Re: [Paraview] Writer plugin with selection of data arrays to output

[Sergey Alexandrov]

Hi Dennis,

Thanks for the suggestion! Honestly, at first I was skeptical about your
advice because it looked very
similar to my first solution that I outlined in the beginning of this
thread. However, as soon as I examined
the XML code for the PassArrays filter, I realized that this is exactly
what I need. It uses some built-in
ParaView magic to fill the list with data array names, so there is no need
for me to "inject" my custom
code to populate it. Neat!

Thanks again!

Cheers,
Sergey

Re: [Paraview] Writer plugin with selection of data arrays to output

[Dennis Conklin]

Sergey,

You could combine the PassArrays filter and your custom writer into a Custom 
Filter and then Expose the properties of Cell Data Arrays and Point Data Arrays 
from the PassArray filter within your Custom Filter.

This would allow your users to select which arrays to pass and write them out - 
I think this would do exactly what you want, but you should test it.

Re: [Paraview] Writer plugin with selection of data arrays to output

[Cory Quammen]

Hi Sergey,

I'm not aware of another writer that has the behavior you describe of
saving out specified data arrays. As a result, there isn't any
existing code to select the data arrays to be saved. There are a
number of readers that do support which arrays to load, but it's not
really possible to reuse that infrastructure without some additional
ParaView development work to support selecting arrays to be written.

A workaround would be to use a Pass Data Arrays filter to select the
data arrays, then save the Pass Data Arrays output to your custom
writer.

Hope that helps,
Cory

[Paraview] Writer plugin with selection of data arrays to output

[Sergey Alexandrov]

Hi,

I am trying to implement a sink algorithm (writer) to output point clouds
in my custom format. The points may have multiple data
arrays, and the writer should provide the user with an option to select
which of these arrays are to be output.

Unfortunately, I am not able to find any wiki pages or articles that
explain how to implement such a writer. Also, I do not find any
existing writers with this functionality. The most similar things I found
are:

1) AMR base particles reader
.
It provides a facility to select which data arrays are to be read from a
file. Basically, when the user
sets the filename, the reader loads the meta-information about available
arrays from the file, and then these are displayed in
ParaView properties panel. The user can tick the arrays he wants and press
"Apply" to read. I can not figure out how to apply this
in my writer, because the only extension point for writers is the
WriteData() function. It is called after the user has pressed the
"Save" button, which is too late. In fact, I want to "inject" some code
between the moment the user chose the output filename (and
hence the writer to use), and the moment a dialog window with the
properties of the writer is shown.

2) Wiki page on writing readers
.
There is an example how make a drop-down list to select which input array
to process. Perhaps
I could add this to the writer, however it does seem to support only a
single array choice, whereas I need multiple.

I would be very grateful for suggestions on how to implement the
functionality I need. Examples of existing readers would be
great. Or if there is definitely no "official" clean way to implement this,
please also let me know.

Cheers,
Sergey

Re: [Paraview] Writer plugin?

[Biddiscombe, John A.]

David

I used to make my writers the same as filters and even allow them to shallow 
copy their input to the output. Then in paraview they can appear in the filters 
menu and can be inserted in the middle of a pipeline and each time a render is 
activated, the writer would be triggered. (I used it for saving particles out 
from animations of advected flows). (you can check if the timestep has changed 
or other stuff is different and skip writes if necessary).

Adding the writer as a filter is an easy option!

Thanks! Changing the ProxyGroup to filters and the WriterProxy element to a

it as a writer, but at least I can move on to the actual work.

Re: [Paraview] Writer plugin?

[David Thompson]

Hi Burlen,

 The WriterProxy may have a special file_name_method attribute that needs to 
 be set. I'm not sure if that's required, optional, or long since obsolete 
 since I haven't used our plugin in quite a while.

I did see the file_name_method (and supports_parallel and parallel_only) 
attribute, but not all of the writers have it. When I add it, nothing happens.

Thanks,
David

[Paraview] Writer plugin?

[David Thompson]

Hi all,

I have a ParaView plugin that contains a new writer which I would like to 
expose. However, while the plugin does properly expose a new view and 
representation, the writer does not appear to get added (when I try to save a 
vtkTable such as a statistics filter output, it doesn't appear as an option).

1. Is there any documentation for adding writers in plugins? This page has a 
comment or two but doesn't appear complete:

http://www.paraview.org/Wiki/ParaView/Plugin_HowTo

2. If you're willing to look over the XML, I've attached it below. See any 
mistakes?

Thanks,
David

Re: [Paraview] Writer plugin?

[Andy Bauer]

I think you may be missing the FileName property. I thought that PV looked
for that attribute to know that it should be classified as a writer. Also,
you'll want to hide that property.

