[Paraview] PEARC17 Visualization Contest

[Scott Pearse]

ATTENTION PARAVIEW USERS!

The PEARC17 Advanced Research Computing conference is currently accepting
entries for its yearly Visualization Contest and Showcase. This exhibition
is a chance for researchers to demonstrate the current discoveries that are
being revealed through High Performance Computing.  The submission deadline
is May 1, 2017.

PEARC17 is the successor to the yearly XSEDE conference held by the NSF.
It will take place in New Orleans, July 9-13, 2017, and is open to
professionals and students in advanced research computing.

Accepted submissions will be included in the PEARC17 proceedings and
displayed during the conference.  A visualization showcase will be held
where the researchers will be able to discuss the science behind their
work, and the tools used to create it.  A showcase winner will be announced
at the end of the conference.

Submissions need to include a movie file up to 250MB in size and a short
paper (no more than 3 pages including references) that


   1.

   Describes the key observables illustrated in the movie
   2.

   Explains how this visualization enhances the scientific process
   3.

   Explains what tools, techniques, and resources were used to produce the
   final product


Submissions are being done through EasyChair.  Submit your entry here
!

More information on the Visualization Showcase can be found here
!

Good luck!

Re: [Paraview] Duplicate Renderview

[Dan Lipsa]

Adam,
No, there is no 'create new view as copy of current view' command.

Re: [Paraview] [Non-DoD Source] PVSB on Mac OSX 10.12

[Angelini, Richard C (Rick) CIV USARMY RDECOM ARL (US)]

Chuck – I’ll try to force things with the –DUSE_SYSTEM_PNG=OFF. It is my
intention to allow PVSB to build the png libraries – and it seems to work
everywhere except for OS X 10.12 …
I can see in the 10.12 build that PVSB did indeed build the png libraries,
and there are png entries in superbuild/install/lib and
superbuild/install/include – but the ParaView cmake is not picking up this
information. Why it only fails here (or works everywhere is) is the
$10,000  mystery ….

When using the superbuild, ParaView should always be using a "system" PNG.
The diggerence is whether that will be provided by the OS or the superbuild.
Either way, it's external to the paraview subproject.  Try explicitly
setting -DUSE_SYSTEM_png=OFF when configuring the superbuild.  I'll look
into why the superbuild doesn't properly handle this in the first palce but
explicitl;y setting the option should make your build work.

Re: [Paraview] Duplicate Renderview

[Adam Dershowitz]

Maybe my question wasn’t clear.  What I want to know is if there is any way to 
copy the settings from one view to another.  For example if I turn on the 
visibility of a few filters (click on the eye) and then turn off others, and, 
finally make some other changes such as coloring of object I can  set up a view 
that I like.  Next, I want to start from that identical view to the one that I 
setup, but just move the camera from that view.  So, I want to setup things how 
I want (filter visibility, colors etc) then make a second view that is a copy 
of that first view.  Then, I want to start from that second view to move my 
camera etc.

As you indicate below, I can edit things in a view and change the visibility in 
each view.  But, I already have a view that I like, and now I want to make that 
into a split view with the identical visibility etc.  Do, I have to manually 
start turning on and off all of the filter visibility etc?
What I am looking for is “copy current pipeline visibility” and then apply that 
to another view.  Or, “create new view as copy of current view”  Then, I can 
start making changes from that point.

I don’t see a way to do that.

Thanks,

-- Adam

Adam,
You can show the same data in different views. Just click on the eye next to 
the filter which output you want to see.

So for instance, if you show the data from the last filter in one view, 
clicking on the eye next to that filter will show the same thing in the second 
view.

So, the starting point does exactly what you want. Note that the settings for 
how data is displayed in a view are stored per (filter, view) pair.
You can change those by selecting the filter and the view you want and changing 
the display settings.

I hope this helps,
Dan

I’m using Paraview 5.2, although I also looked around briefly for a way to do 
this in 5.3RC1.

Re: [Paraview] Query on Paraview CPU vs GPU acceleration

[Chuck Atkins]

Hi Bishwajit,

It looks like your GPU build isn't actually building against the GPU.  In
order to use the GPU with the NVidia driver, you either need to use an X
server or use EGL.


-DVTK_USE_X=OFF
>

In this case, you have disabled X but not enabled EGL so you're left with
OSMesa when you really intended to use the GPU instead.  See
https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/
for more details on configuring ParaView to use EGL.

