surfaces/volumes labeled by a RegionId that isn't necessarily assigned
as a function of connectivity. Instead, I would prefer to create a
separate filter that computes volumes for each RegionId in the input
dataset. You would feed the output of the Connectivity filter to this
new filter and get the volume-per-region information you want.

Right. Unfortunately, implementing my suggestion would require creating a
subclass of vtkPVGlyphFilter and importing that with a ParaView plugin. See
the ParaView Howto on how to add a filter to ParaView.

Yes, that should do it. Your modified glyph class will be available once
you've imported the ParaView plugin mentioned above.

A quick question about setting the active normals. Is there an existing way

I think that should work.

Re: [Paraview] xml keywords

[Cory Quammen]

Felipe,

Unfortunately, there is no one place that documents all the XML
elements and attributes. There is some documentation on property
attributes in [1], but I'm not sure this is an exhaustive list. Your
user is doing one of the most effective things already, looking for
desired functionality in an existing source/filter and looking at how
it is done in the .xml files.

Digging deeper, one can view the code in the methods ReadXMLAttributes
in the various vtkSM*Proxy classes in ParaView, e.g.,
vtkSMProxy::ReadXMLAttributes [2]., to understand which attributes are
available in different proxies.

Hope that helps,
Cory

Re: [Paraview] Compile Error of Paraview on Maverick

[Cory Quammen]

Ah, I see.

Make sure the same compiler module is loaded when you compile pvserver
as when you run it. That should ensure a consistent glibc version.

Your local user support or system administrators should also be able
to help with the module system usage on Maverick.

Thanks,
Cory

Re: [Paraview] Compile Error of Paraview on Maverick

Sorry, I was thinking you were building on a Mac with Mavericks
installed, but now I think that is not right. Are you trying to build
on Maverick Meerkat (Ubuntu 10.10)?

Re: [Paraview] error when compiling Paraview 5.4 macOS 10.13

[Cory Quammen]

Alas, this fix was made after ParaView 5.2 was released.

If you really need ParaView 5.2 instead of 5.3 or 5.4.1, you can apply
the patch in my previous email to the VTK subdirectory in the ParaView
source code. As you can see, just two lines need to be modified, so
you could easily do this manually.

Hope that helps,
Cory

Re: [Paraview] Compile Error of Paraview on Maverick

I don't see any errors in the terminal output you've posted. Are there
errors further back in the terminal output history?

Re: [Paraview] Glyph type options

[Cory Quammen]

Replying back to the list so that others may benefit from and
contribute to the conversation.

Rotate is an advanced property. To show advanced properties, look in
the Properties panel. Click the gear icon to the right of the text box
that says "Search ...". You can also search for "Rotate" in that text
box.

Re: [Paraview] Given 2D Displacement Field, Visualize Stretch as Geometric Change in Mesh

[Cory Quammen]

Charlie,

You can use the Warp by Vector filter to warp the points in your data
set according to a vector field. To get that vector field from your
p_x and p_y scalar arrays, it is convenient to use the Python
Calculator with the expression

make_vector(p_x, p_y, np.zeros(p_x.shape))

Apply the Python Calculator filter to your data set, then add a Warp
by Vector filter off the Python Calculator filter. Set the Vectors
property to "result", the default name of the array produced by the
Python Calculator.

Hope that helps,
Cory

Reduce the value of the "Scale Factor" property in the Glyph filter to
reduce the glyph size.

Re: [Paraview] Scaling cylinder glyph's radius and height individually

[Cory Quammen]

Hi Ahmad,

Alas, reading the code of vtkGlyph3D, you cannot orient by a vector
array different from the vector array used to do the scaling using the
functionality in ParaView. You would have to modify either
vtkPVGlyphFilter or its parent class vtkGlyph3D, to do this, and
expose the new VTK class through a ParaView plugin [1]. A simple
modification would be to add a ScaleMode, say VTK_SCALE_BY_NORMAL, to
vtkGlyph3D, and then set the active normals in your data set to the
vector by which you wish to scale. Then the "vectors" property could
control the orientation and the active normals would control the
scale. That's kind of kludgey, but it would be a fairly fast
modification to make.

