Re: [Paraview] paraview quits when run through Windows Remote Desktop

[Andrew]

Sorry for small offtopic, but I didn't notice any remote access issues with
ParaView 5.0.1 RC2 on Windows 7 x64, but I use Linux client (FreeRDP 1.0.2).

[Paraview] Paraview ray tracing plugin | OSPray

[Raj Kumar Manna]

Dear All,

I came to know the ray tracing plugin for Paraview -OSPray. Is there any
documentation for this plugin, like we have one for Surface-LIC
? I can
load the plugin in my paraview 5.0 but could not figure out how to use it.

Thanks your help.
Raj

Re: [Paraview] [EXTERNAL] BadAlloc Error

[Andy Bauer]

Hi Lloyd,

If you've built ParaView yourself in the past then doing it with EGL
support shouldn't be any more difficult. The link that Utkarsh sent out
covers most if not all of the necessary information. I'll highlight the
fact though that you'll need to update your NVIDIA drivers to at least
355.11. The dashboard that's testing ParaView with EGL is running 358.13.

If you're building 5.0 or 5.0.1 it may not have the newest stuff for easily
finding EGL libraries. For reference, on our EGL dashboard machine the
location that the default NVIDIA driver install puts the EGL libraries and
header files are:
 EGL_INCLUDE_DIR  /usr/include
 EGL_LIBRARY  /usr/lib/x86_64-linux-gnu/libEGL.so
 EGL_gldispatch_LIBRARY
/usr/lib/x86_64-linux-gnu/libGLdispatch.so.0
 EGL_opengl_LIBRARY   /usr/lib/x86_64-linux-gnu/libOpenGL.so

Please let us know if you have any problems.

Best,
Andy

Re: [Paraview] paraview quits when run through Windows Remote Desktop

[Utkarsh Ayachit]

You cannot use ParaVIew 5.0 or later over remote desktop anymore.
ParaView now needs newer OpenGL (3.2 or later) and remote desktop uses
software OpenGL implementation that only supports OpenGL 1.1. It may
be possible to build Mesa3D (http://www.mesa3d.org/) on Windows, but I
personally don't have much experience with Mesa3D on Windows. Maybe
someone else can chime in.

Hi,

Paraview "started crashing" recently. It was because I switched to trying

Re: [Paraview] [EXTERNAL] BadAlloc Error

[Utkarsh Ayachit]

Lloyd,

For a headless server with K80s, you cannot use binaries distributed
from paraview.org. I'd suggesting building ParaView from source with
EGL support (refer to
https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/).

Andy, can you point Lloyd to any addition ParaVIew + EGL build
information that may be useful? Thanks

Utkarsh

[Paraview] ParaView 5.0 Python and Batch

[Scott, W Alan]

Question from a user:

Quick question, I'm looking through the documents and can't seem to find what I 
am looking for. I want to create a batch script to save an image every few 
seconds of my simulation. I'm aware of vtkAnimationPlayer, where I can use 
GetAnimationScene and use GoToNext() to get the next frame and perform 
SaveScreenShot inside a python loop. However, is there a method similar to 
GoTo(double time) ?? I don't want to load every time frame as it takes a long 
time to load each one. I would like to do it at a variable time interval inside 
a python loop. Obviously, I can loop through with GoToNext and save every 100 
frames etc, but that will take forever loading them up.

I tried doing a trace monitor, but it does not reflect an action taken where I 
type in a time inside the "Time" box. However, it does report when I press the 
animation buttons, ie. GoToNext, GoToFirst, GoToLast etc.

Please advise,

Re: [Paraview] EXTERNAL: Re: CxxOverlappingAMRExample with Catalyst Live

[Andy Bauer]

Hi Jim,

Yes, you can have a Catalyst instrumented code connect to something running
pvserver and have the pvserver connect to the client. At the end of the
Python generated scripts there should be a line that looks like:
coprocessor.DoLiveVisualization(datadescription, "localhost", 2)

Here you just have to edit it to point to something other than localhost.

As for overlapping structured grids, there's no convenient
composite/multiblock data set for that like there is for Cartesian grids.
What you would need to do is use vtkStructuredGrids with blanking done
manually and then just add them in as blocks in a vtkMultiBlockDataSet. It
won't have the structure that the AMR specific composite data sets have so
it may be a bit slower for some filters but it should work pretty much like
you want for most stuff. Please let us know if you try this out and get
unexpected/undesired behaviour.

Best,
Andy

One should not access data in RequestInformation. Data is not expected
to be available in this pass. It can work in certain cases where the
upstream was explicitly updated before the Programmable Filter was
created, but will not work always -- as you're seeing with your
segfaults when loading state file.

Re: [Paraview] [EXTERNAL] Save set-range-values

[Scott, W Alan]

Lukasz,
Not that I know of.  This really shouldn't be a setting - this should be 
default behavior.  Min/max shouldn't change for a variable as you explore your 
data.

I took the liberty of writing this bug up.  It is here: 
http://www.paraview.org/Bug/view.php?id=16052.  I also targeted it for the next 
release or two.

Thanks for reporting it.

Subject: [EXTERNAL] [Paraview] Save set-range-values

Dear All,

Is it possible to save the variable ranges in the set range box for a given 
variable just like the color map settings? Each time a variable is 
re-displayed, its value range is reset to min/max. I would like to set some 
range for a variable, let's say pressure, and have Paraview stick to these 
ranges each time this variable is displayed throughout the session.

Example:

Take disk_out_ref.ex2 and view velocity magnitude. Set ranges to min=10 and 
max=16, change coloring to temperature and then back to velocity magnitude. The 
previously defined ranges are reset to global min/max.