Re: [Paraview] [Non-DoD Source] PVSB on Mac OSX 10.12

[Angelini, Richard C (Rick) CIV USARMY RDECOM ARL (US)]

A build using the same cmake command completes without the
VTK_USE_SYSTEM_PNG problem on an  OSX 10.11 system. Both systems are
running the Xcode 8.2.1.   I tried both cmake 3.6.3 and 3.7.2 on the OX
10.12 system and both versions result in the same cmake configuration
problem, so it appears to be an issue specific to OS X 10.12 …

I'm building PV 5.3-RC2 on a Mac OSX 10.12 and the build is getting hosed.
(the build fails while building ParaView, can't find a missing 
include file).When PVSB configures Paraview, it is setting the cmake
flag VTK_USE_SYSTEM_PNG=ON and it should be OFF. In the top level cmake,
the value is set to OFF.


292 mac> grep PNG CMakeCache.txt
VTK_USE_SYSTEM_PNG:UNINITIALIZED=OFF

If I re-run cmake in the paraview build directory and turn off
VTK_USE_SYSTEM_PNG, I get a clean build.

Re: [Paraview] Coloring with vtkBlockColors

[kenichiro yoshimi]

Hi,

In order to color blocks by "vtkBlockColors", I just need to call
SetScalarColoring() like below:
 vtkSMPVRepresentationProxy::SetScalarColoring(repr->getProxy(),
"vtkBlockColors", vtkDataObject::FIELD);

This may work even if "vtkBlockColors" array info is not contained in
vtkPVDataSetAttributesInformation although I do skip in this case.

Thanks,
yoshimi

[Paraview] Query on Paraview CPU vs GPU acceleration

[Bishwajit Dutta]

Hi All,


I am trying to compile and run Paraview 5.0.1 with both CPU and GPU
acceleration on ubuntu server with NVIDIA cards. I am able to successfully
run a pvpython script.

However in both below cases I am able to see CPU power getting consumed
when the script is run.
I am confused on the accelerator being used.

For GPU:
===
I compiled with the below options:

cmake ../ -DBUILD_TESTING=OFF -DCMAKE_BUILD_TYPE=Release
-DPARAVIEW_ENABLE_CATALYST=ON -DPARAVIEW_ENABLE_PYTHON=ON
-DPYTHON_LIBRARY=$PYTHON_LIBRARY -DPYTHON_INCLUDE_DIR=$PYTHON_INCLUDE_DIR
-DPARAVIEW_USE_MPI=ON -DMPI_HEADER_PATH=$MPI_HEADER_PATH
-DCMAKE_INSTALL_PREFIX=$BD_INSTALL_PATH -DPARAVIEW_BUILD_QT_GUI=OFF
-DVTK_USE_X=OFF

For CPU:

I compiled mesa, glu libs etc. and the compiled Paraview with the below
options

I run the script with
#pvpython --mesa-llvm 

cmake ../ -DBUILD_TESTING=OFF -DCMAKE_BUILD_TYPE=Release
-DPARAVIEW_ENABLE_CATALYST=ON -DPARAVIEW_ENABLE_PYTHON=ON
-DPYTHON_LIBRARY=$PYTHON_LIBRARY -DPYTHON_INCLUDE_DIR=$PYTHON_INCLUDE_DIR
-DPARAVIEW_USE_MPI=ON -DMPI_HEADER_PATH=$MPI_HEADER_PATH
-DCMAKE_INSTALL_PREFIX=$BD_INSTALL_PATH -DPARAVIEW_BUILD_QT_GUI=OFF
-DVTK_USE_X=OFF -DOPENGL_INCLUDE_DIR=$BD_INSTALL_PATH/include
-DOPENGL_gl_LIBRARY=$BD_INSTALL_PATH/lib/libOSMesa.so
-DOPENGL_glu_LIBRARY=$BD_INSTALL_PATH/lib/libGLU.so
-DVTK_OPENGL_HAS_OSMESA=ON -DOSMESA_INCLUDE_DIR=$BD_INSTALL_PATH/include
-DOSMESA_LIBRARY=$BD_INSTALL_PATH/lib/libOSMesa.so

Thanks in advance for help on this.

If this all is running in CPU then how do I compile it for GPU without
x-windows (i.e. on server)


BR,
Bishwajit