HTH,
Cory

Re: [Paraview] error when compiling Paraview 5.4 macOS 10.13

[Cory Quammen]

Sergio,

This problem was fixed in November 2016, so I am surprised you are
running into it. Current ParaView master includes VTK that contains
the commit

commit 33631146a85dfa64433c3997f166cbaa96bedee9
Author: gnzlbg <gonzalob...@gmail.com>
Date:   Wed Nov 23 05:29:14 2016 -0500

[bugfix] Invalid pointer comparisons.

The code was performing a null pointer check
using (void*)Data <= 0 instead of Data == NULL
(or nullptr). This results in a compilation
error with clang trunk (future clang 4.0).

Make sure you have run `git submodule update` to ensure your VTK is up to date.

Re: [Paraview] Question about build paraview

[Cory Quammen]

It's kind of a quirk of CMake, but once CMAKE_CXX_COMPILER is set by
the initial CMake configuration, you can't change it. So what should
you do?

The solution is to set an environment variable named
CMAKE_CXX_COMPILER in your shell prior to running CMake for the first
time. Set that variable to the path of version of gcc or icc you want
to use, and that should do it. You may also need to set
CMAKE_C_COMPILER as well.

HTH,
Cory

Re: [Paraview] getting Client Info

[Cory Quammen]

On my Mac, I can copy individual cells, but not the whole table.

It would be a nice feature. Feel free to write up a feature request in the
issue tracker: gitlab.kitware.com/paraview/paraview/issues

Re: [Paraview] paraview GUI entry point not found in win10, compiled with qt 5.10 and vs 2017.

[Cory Quammen]

Check your PATH environment variable to make sure nothing is inserting a
path Qt DLLs different from the Qt with which you built ParaView. Note that
CMake installs Qt DLLs, so if you have that installed, your PATH may be set
to point to those DLLs.

Re: [Paraview] Color bar labels

[Cory Quammen]

Hi Quentin,

In the refactor of the color bar, we decided to replace the unreliable
"number of labels" option with a list of explicit labels you can set. The
number of labels option was only a maximum number of labels and often
didn't give you the requested number. To use the new list option, turn on
the "Use Custom Labels" checkbox in the "Edit Color Legend Properties"
dialog. The list lets you control exactly how many labels to provide, with
the caveat that you need to specify the label values manually. In addition,
there is no prevention of overlapping labels when this option is enabled.

I hope that helps,
Cory

Re: [Paraview] BUG REPORT: Axes grid option grayed out, version 5.4.1 64bit, on Ubuntu 16.04

Hmm, that's strange. Can you give step-by-step directions on how to make
the buttons grayed out, preferably with a simple starting source such as
the Sphere source or Wavelet source?

Re: [Paraview] loading multiple state-files without hiding and resetting already loaded objects

Hi Roman,

Sorry I failed to follow up. Did you find a solution to this problem?

This line in your script looks funny to me:

d[props] = pvs.GetProperty(repr, props[0])

Shouldn't props[0] just be props?

Re: [Paraview] How to read the file info in *pvd file

[Cory Quammen]

Did you make progress on this? You should just be able to use your
favorite Python XML module to locate all the  elements and
find the "file" attributes to get the *pvtu file names. Then you can
parse those *pvtu XML files to get whatever information you want. One
such module is documented here:
https://docs.python.org/2/library/xml.etree.elementtree.html.

HTH,
Cory

Re: [Paraview] background color not saved in state

[Cory Quammen]

Hmm, I can't reproduce with the following:

* Start ParaView
* Add Wavelet
* Change background color.
* Save state, reset the session, and reload the state.

Can you give step-by-step instructions for how to reproduce?

