Dan,

This is a known issue [1] with the Projected Tetrahedra volume
rendering algorithm on Mac.

Re: [Paraview] troubles with netCDF reader ?

[Aashish Chaudhary]

Hi Cynthia,

If you could modify the vtkNetCDFCFReader (
https://github.com/Kitware/VTK/blob/master/IO/NetCDF/vtkNetCDFCFReader.cxx) to
work with WRF formats, that would be an awesome addition. I know few folks
that can use this work. Unfortunately we do not have any direct funding to
accomplish this but we will be more than happy to guide or help a little if
needed.

Let us know and we can discuss more offline.

Thanks,

Re: [Paraview] troubles with netCDF reader ?

[Dan Lipsa]

Hi Cynthia,
It is possible to change the reader. You'll need to compile ParaView from
source. The class you need to change is vtkNetCDFCFReader.
Probably you'll need an extra parameter to the reader that would be the
time unit. The time unit read from the file should overides this parameter.

You could also submit your changes back to VTK (most readers in ParaView
are actually part of VTK). This seems like something other people might
need.

Dan

Andrew,

The officially supported version of Qt is 5.9, but you could use down
to Qt 5.6 if you wanted.

[Paraview] Paraview source and its associated qt version

[Andrew Nicholson]

Is there anywhere that highlights what version of qt should be used for
building from source? Current version of qt being 5.9 from its website. Is
paraview on this version yet or an older version.

[Paraview] Relation between magnitude and camera view angle in SaveScreenshot

[Gregory Zaccaro]

Hi Paraviewers,


I have a simple question regarding the screenshot saving feature within 
Paraview.


I wrote a python script that I run with pvbatch which basically :

1) Load a polydata

2) Create a render view

3) Set up the camera (position, focal point, view angle)

4) Take a screenshot with SaveScreenshot(file_name, renderView1, quality=100, 
magnification=magnification)


There is a correlation between the magnification and the allowed View Angle 
values, but I can't figure out what it is.


The scale changes a lot between 150 deg and 170 deg of View Angle if the 
magnification =1.
When magnification is superior to 1 (ex. 2), the scales doesn't change much 
between 150 and 170 deg of View Angle. Why ?


What did I miss to understand the relation between these two parameters ?

That is odd. I'm not sure what is going on exactly. Have you tried
running your script with pvpython?

Re: [Paraview] troubles with netCDF reader ?

[Hart, Cynthia Joyce - (cyndyb)]

Hello,

To make a long story short, this solution you used below, does not work well 
for the weather forecasting group here on my campus that I am working with.  Is 
there any possibility of obtaining the source code of the Paraview netCDF 
reader?  If I could edit that source code to accept the non- CF compliant WRF 
outputs, I could make use of Paraview in an automated script to create 
animations for our forecasters much, much more readily than manipulating netCDF 
file headers.  The data I’d sent to you was but a very small subset of the 
hundreds of netCDF files we’d need to change, every time we do a model run, and 
this is a process we’d like to actually automate daily.  I am unable to force 
the output to be compliant as it is created.  Can you help?

Sincerely,

Cynthia Hart

Cynthia,
It seems that the files you send us are not CF compliant.
The problem is that the Time dimension does not have a unit.


Here are some quotes from the CF Conventions document:
- The use of coordinate variables is required for all dimensions that 
correspond to one dimensional space or time coordinates.
- Variables representing time must always explicitly include the units 
attribute; there is no default value

So, to fix one of your files, I did:

1. ncdump ARAD4_test2.ncdf > ARAD4_test2_CF.txt

2. I added a new variable Time with the unit specified to the txt file.


float Time(Time) ;
Time:units = "minutes since 2016-07-29 12:00:00" ;

3.
I generated a new nc file:
ncgen ARAD4_test2_CF.txt -o  ARAD4_test2_CF.nc

This new file is read correctly by ParaView.

Best,
Dan

Folks –

I am struggling with using the netCDF reader, with a bunch of timeseries of WRF

best.  The researcher I am trying to assist is currently on vacation, and I’m 
trying to animate the output of his WRF model.

So!  I have been viewing some of the output using the built in reader in 
Paraview (the ‘generic and cf’ reader) and it works for some variables, not for 
others.  I am using NCO tools to extract some of the variables of interest into

[Paraview] Hiding all pipeline objects

[Amelia Launspach]

Hi everyone,

I'm trying to hide all pipeline objects on my view. My paraview.simple does
not have a "HideAll" so I'm not sure how to do this. The following methods
have not worked for me:

def HideAll(view=None):

"""Hide all pipeline sources in the given view.

