Re: [Paraview] EXTERNAL: Re: ParaView in stereo with NVidia 3D Vision

[Jim.Eliot]

Hi Cory,

Building ParaView with VTK_REPORT_OPENGL_ERRORS makes the error message go 
away, but still no stereo. The image it plots looks like a regular non-stereo 
image.

Kind regards,
Jim

Hi Jim,

Considering the error message you are seeing, I wonder if setting the 
VTK_REPORT_OPENGL_ERRORS option to OFF might help.

Thanks,

Hello Jim,
Before spending too much time tracking this down as an error, and just to be 
sure, are you trying to do this with “3D Vision” or “3D Vision Pro”? The 
regular 3D Vision does not have OpenGL capabilities and so will not give you 
stereo. If you are using 3D Vision Pro, then I defer to the ParaView gurus…

Cheers,
Eric

Good afternoon everyone,

I have been trying to use ParaView in stereo using NVidia 3D Vision glasses but 
I am seeing an error. I am using ParaView version 4.3.1 on Linux built using 
Superbuild.

I have been launching ParaView as follows:

paraview --stereo --stereo-type=”Crystal Eyes”

When ParaView starts I see the following error message:

ERROR: In 
/build/paraview/src/paraview/VTK/Rendering/OpenGL/vtkOpenGLCamera.cxx, 
line 167
vtk OpenGLCamera (0x33c9940): failed after Render 1 OpenGL errors detected
  0 : (1282) Invalid operation

Is this a problem with how I am trying to use ParaView, or is it a bug? Is 
there anything that I can try to get stereo working?

Thanks,
Jim

[Paraview] Plot over Line source

[no name]

Hey there

I have some hundred VTU files and I want to plot some data in a graph (Plot
over Line - POL) next to it. The Problem is, the data from these POLs is
coming from a simple log file, basically conaining only x and y values
(like two np.arrays).

I can transform the arrays via

from vtk.util import numpy_support
values = np.array((x,y))
vtk_values = numpy_support.numpy_to_vtk(values, array_type=vtk.VTK_FLOAT)
vtk_values.setName('values_2_show')
vtk_values.setComponentName(1, 'x_value')
vtk_values.setComponentName(2, 'y_value')

But so far I have no success with how to change the input (source)

VTUFILE = FindSource('VTUFILE*')
plotOverLine1 = PlotOverLine(Input=VTUFILE, Source='High Resolution
Line Source')

to a simple array.

Thanks for any help!
Richard

[Paraview] The approach of Paraview's parallel rendering

[周恒众]

Hello everyone . Recently, I do some research about parallel rendering 
. I want to know how paraview do the parallel rendering . Does it use sort last 
or sort first ,or both .
I know it use IceT at last . If Icet is a sort last libaray , it should 
transfer the final pixel to the corresponding node , where  it do this . Or it 
is a sort first , so every node has all the datas ,and just render the datas 
corresponding to the screen .
Also ,i want to know if paraview achieve the loading balance ,and how 
does this?
who can tell me these ,thank you very much!

Re: [Paraview] [EXT] Re: How to find the nearest quad element?

[Dennis Conklin]

All,

So I have taken a shot at this and have a few questions.

I have multiple blocks of quads and I need to find the nearest quad for every 
hex in the model (also multiple blocks).  The purpose of this is to assign the 
Normal to the nearest quad to each hex

My approach was:

1.   Create 2 inputs for the Programmable Filter

a.  1st is regular Exodus file

b.  2nd is regular file with Extract Surface/Generate Surface Normals/Cell 
Centers filters run – this has no cells, only points at the quad centers that 
contain what I want, which is Normals to the quad (also contains points at the 
hex centers, which I will use later)

2.  In PF, I loop thru all quad blocks in the 2nd input and build 2 arrays. 
 First array has all the points in all the quad blocks in the 2nd input, and 
the second array has the corresponding normal associated with those points.

Now, I make a vtk.vtkKdTree and use BuildLocatorFromPoints(my pt array)
Now I loop over all hex in model, call FindClosestPoint using the point from 
the Cell Centers filter for the hex.  This returns an integer index and I 
assume Normals(index) is the normal associated with that quad

I do not get a sensible output.

My conclusion is that when I go thru this process, the index returned from 
FindClosestPoint is no longer synced to the original order of the points, which 
causes it to be a bad index into my Normals array.