By the way, if you wish to discuss in the issue tracker, the original
Mantis issue has been copied to GitLab:
https://gitlab.kitware.com/paraview/paraview/issues/8722

Re: [Paraview] unable to RGB voxel from tiff/jpeg slice to volume

I'm not sure what you are referring when you say IsoVolume. Is this
the Contour filter in ParaView? If so, the Contour filter does not
operate on RGB data. The Threshold filter does not work with RGB data,
either. You may be able to instead use Find Data to locate all points
that fall in some range, and you can use a Python expression to
perform a union of thresholds on different channels. After you have
created a selection this way, you can extract the selection with the
Extract Selection button on the bottom of the Find Data dialog.

Note that image data is associated with points in images in ParaView,
not cells, so if you want to extract a selection of cells, you might
use the Point Data to Cell Data filter before creating a selection.

HTH,
Cory

Re: [Paraview] unable to RGB voxel from tiff/jpeg slice to volume

[Cory Quammen]

Joe,

This is more of a question for the ITK discussion forum [1], but I'll
give you a potential solution here.

The problem is that

typedef itk::Image  ImageType;

declares a 3-dimensional scalar-valued image, not a 3-component (RGB)
2-dimensional image. To declare an RGB ITK image, try this:

typedef itk::RGBPixel< unsigned char > RGBPixelType;
typedef itk::Image< RGBPixelType, 3 > ImageType;

I hope that helps.

Cory

Re: [Paraview] [EXTERNAL] Re: boolean mesh filtering

[Cory Quammen]

Alan,

It would be possible to expose the boolean operations filter in ParaView
without much trouble. However, that filter is limited to
polydata-to-polydata intersection (a plus for Jeff's application), and
works best when the geometries overlap but do not share faces (a minus for
Jeff's application). For Jeff's needs, I don't think it would be that
useful.

Thanks,
Cory

Re: [Paraview] Displaying volume outside of mesh as solid

[Cory Quammen]

There isn't anything in ParaView to view empty volumes. At some stage, the
volume you are talking about needs to be represented by a grid or mesh for
it to be visualized with ParaView. If you can generate a volumetric mesh
outside of ParaView, then you could use all the visualization techniques in
ParaView that apply to volume meshes. As a post-processing application,
ParaView has essentially no built-in functions for generating volume meshes.

Hope that helps,
Cory

Re: [Paraview] How to plot pressure map on an airfoil or circle?

[Cory Quammen]

Hi Eman,

The Warp By Scalar filter will warp a geometry, such as a circle, according
to a scalar field at each point in the geometry. The geometry must have a
Normals array set for this to work.

The Glyph filter can draw arrows scaled according to the scalar value at
your circular geometry.

HTH,
Cory

Re: [Paraview] [EXTERNAL] Re: pvbatch

[Cory Quammen]

Alan,

You should be able to run

pvpython --force-offscreen-rendering script.py

and no render window will appear. The help for --force-offscreen-rendering
says:

  "If supported by the build and platform, create headless (offscreen)
render windows for rendering results."

I believe this should work on linux systems, but you should try it out on
the system on which you want to force offscreen rendering just to be sure
before using it to produce classified images.

pvbatch running the same script will indeed not pop up a render window even
without the --force-offscreen-rendering option.

Let us know how it goes,
Cory

Re: [Paraview] vtkCutter

[Cory Quammen]

Hmm, vtkContourTriangulator may not copy point data to its output. You can
use Resample With Dataset to get the point data back in the output of
vtkContourTriangulator. Select the input to the triangulator as well as the
triangulator itself and add a Resample With Dataset Set filter. Set the
Input of this filter to the input of the triangulator filter, and set the
Source to the triangulator filter itself.

Re: [Paraview] vtkCutter

[Cory Quammen]

There isn't a filter exposed in ParaView to do this. You could expose
vtkContourTriangulator in an XML plugin [1] and apply that to the polyline
created by the planar Slice through your polygonal geometry.