Regards,
Lukasz

[Paraview] Paraview crashes when loading a saved state file that includes a Programmable Filter with a specific line

[Evan Kao]

Paraview version: Paraview 5.0 on Windows 7 64-bit

Hello all,

I noticed a fairly specific issue and I was hoping if someone could
enlighten me as to why it happens.  In the RequestInformation section of a
Programmable Filter, I have the following line:

if inputs[0].VTKObject.GetCell(0).GetClassName() == 'vtkPolyLine':

i.e. I'm testing if one of the inputs has a polyline cell.  When I save the
state and reload it, Paraview crashes.  Through some testing, I found that
the issue is specifically with

inputs[0].VTKObject.GetCell(0)

There must be some nuance in the VTK/Paraview pipeline that I'm unaware of
that results in a memory issue or something when attempting to retrieve a
cell while loading a .pvsm state file.

The issue should be easily reproduced by creating a sphere, applying a
Programmable Filter, and simply typing inputs[0].VTKObject.GetCell(0) in
the Request Information box, saving the state and reloading it.

I can get around it, but I wanted to know why it happens to get a better
understanding of VTK or Paraview.

If you want to know the application: The filter takes in two inputs and
only one is time-dependent.  To keep the time-dependence, I needed to
figure out which input is the time-dependent one (the one that I know is
not a line) and set the time steps and time range of the output information
accordingly.

Thanks,
Evan Kao

Re: [Paraview] EXTERNAL: Re: CxxOverlappingAMRExample with Catalyst Live

[Jim.Eliot]

Hi Andy,

Thanks for your reply. Currently I am looking at the small examples but I would 
like to be able to fetch larger geometries in future. Is it possible for the 
simulation to connect to a parallel pvserver which will send images back to the 
client?

Putting interactive usage to one side for a moment, is non-uniform AMR 
supported in Catalyst batch? I.e. overlapping structured grids . I couldn’t 
find any references to non-uniform AMR in ParaView while researching.

Kind regards,
Jim

Subject: EXTERNAL: Re: [Paraview] CxxOverlappingAMRExample with Catalyst Live

Hi Jim,
Yes, currently Overlapping AMR data sets are not supported by Catalyst Live. 
This is because VTK doesn't support sending that data object. That would have 
to be changed in vtkCommunicator::Send(vtkDataObject* data, int remoteHandle, 
int tag).
A workaround would be to use a Threshold filter to convert to a multiblock of 
unstructured grids, use the merge blocks filter and then extract this output to 
the client. You'll get some warnings about the data set not being a polydata 
(think about running a large simulation and trying to transfer all of that to a 
separate server or client). I'm assuming since you're trying to fetch the 
entire data set that the use case isn't for an overly large data set.
Cheers,
Andy

I have tried this with both ParaView 4.4.0 and 5.0.0 with the same results. The

bunch of vtm files that I can read into ParaView).

So I am wondering, are AMR meshes not supported by Catalyst Live? Do I have to 
handle AMR meshes differently when using Catalyst interactively?

Re: [Paraview] [EXTERNAL] BadAlloc Error

[Lloyd Brown]

Wellnot exactly.  Just for clarification, this is running pvserver,
with a completely headless Xorg instance.  I'm then connecting my
desktop's Paraview frontend instance to it over (presumably) a TCP
socket.  I'm not actually using SSH x11 forwarding, in this case.

But to answer your other question, here's the similar info from my setup:

> bash-4.1$ DISPLAY=:0.0 glxinfo | grep OpenGL
> OpenGL vendor string: NVIDIA Corporation
> OpenGL renderer string: Tesla K80/PCIe/SSE2
> OpenGL version string: 4.5.0 NVIDIA 352.79
> OpenGL shading language version string: 4.50 NVIDIA
> OpenGL extensions:
> bash-4.1$

So, if I'm interpreting that right, I should be able up to handle OpenGL
v4.5.0.

[Paraview] CxxOverlappingAMRExample with Catalyst Live

[Jim.Eliot]

Good afternoon,

I have been trying to use Catalyst Live with the CxxOverlappingAMRExample from 
the ParaView Catalyst Example Code repository [1] but I see an error when I try 
to visualise the data from a ParaView client. The client connects to the 
simulation successfully and PVTrivialProducer1 appears in the Pipeline Browser. 
The Information tab shows it as an Overlapping AMR Dataset with 3 levels. 
However, when I click on the PVTrivialProducer1 icon, ParaView prints an error 
then segfaults. The error is something like:

Warning: In /VTK/Parallel/Core/vtkCommunicator.cxx, line 394
vtkSocketCommunicator (...): Cannot receive vtkOverlappingAMR

I have tried this with both ParaView 4.4.0 and 5.0.0 with the same results. The 
example works fine when I am using non-Live Catalyst (i.e. it writes out a 
bunch of vtm files that I can read into ParaView).

So I am wondering, are AMR meshes not supported by Catalyst Live? Do I have to 
handle AMR meshes differently when using Catalyst interactively?

Many thanks,
Jim

[Paraview] req: please exclude userguide from binary installers

[Gena Bug]

Hi!

Paraview is developed fast and all new features are great! That's why I 
download all new releases including RC. However, installation binaries 
are huge because they include UserGuide in pdf. Excluding it decreases 
archive size from 379 Mb to 204 Mb (almost twice!) I know, most of you 
have high-speed Internet and you don't see the difference, however I'm 
not so lucky... It'll be great for me if developers exclude userguide 
from the installation binaries.


P.S. Userguide included in "Data, Documentation, and Tutorials" type of 
download, so there is also a kind of duplication.