It’s also extremely possible that there is some setup of kdTree that I need to 
do first that I am omitting.

So, is there a way to get kdTree to preserve the original order of the points, 
or is there another way to get an index back into my array of Normals, such 
that I can figure out which one is associated with the return from 
FindClosestPoint

I’m not sure this is clear enough to be interpreted by anyone, but here’s 
hoping.

Hi Dennis,

You might also be interested in the vtkCellCenters filter. As the name 
suggests, it
will generate the centers of the cells for you. If you are not in a big rush, I 
can build
you a small self contained sample in Python that demonstrates the filter and the
use of the point locator. I am a little busy at the moment, but I can post the 
sample
in a couple of days.

What about the following:

Generate two additional datasets, one containing (an approximate of) the center 
of the hex elements, the second the center of the quads. Then create a 
vtkKdTreePointLocator object based on the center points of the quad elements. 
Than loop over the centers of the hex elements and use one of the Find* methods 
to get the closest quad.

Sam,

Thanks for responding.  You have helped me several times in the past and I am 
always grateful for your insights.  In this case there is considerable 
refinement in the model, so only a very small portion of the hex elements are 
in immediate contact with quads.   Also you could think of places like the 
tread in the tire where there is no reinforcement whatsoever.

Another approach which I have considered is a wave propagation technique, where 
in the first wave every hex immediately adjacent to a quad gets direction 
cosines assigned (as you suggest).   Then you loop thru the remaining elements 
and assign cosines from any adjacent quad or hex that has cosines.   Eventually 
the direction cosines will propagate throughout the model.   A major 
complication is that wavefronts will collide and then you will have to choose 
which of several conflicting neighbor cosines

I am new to paraview and H5part file format. Can someone please guide me

Re: [Paraview] Add texture to obj files

Dear Cory. Thanks for the tip. I've tried, but there seems to be a problem,
as after trying what you suggested, the grid does not show the texture
correctly... it looks like a solid, black, color. Meshlab has no such
problems... still trying to figure this out.

Thanks again.

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

[David Trudgian]

Hi,

After working through the information on the web I've built Paraview 4.3.1 with 
OSMesa support, osmesa 10.5.4 with llvmpipe, and libGlu 9.0.0. MPI is OpenMPI 
1.8.3 and everything is compiled using the Intel 2015 compiler suite.

A Paraview build using MPI and standard OpenGL is working nicely on our GPU 
compute nodes with NVIDIA Tesla cards. However, if I start the OSMesa pvserver 
(for our non-GPU nodes) and connect from the client I immediately receive an 
error:

QWidget::repaint: Recursive repaint detected

The client will exit. The server doesn't exit, but is unresponsive to further 
connection attempts.

Has anyone else come across this issue with an OSMesa build? As above, the 
build using a physical NVIDIA card works great, with MPI working nicely etc.

Many Thanks,

be possible to get a callstack to when than error message is popped up?

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

[David Trudgian]

Hi,

Built a debug version. On the client side I now noticed the following warning 
on the console after I acknowledge the error dialog:

Generic Warning: In 
/home2/dtrudgian/paraview/ParaView-v4.3.1-source/VTK/Rendering/Parallel/vtkSynchronizedRenderers.cxx,
 line 730
Only 3 or 4 component images are handled.

The pvserver stack trace is below. I guess this is something to do with the 
OSMesa config?

Program received signal SIGSEGV, Segmentation fault.

Yes I do, and when I do this, I get a note from vrpn_server that
ParaView has connected, and when I hit stop, I get the note that the
connection was dropped. All what I would expect, except that ParaView
does not react to the input...

Niklas

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

[Utkarsh Ayachit]

Mind attaching the CMakeCache.txt from the server build? BTW, this is
totally different error than what we started with. The original issue was
that the client was complaining about recursive paint. Seems to me the
pvserver build is a little messed up right now.

Re: [Paraview] Plot over Line source

[Cory Quammen]

Hi Richard,

You won't be able to set a vtkDataArray subclass as the input to a
PlotOverLine filter. Instead, you should read the log files in a
Programmable Source, and connect the Programmable Source to the
PlotOverLine filter.

See Chapter 13 of the ParaView Guide [1].

Hope that helps,
Cory

Re: [Paraview] The approach of Paraview's parallel rendering

[David E DeMarle]

ParaView uses IceT and does sort last compositing. ParaView gives IceT
color and depth buffers from each node, IceT quickly gives us a depth
composited image.