You should change 'array_name' to 'MetaImage'. Sorry I didn't make it clear
that 'array_name' is just a placeholder for whatever name your array has.

ParaView 5.2.0 does have a "Rescale" color map feature. It is circled in

It's a bit complicated to select them in the user interface, but it is
possible. There was a related discussion on the mailing list recently on
how to do this: http://paraview.markmail.org/thread/j4ynkclxcucpqoa5

In the worst case, you can hard-code the array names if they don't change.
Relying on the active scalar attribute is old-style VTK and may go away
someday in the not-too-near future. Or you could just keep your original
code for defining array B.

To debug, I suggest writing your Programmable Filter script a few lines at
a time to determine which line causes the crash.

For that case, nothing comes to mind that will let you stored several
different vtkImageData objects in a single file. Even if a
vtkMultiBlockDataSet worked for your other needs, it would actually be
saved out as one .vti file for each block plus a top-level .vtm file that
points to the .vti files.

Sorry,

Re: [Paraview] Is it possible to group vtkImageData objects?

[Cory Quammen]

Hi Jimmy,

Try "Append Attributes". This will yield a single vtkImageData that has
several point data arrays, or "attributes". As long as the input
vtkImageData have the same dimensions, this filter will do what you like.
You can then pick which array you want to view with the Volume
representation.

To extract a vtkImageData with one or a subset of the appended arrays, you
can use "Extract Component" or "Pass Arrays", respectively.

HTH,
Cory

Re: [Paraview] Problem compiling ParaView with NMake

[Cory Quammen]

Hi Thomas,

I strongly recommend using the Ninja generator for building ParaView with
Superbuild on Windows. It will build much faster than if you use other
build generators, and will take care of the particular problem you are
seeing as -j is a Ninja option that controls the level of build parallelism.

Cheers,
Cory

Re: [Paraview] Programmable filter VTK/numpy

[Cory Quammen]

Hi Edo,

Documentation for the VTK/Numpy adapter can be found here:

https://www.paraview.org/ParaView/Doc/Nightly/www/py-doc/paraview.vtk.numpy_interface.html?highlight=numpy_interface#numpy-interface-package

You will likely be interested in the dataset_adapter module that provides a
convenient way to wrap VTK data objects in a Python class that provides
easy read/write access to VTK data arrays as Numpy arrays.

You could simplify your code quite a bit using this adapter as in the
following:

import numpy

from vtk.util import numpy_support, vtkImageImportFromArray

import vtk.numpy_interface.dataset_adapter as dsa


inData = dsa.WrapDataObject(inputs[0])

B = inData.PointData['array_name'] # best practice is to name the array


#B = numpy_support.vtk_to_numpy(

#inputs[0].GetPointData().GetScalars())


ifLarger = lambda x,M: x if x<=M else 0

fgt = numpy.frompyfunc(ifLarger,2,1)

#A = fgt(B,int(2**16*0.8))


ifSmaller = lambda x,M: x if x>M else 0

flt = numpy.frompyfunc(ifSmaller,2,1)

#A = flt(B,int(2**16*0.3))


ifBetween = lambda x,m,M: ifSmaller(x,m) if x<=M else 0

fbetw = numpy.frompyfunc(ifBetween,3,1)


A = fbetw(B,int(2**16*0.3), int(2**16*0.95))


outData = dsa.WrapDataObject(output)

outData.PointData.append(A,'new_array_name')


#A = numpy.asarray(A,dtype=uint16)

#dims = inputs[0].GetDimensions()

#A = numpy.reshape(A, (dims[2],dims[1],dims[0]), order='C')

#A = numpy.ascontiguousarray(A)

#importer = vtkImageImportFromArray.vtkImageImportFromArray()

#importer.SetArray(A)

#importer.SetDataSpacing(inputs[0].GetSpacing())

#importer.SetDataOrigin(inputs[0].GetOrigin())

#importer.Update()


#output.DeepCopy(importer.GetOutput())


Hope that helps,

Cory

Re: [Paraview] simple Programmable Source

Randy,

Try setting a name on the array with

scalars.SetName('array_name')

This should let you select this array as the color array in ParaView.