So:
  StringVectorProperty name=FileName
command=SetFileName
number_of_elements=1
label=File Name
Documentation
  The file name.
/Documentation
  /StringVectorProperty


and:
  Hints
Property name=Input show=0/
Property name=FileName show=0/
WriterFactory extensions=json file_description=JSON tabular
data /
  /Hints

Adding the FileName property and hints did not work.

[Paraview] Writer plugin C++ code example

[Nicholas Yue]

Hi,

I checked out from the git repository of paraview and build with 
PARAVIEW_INSTALL_DEVELOPMENT=ON


While looking at the plugins directory

some-path/Paraview_git/Examples/Plugins/Writer

I can see the directory contains the XML files for writer plugin 
but no C++ code to illustrate how one should write the plugins in C++


On closer examination, the CMakeLists talks about building reader

My interest is to write geometry information out for rendering 
using and external software e.g. RenderMan.


Any pointers or URL I can start looking at ?

Regards

Re: [Paraview] Writer Plugin cannot be loaded

[Natalie Happenhofer]

Well,
I tried everything, changing the cmake_install_prefix and so on, and lastly I 
checked  the CMakeLists.txt file  which took care of the Plugin and there I 
found a mistake.. a library name spelled incorrectly. I changed that and now I 
get
linker errors which I do not know how to get rid of:

No rule to make target `/usr/local/unpackaged/libcommon.so', needed by 
`bin/libVdcWriter.so'.  Stop.

That libcommon.so is a library which is already build, but not by paraview, and 
I want it to be linked to my code. Here
is the CMakeLists.txt:

INCLUDE(${ParaView_SOURCE_DIR}/CMake/ParaViewPlugins.cmake)

INCLUDE_DIRECTORIES(
  ${VTK_INCLUDE_DIR}
  ${PARAVIEW_INCLUDE_DIRS}
  ${VTKEXPAT_SOURCE_DIR}
 )

FIND_PACKAGE(Qt4)
INCLUDE(${QT_USE_FILE})

FIND_PACKAGE(ParaView REQUIRED)
 INCLUDE(${PARAVIEW_USE_FILE})

FIND_PACKAGE(VDC REQUIRED)
INCLUDE_DIRECTORIES(${VDC_INCLUDE_DIR})

FIND_PACKAGE(NETCDF REQUIRED)
INCLUDE_DIRECTORIES(${NETCDF_INCLUDE_DIR})

IF (PARAVIEW_BUILD_QT_GUI)
  ADD_PARAVIEW_PLUGIN(VdcWriter 1.0
GUI_RESOURCE_FILES GUIVdcWriter.xml
SERVER_MANAGER_XML SMVdcWriter.xml
SERVER_MANAGER_SOURCES vtkVdcWriter.cxx
)
ELSE (PARAVIEW_BUILD_QT_GUI)
  ADD_PARAVIEW_PLUGIN(VdcWriter 1.0
SERVER_MANAGER_XML SMVdcWriter.xml
SERVER_MANAGER_SOURCES vtkVdcWriter.cxx
)
ENDIF (PARAVIEW_BUILD_QT_GUI)

TARGET_LINK_LIBRARIES(VdcWriter ${EXPAT_LIBRARY} ${NETCDF_LIBRARY} 
${COMMON_LIBRARY} ${VDF_LIBRARY}

I believe that target_link_libraries command is not correct, but how can I link 
all these libraries to my code?

thx
Natalie

 It sounds like the dynamic linker/loader , ld, isn't finding your 
 libVdcWriter.so library. first you can verify by running ldd on your 
 plugin and searching for not found. like this:
 
 ldd /path/to/libMyPlugin.so | grep not found
 
 This will list the libraries that are not found. There are a number of 
 ways to remedy such an issue. The easiest (especially for debugging 
 purposes) is to use LD_LIBRARY_PATH on the command line to add locations 
 to ld's search path. You know where the missing library is located then 
 you can run paraview like this:
 
 LD_LIBRARY_PATH=/path/to/missing/lib/folder /path/to/paraview
 
 or you can export this variable in your shell.
 
 
  and by the way, a stupid question: linux .so - files are equivalent to 
  windows .dll-files, true? so while I´m loading my plugins as .dlls in 
  windows, with linux they have the ending .so, right?

Re: [Paraview] Writer Plugin cannot be loaded

[Michael Jackson]

You can try the following:

SET(PARAVIEW_ADDITIONAL_LIBRARIES
 ${PARAVIEW_ADDITIONAL_LIBRARIES}
 ${vtkexpat} ${NETCDF_LIBRARY} ${COMMON_LIBRARY} ${VDF_LIBRARY})

BEFORE the line

IF (PARAVIEW_BUILD_QT_GUI)


Also ParaView provides its own expat library which you may be able to  
use instead of your own or a system one. vtkexpat


Hope that helps