There are exceptions, but in general we do not do anything special with
regards to load balancing. Rather, we read in the data in parallel and keep
whatever partitioning scheme the simulation code that produced it wrote it
in.

Thanks Ken. I do not see the checkbox. I am using the PV4.1.0 linux binary

[Paraview] Paraview 4.3.1, VR Plugin and VRPN

[Niklas Röber]

Hi,

I'm a little stuck. I was trying to connect our tracking system for a 
large VR wall with ParaView. The tracking runs fine with Avizo from Fei 
(using dtrack), but I wanted to use it for ParaView too. We have tracked 
glasses and a flystick for interaction. The communication of the 
tracking server via VRPN to the client PC works great, with


vrpn_print_devices DTrack@localhost -trackerstride 100

I can see the two sensors moving and all the buttons that are pressed. 
My tracking config file for ParaView is attached. When I start the 
tracking in ParaView, I see that ParaView connects to the started 
vrpn_server, and I also see a note if the connection is dropped. But 
thats all, I don't see any interaction or changes in my viewport. Am I 
doing something totally wrong? I also tried running it as client/server 
with the same effect of not working.


Thanks for your help!
Cheers from Hamburg ...
Niklas :)

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] PV 4.1 animating plot over line using global max/min

[Moreland, Kenneth]

Sorry. I missed the version you were using. The location of that option moved 
to where I described in ParaView 4.2.

In ParaView 4.1, that option is in a separate "View Settings" dialog box. To 
get that dialog box, click the button on the left of the thin toolbar directly 
above the plot view. In the navigation panel on the right, click Left Axis -> 
Layout and then select "Specify axis range explicitly"

Is there an option so that animating plot over line will use the global max/min 
values instead of the localo max/min values for each time step?
animating contours uses the global max/min values and I would like to do this 
with plot over line.
Hope my question is clear.

Your config looks correct to me. I am assuming that you hit start on the
ParaView UI panel to actually let ParaView use that data?

[Paraview] Programmable Filter with Multiple Inputs

[Dennis Conklin]

All,

I'm a little uncertain about Programmable Filters with multiple inputs.   I had 
been assuming that if I had 2 inputs, then inputs[0] is the input that's higher 
up in the Pipeline Browser, and inputs[1] is the lower input in the Pipeline 
Browser, but that does not always seem to be the case. Is there some way to 
invoke the PF in such a way that I can know which input will be which?

Thanks

Dennis

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

No idea ? No known python example / code snippet ?

How to extract one face from an hexa in python ?

I have an hexa read from an xmd file. In the ParaView GUI, I use the
ExtractSurface filter to get the skin of it. Then I select one face.
Then I use the ExtractSelection filter : I get the face extracted as 
I

need (without error message).

OK, now I need to do that with python scripting : if somebody has the
corresponding code snippet I'd appreciate to get it (filter creation
is OK. What I don't know is how to select a face from the hexa 
surface

in python). I activated "tools / start trace (+ general option : all
properties)" to get an idea of the python code. When I create the
ExtractSurface filter, I get :

This crash is maybe related to the ParaView build ? I run
Ubuntu-14.04, ParaView-4.3.1 has been built from source without any
specific / triky option (or some basic options like cmake
-DPARAVIEW_INSTALL_DEVELOPMENT_FILES:BOOL=ON
-DModule_vtkIOXdmf3:BOOL=ON) : do I have to turn on some option(s) at
build time to avoid the crash ? I attached the CMakeCache file.

Re: [Paraview] The approach of Paraview's parallel rendering

[周恒众]

Thank you!
I know the paraview have the D3 filter , If I don't use the D3 filter , Does 
the paraview use the Icet to sort last ? I find that all nodes need to know  
all the datas . In this situation , if sort-last, I think that every node  
don't need all the datas , why should this?

There are exceptions, but in general we do not do anything special with regards 
to load balancing. Rather, we read in the data in parallel and keep whatever 
partitioning scheme the simulation code that produced it wrote it in.

I know it use IceT at last . If Icet is a sort last libaray , it should 
transfer the final pixel to the corresponding node , where  it do this . Or it 
is a sort first , so every node has all the datas ,and just render the datas 
corresponding to the screen .
Also ,i want to know if paraview achieve the loading balance ,and how 
does this?
who can tell me these ,thank you very much!