Felipe,

I can confirm this behavior, and I have filed a bug report here:

If it stops responding consistently after a specific event or sequence of
events, please let us know. It shouldn't do that :-)

I suspect that you do not have any cells in your 3-point data.vtk file.
Without cells, there is nothing for ParaView to visualize. This is a common
stumbling block for people trying to visualize point data.I suggest after
loading your data applying a Glyph filter. It should show you three spheres
colored according to your resistivity array. Now you should be able to
apply the Threshold and Slice filters as you would expect.

Cory

The message is a warning from the Qt side. Aside from being annoying,
it should be harmless. Sorry, but we haven't figured out why this
appears on some systems and not others.

Does it stop responding or does it crash? It's probably not related to
the warning message above.

Yes, that is correct.

That will work. Otherwise they would need to deploy Microsoft's MPI

Re: [Paraview] [vtkusers] Paraview Error while reading .vts file

[Cory Quammen]

Hi Siming,

Please reply-all to keep the discussion on the list so others may
participate and benefit.

This line in your export code is a problem:

sgrid->GetCellData()->AddArray(probe->GetOutput()->GetPointData()->GetArray(i));

Point and cell data arrays have different lengths for structured
grids. The writer is apparently not catching this, but the reader is.

Re: [Paraview] Fwd: paraview.simple

[Cory Quammen]

Hmm, this is very odd. I don't know why libarpack would be loaded. It
looks like something is loading it and libarpack does not like the
libgfortran that ships with ParaView.

If you are familiar with gdb, could you run pvpython through gdb and
get a stack trace where libarpack is being loaded?

Thanks,
Cory

Setting the PYTHONPATH is not necessary to use pvpython. pvpython sets
up the necessary system paths within the Python executable so you
don't have to.

This command means "launch the paraview executable in my current
working directory". To use the paraview executable in your PATH,
remove the ./ and run

paraview

This will make sure the paraview found on your PATH is executed.

Again, when you run ./pvpython, it is looking for a pvpython
executable in the present working directory. Drop the ./ and it should
work.

This is strange. I don't see the same when I download ParaView 5.3 on
Ubuntu 16.04. I wonder if you are pulling in something by setting
PYTHONPATH? Try not setting PYTHONPATH (it isn't needed to use
pvpython) and see if that resolves the error.

Sure, you can, but it may be slow.

Could you define your subdomains in a regular grid structure with a
number of even divisions in X, Y, and Z? If so, you may be better off
creating a grid structure with your 200 subdomains and then use the
vtkCellLocator approach I outlined earlier in this thread.

Re: [Paraview] Input files

Hi,

Welcome to ParaView!

It sounds like you might find several items in ParaView's help menu useful:

* Getting Started with ParaView
* ParaView Tutorial
* ParaView Guide

If you have more specific questions about how to load your data,
please describe the kind of data you have. Is it points? Is it a
volumetric mesh? Etc.

Thanks,
Cory

Ah, I didn't read far enough up in your code to see how `reppro` is
defined. ListProperties() just gives you the names of the properties,
not a list or dictionary with the values. You can create a dictionary
of properties and their values with

d = {}
for p in s.ListProperties():
  d[p] = GetProperty(s, p)
reppro.append(d)

Put a ** in front of reppro[i], e.g.,

pvs.SetProperties(repr, **reppro[i])

That works for me. The ** unpacks the dictionary into a variable
keyword parameter. See [1] for more info.

No problem.

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

[Cory Quammen]

Not seeing anything with Qt is a good thing in that it means some
other software installed on your system is not interfering with
ParaView's operation. That bad news is that I'm out of ideas on what
might be causing your problem.

Maybe a graphics card driver update would help?