If view is not specified, active view is used."""

if not view:

view = active_objects.view

controller = servermanager.ParaViewPipelineController()

controller.HideAll(view)


paraview.simple.HideAll()



Does anyone know how I could accomplish this?
Seems simple enough but nothing is working

Thanks,
Amy

[Paraview] Dynamic colouring of the geometry in the animation, of warped eigenmodes

[Juha Kortelainen]

Hello all,

Thank you, Cory and Ken, for your answers. The trick with the Calculator 
and WarpByVector filters was what I was originally looking for as a 
quick solution, but when I tried some examples with the Programmable 
filter, I found it a very useful way to implement filters for relatively 
simple and light data processing. Though, I still need to study more 
about the details to make my Programmable filter to really work for my case.


- Juha -



Juha,

As Cory said you can create a plugin to replicate this behavior, but I believe 
you can also get similar behavior through a collection of filters. Although 
this is a bit cumbersome, you can try the following steps:

1. Before applying the WarpByVector filter, add the Calculator filter to your data. Set the "Result 
Array Name" to "OriginalCoords" and the expression to simply "coords". This will 
capture the point coordinates before warping.
2. Apply WarpByVector to this calculator filter as you did before to the FEM 
data.
3. Apply another Calculator filter to the output of WarpByVector. This time, set the "Result Array 
Name" to "ActualDisplacement" and the expression to "coords-OriginalCoords". This 
will capture the actual displacement applied after the scale factor is used.
4. Color your data by the "ActualDispalcement" field.
5. Set up your animation of the "ScaleFactor" for the WarpByVector filter as 
you did before.

You should now see "dynamic" colors based on the magnitude of the actual 
displacement.

-Ken

Yes, with some work. Take a look at this blog post for the general
idea:https://blog.kitware.com/easy-customization-of-the-paraview-python-programmable-filter-property-panel/

Basically, you can create XML plugins based on the Programmable Filter that 
feature some properties, such as a scale factor. The scale factor property 
should be exposed in the animation controls. Within your Programmable Filter 
script, you can perform the scaling of the vector with that scale factor 
property value. There are many examples of Python scripts for the Programmable 
Filter in Section 13.3 the ParaView Guide to get you started.

HTH,
Cory

[Paraview] how to uninstall paraview

[Jose Javier Munoz Criollo]

Hi

I'm facing a problem in Fedora 26, it seems like my Paraview GUI (5.4) 
is very very slow, compared with previous versions. I usually do the 
installation from the Fedora repositories. Now I'm trying to built from 
source to see if I can fix this problem.


However, after the first try it didn't work. It built correctly but the 
problem persists. I would like to uninstall it and try with an older 
version. Typically I would use Fedora package manager to remove Paraview 
but in this case I'm not sure how to properly uninstall it.


Any help would be highly appreciated.

Regards

Re: [Paraview] Get value of a vtkintarray object by the filed name

[Shayan Nikoohemat]

Hi David,

Thanks for the reply, it works now, but I can't see the original RGB colors
in renderview. In color map editor, I changed the settings to RGB but still
the color scale is scaled based on color pallet. Is there any other
settings that I missed?

Thanks.

Re: [Paraview] Get value of a vtkintarray object by the filed name

[David E DeMarle]

Try:

inRArray = ids.GetPointData().GetArray("R")
inGArray = ids.GetPointData().GetArray("G")
inBArray = ids.GetPointData().GetArray("B")  for x in range(0,
ids.GetNumberOfPoints()):
  rF = inRArray.GetValue(x)
  gF = inGArray.GetValue(x)
  bF = inBArray.GetValue(x)

[Paraview] Get value of a vtkintarray object by the filed name

[Shayan Nikoohemat]

I have a Paraview programmable filter written in python, that I am running
on a table of points to assign RGB colors as UnsignedCharArray. I'm just
stuck in one part of the code to get the value of R, G, B fields in the
range. Here is the table example:

[image: Inline image 1]

ids = self.GetInput()
ods = self.GetOutput()

ocolors = vtk.vtkUnsignedCharArray()
ocolors.SetName("colors")
ocolors.SetNumberOfComponents(3)
ocolors.SetNumberOfTuples(ids.GetNumberOfPoints())

inArray = ids.GetPointData().GetArray(0)for x in range(0,
ids.GetNumberOfPoints()):
  rF = inArray.GetValue(x) # here I need something like GetValue(x, "R")
  gF = inArray.GetValue(x) # here I need something like GetValue(x, "G")
  bF = inArray.GetValue(x) # here I need something like GetValue(x, "B")

  ocolors.SetTuple3(x, rF,gF,bF)

ods.GetPointData().AddArray(ocolors)

Can anyone help me to fix this.

The code source is from an old post from 2012.

Thanks.

Shayan