Look at the paths in the output of:

>>> import sys
>>> sys.path

from pvpython. You may be missing some paths (there are 4 or 5 IIRC, but
the paraview.app packaging may reduce that).

OS X uses 'DYLD_LIBRARY_PATH', not 'LD_LIBRARY_PATH'. You should only
need to use the '/Applications/paraview.app/Contents/Libraries'[1] path
for this.

exists in the .app or not…

[Paraview] No module named paraview...

[Ruggiero Guida]

Hi


I am trying to run paraview scripts from the command line without using the
specific pvpython from paraview (this one works).


This is my setup:


Mac OS X 10.10.5

Paraview 4.3.1

Python 2.7.10 :: Anaconda 2.3.0 (x86_64)


I have tried several solutions that are supposed to work (but don't, at
 least for me) and ended up with the two env variable definitions in my
.bash_profile


export
PYTHONPATH="/Applications/paraview.app/Contents/Libraries:/Applications/paraview.app/Contents/Python/paraview:/Applications/paraview.app/Contents/Python/vtk:/Applications/paraview.app/Contents/Python/paraview"


export
LD_LIBRARY_PATH="/Applications/paraview.app/Contents/Libraries:/Applications/paraview.app/Contents/Python/paraview:/Applications/paraview.app/Contents/Python/vtk:/Applications/paraview.app/Contents/Python/paraview"


I have only 3 python installations in my system: anaconda, system python
and pvpython from paraview. All installed in default directories.


>From the python shell console is I run:


import os

os.environ


I do see the two variables `PYTHONPATH` and `LD_LIBRARY_PATH`.


Honestly I have no idea of what else to try. This seems to be a common
issue given the number of people that ask the same question. It also seems
not to be limited to paraview. Thanks

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

Hi Utkarsh,

Thanks a lot, I'll give it a try.

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] Read EnsightGold with different timesteps

[Braun Fabian]

Hi all,

As I haven't yet received a reaction onto my previously reported problem on 
crashing ParaView when reading EnsighGold *.case files (see email below) I 
would like to enquire again if no one has a solution to this problem or at 
least is aware of this as a known bug? 
I would be happy to share my EnsightGold files in order to solve this problem...

Additionally, I have another similar issue where I have again EnsightGold files 
which hold 5 time steps of a 3D surface mesh whereas for this mesh only the 
node coordinates but not the mesh connectivity do change over time 
("change_coords_only" option in .case file). Even though the ens_checker 
validates these files successfully, ParaView does not seem to be able to cope 
with this scenario. 
When loading the .case file the mesh of the first time step is visualized 
properly. However, when one changes the time to any of the following time steps 
no more mesh is visible and the statistics inspector reports 0 everywhere (No. 
of Cells/Points, Memory, etc.).

Any idea on how to tackle these two issues? 
(For me the first issue - in the email below - is the more interesting one)

Thanks a lot for your hints in advance!
Best wishes,
Fab

Subject: [Paraview] Read EnsightGold with different timesteps

Dear all,

In order to nicely visualize a dynamic 3D model I want to use ParaView in 
combination which EnsightGold (*.case) files. My tetrahedral FE model has a 
static geometry and only one variable of the elements (scalar per element) is 
changing over time.

To this end I created three files: (1) example.case, (2) example.geo, (3) 
example.sigma. The latter is holding all timesteps of the dynamic variable (in 
my case the conductivity).
Furthermore, I've verified these files using the ens_checker application which 
concludes with a positive "Hooray! Data format verification SUCCESSFUL with No 
Warnings".
However, if I load the casefile in ParaView only the first timestep can be 
visualized. As soon as I change the time to another timestep ParaView freezes 
(no more reaction and consumes 100% of CPU).

Is it possible that what I want to do using the EnsightGold files is not 
supported by ParaView?
What else would you suggest me to resolve this problem?

Thank you very much for your help in advance.
Best wishes,
Fab

PS: I am using ParaView 4.3.1 on a Win 7 64-bit machine
PS2: A hint which might be useful for others looking for the ens_checker 
application: I simply downloaded the current trial version of Ensight, opened 
the executable of the setup in an archive manager (e.g. 7-zip), located and 
extracted the ens_checker.exe.

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.

Utkarsh,

Ok, thanks for that information.   For my present case I can do some testing to 
determine which is which, but that limits how general purpose I can make a PF 
with multiple inputs.There is not always a reasonable test which is known 
ahead of time.