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

[Cory Quammen]

Antonio,

No worries! We do run into issues from time to time on other Windows
machines, so we are happy to help you work through the kinks so that
we can understand the potential issues out there.

One other thing to look for:

 See if you have a different Qt installation on your system whose path
is in your PATH environment variable. To check, click on the
Start/Windows menu. Type in "environment" and select "Edit the system
environment variables". In the System Properties dialog that shows up,
click on the "Environment Variables..." button on the bottom right.
This brings up an Environment Variables dialog with user variables in
the top panel and system variables in the bottom panel. Look at the
Path variables and see if there is a location listed with "Qt" in the
name, or if you have a program that might use its own Qt.

Also look to see if an environment variable named QT_PLUGIN_PATH is
set. If it is set, it will confuse ParaView as it loads Qt and it
might result in this error. We have seen this in one other Windows
machine.

Best regards,
Cory

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

[Cory Quammen]

Antonio,

Do you happen to have an integrated graphics chip on your laptop? I
wonder if ParaView is set to use integrated graphics rather than your
NVIDIA card and isn't liking what it finds. You can try going to the
NVIDIA control panel. Under 3D Settings in the panel on the left,
click on "Manage 3D settings". On the right side, click on the "Global
Settings" tab. Make sure "High-performance NVIDIA processor" is
selected. Apply the changes, then run ParaView again to see if the
problem is resolved.

Re: [Paraview] loading multiple state-files without hiding and resetting already loaded objects

[Cory Quammen]

Hi Roman,

It turns out ParaView was not designed for this use case because of
certain difficulties discussed here:

https://gitlab.kitware.com/paraview/paraview/issues/17442

In your Python script, you could manually cash all the properties of
the existing representations and restore them after loading the most
recent state file.

The functions

reprs = GetRepresentations()
repr = reprs.values()[0]
props = repr.ListProperties()
GetProperty(repr, props[0])

would be helpful for this.

Cory

Re: [Paraview] vtkClipDataSet in a programmable filter

[Cory Quammen]

Xavier,

The runtime error is troubling. I suspect there may be a problem or
incompatibility with a shared library on your system.

If you wanted to debug further, you could try downloading Dependency Walker
[1] and load paraview.exe with it. It should show you the DLLs ParaView is
trying to load. I wonder if ParaView is trying to load a Python other than
the one it ships with?

HTH,
Cory

Re: [Paraview] Fwd: paraview.simple

[Cory Quammen]

> I usually use:
> ./

I think you would be better off running your script with

./pvpython 

pvpython comes with the ParaView binary and is located in the same
directory as the 'paraview' executable. pvpython uses the same Python
as ParaView is, so compatibility with some local Python on your system
is not a problem. Further, pvpython sets up Python environment to
provide access to the ParaView and VTK Python modules without having
to set up any environment variables.

python3 definitely won't work with the official ParaView binaries,
which are built against Python 2.7.

Re: [Paraview] Subdomain

[Cory Quammen]

Muhammad ,

You can try the Clip filter to generate box-shaped subdomains.
Counting the number of particles in each cell is a little more
complicated. Off the top of my head, I can't think of a filter that
does that for you. But, you could write a Programmable Filter that
does this. Briefly, the Programmable Filter would:

1. Set up a vtkCellLocator and give it the input to the Programmable
Filter (which is assumed to be a subdomain you've created with the
Clip filter)

2. Create a cell vtkDataArray (e.g., vtkIntArray) to store the counts
of particles falling inside each cell. The array should have the same
number of tuples as cells in the subdomain.

3. Iterate through all the points in a second input given to the
Programmable Filter. For each point, find the cell containing the
point using vtkCellLocator::FindCell(). Increment the count in the
cell array you created in step 2 given the cell ID returned by the
vtkCellLocator::FindCell() method.

There is a lot of information about the Programmable Filter in the
ParaView Guide and at
https://www.paraview.org/Wiki/Python_Programmable_Filter.

Hope that helps,
Cory

Re: [Paraview] vtkClipDataSet in a programmable filter

[Cory Quammen]

This works for me in 5.4.1:

import vtk

plane = vtk.vtkPlane()
plane.SetOrigin(0, 0, 0)
plane.SetNormal(0, 1, 0)

clip = vtk.vtkClipDataSet()
clip.SetClipFunction(plane)
clip.SetInputData(self.GetInput())
clip.Update()

self.GetOutput().DeepCopy(clip.GetOutput())

Make sure you set the "Output Data Set Type" to "vtkUnstructuredGrid"
before you first hit Apply. I believe there is a bug that does not let
you change the output data set type after you first click Apply.

HTH,
Cory

Re: [Paraview] paraview.simple

[Cory Quammen]

Guillermo,

I'm sorry that my suggestions didn't work out.

Could you try one last thing? Please run the following commands:

cd /opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin
./paraview

That should work without problem. If it doesn't, we definitely have a problem.

Cheers,
Cory

Re: [Paraview] paraview.simple

[Cory Quammen]

Oops, I failed to change the version number in the line I gave you,
but caught that and corrected it, just not quite to the right version
number.

Try

export 
PYTHONPATH=$PYTHONPATH:/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/paraview-5.3

Basically, you have to set the PYTHONPATH to where the lib*Python.so
files are located. Make sure
/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/paraview-5.3
exists and confirm that a file starting with libvtkCommonCorePython27
is there.

Stepping back a bit, you wouldn't have to do any of this PYTHONPATH
stuff if you just add

/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin

to your PATH.

HTH,
Cory

Guillermo,

Please CC the mailing list so others can participate and learn from
the discussion.

That looks like progress. Now try adding to your .bashrc:

export 
PYTHONPATH=$PYTHONPATH:/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/paraview-5.4

[Paraview] ParaView 5.4.1 is now available for download

[Cory Quammen]

The ParaView development team is pleased to announce that ParaView
5.4.1 is available for download. Binaries and source code are
available from

www.paraview.org/download

Note that the ParaView Download page has been updated with an improved
layout that makes downloading ParaView easier.

The ParaView 5.4.1 bug fix release addresses a number of problems in
5.4.0, including:

* The black render window observed on some systems when FXAA was
enabled or an object's opacity was less than 1 has been fixed.

* Field output for cells with non-straight edges has been corrected.

* Derivatives for quadratic triangles are now computed correctly.

* A bug that occurred when generating a Catalyst script with no images
output has been fixed.

* A problem with writing animations as AVIs was fixed.

* Logic in the CGNS reader was updated to correctly read all solution
nodes for each centering type when FlowSolutionPointers are missing.

* Fixed crash in CGNS reader when moving forward in time.

* Fixed problem with long-running animations not advancing past a
certain number of time steps.

* Resolved issue where changing one file path in the state file loader
"Choose File Names" dialog also changed the file paths of other files
with the same type.

* Addressed problem with enumerated property dependencies in ParaViewWeb.

* Added ability to change the font size in the ParaView user interface.

* Fixed BoxLib3D file reader.

* State files now properly support files with relative paths.

* Removed inappropriate scalar bar scaling when saving large screen shots.

* A bug in the color mapping that in some cases incorrectly mapped
some data values to the above-range color was fixed.

* OSPRay can now be compiled in Cray programming environments and for
the first time has support for Intel Skylake processors.

 * Added lower limit to how small the GUI font size can be.

 * Addressed issue affecting layouts when loading a state file from
the Python console.

Thanks!

At the point of download? We don't list required versions on the
downloads page I'm afraid. We do list some of the dependent library
versions in the official binaries on this page:
https://www.paraview.org/Wiki/ParaView/Binaries

Qt version requirements are available in the source, though. See
Documentation/dev/build.md.

CMake will also tell you which version of Qt it finds when you
configure the ParaView build, and which Qt version is officially
recommended.
