Re: [Paraview] FW: [Paraview-developers] How do I create a multi-level array selection box for a reader?

2013-04-26 Thread burlen


Josh,

hmm, I was looking on the wiki for an example of a custom panel and I 
learned custom panels are now/soon deprecated! There are some examples 
around, I think the exodus reader has one, the pqSQPlaneSource is 
another, but you probably should focus on the new approach if you want 
it to work in later release of PV. http://paraview.org/Wiki/Properties_Panel

I don't think the xml is that sophisticated, you're probably going to 
need a custom panel for that.

Re: [Paraview] Delauney 3d

2013-04-26 Thread Moreland, Kenneth

I responded to Alan directly, but I'll repeat the response for the list as well.

The reason why you see white lines is that the alpha parameter causes the 
Delaunay 3D filter to create lines (or triangles) if they fit within the 
circumsphere smaller than alpha and the tetrahedron does not.  These lines are 
rendered without shading, so they show up as stark white streaks in the 
rendering.

The most straightforward solution to get what you want is to filter out any 
cells that are not tetrahedra.  I don't know of a filter designed for that, but 
you can do it with a Programmable Filter with the following script.  (Watch out 
for any newlines that an email program might insert.)

from paraview.vtk import vtkFiltersCore

input = self.GetUnstructuredGridInput()
output = self.GetUnstructuredGridOutput()

typesArray = input.GetCellTypesArray()
typesArray.SetName('__types__')

inputWithTypes = vtk.vtkUnstructuredGrid()
inputWithTypes.ShallowCopy(input)
inputWithTypes.GetCellData().AddArray(typesArray)

threshold = vtk.vtkFiltersCore.vtkThreshold()
threshold.SetInputData(inputWithTypes)
threshold.SetInputArrayToProcess(0,0,0,'vtkDataObject::FIELD_ASSOCIATION_CELLS','__types__')
threshold.ThresholdBetween(9.5, 10.5)
threshold.Update()
thresholdOutput = threshold.GetOutput()

output.ShallowCopy(thresholdOutput)
output.GetCellData().RemoveArray('__types__')

Subject: [EXTERNAL] [Paraview] Delauney 3d

I have a csv file of points.  After running it through the table to point 
filter, I am running the delauney 3d filter on it.  The dataset looks like a 
watermelon rind.  Unfortunately, the red part of the watermelon is solid.  
Fortunately, changing the alpha variable fixes this – deleting the red “meat” 
part of the watermelon.

My issue is that we are ending up with lots of white lines all over the outside 
of the solid object.  Think of my water melon rind as the outside green layer 
with the white rind, covered with white spider webs.

Has anyone seen this, and is there a fix or workaround?

Thanks,

Alan

Re: [Paraview] Output of ParallelUnstructuredGridWriter running on multiple nodes

2013-04-26 Thread Hong Yi

Thanks, Andy. In our case, users only want to observe one integrated velocity 
value (one output value from Integrate Variable Filter) for the slice at each 
time step so that they can determine from which time point on this velocity 
value stops changing which indicates to them the simulation has converged. So 
this large amount of output files from the ParallelUnstructuredGridWriter is 
hard to serve this purpose. I am wondering whether there is a way for me to 
export the SpreadSheetRepresentation view (to view Integrate Variable Filter 
output) as a screen capture when I export pipeline in python for coprocessing? 
It looks like the "Export State" GUI for coprocessing only allows to export 
rendered views, not other types of views. If not, I am thinking perhaps I can 
write a customized writer plugin to only export the needed output value for our 
purpose and to make this writer only exports one file for each time step 
regardless of the number of processors it runs on.

Thanks for any more information you can provide!

Hi,
The parallel XML data set writers all write independently of each other (no MPI 
communication is needed in the writers). Because of this they can't tell 
process 0 when writing it's meta-data file that it doesn't need to write out 
meta data for them.

I am working on a ParaView plugin that has a file as a parameter. What
would be the best property type to use for this? A string property
would work, but it would be great if there were a property that
brought up a file browser to locate the file. Does one exist?

Re: [Paraview] ?????? ??????RE: error when open tecplot(.plt) files

2013-04-26 Thread Richard GRENON

Hi Zhang.

Just a last info: since my last mail, I have made some tests with old
binary Tecplot (.plt) files, and I discovered that some files are
readable, but some files are not readable and give the same error
message. In fact, it depends on the Tecplot version that has built these
files. So, if you have problems with old (.plt) files, you may try to
convert them into a recent version of the (.plt) format using a recent
Tecplot release before reading them with Paraview.

Have a good week-end.

Richard.

Hello.

Glad to see that you have solved your problem. It is true that you
need the Vislt software for reading Tecplot files, but this software
is included in the last Paraview release 3.98.1. I am using the last
binaries found on the Paraview download pages, and I can read Tecplot
binary or ASCII files without adding software.

On older Paraview releases, the Vislt software was delivered as a
plugin that was not activated by default. In that case, you had to go
through the menu "Tools->Manage plugins", then select the "Vislt"
plugin, click the "Load selected" button, close Paraview, and finally
reopen Paraview to get the plugin activated. So, check your Paraview
version, and you may want to update it for the last 3.98.1 release.

But take care: there are two Tecplot readers. If you open a (.tp)
ASCII Tecplot file, you will have the choice between "Tecplot Files"
or "Tecplot Files (Vislt)". I don't know exactly what are the
differences, but if a reader fails, try the other.

But the Tecplot readers are not perfect, and that may explain your
ERROR message. Sometimes, with Tecplot ASCII files, I have to remove
from the header some options that the readers do not recognize. Try to
have the simplest headers without "exotic" options when using ASCII
files, and the readers will be OK.

If you have again problems with (.plt) files, feel free to provide a
(short) sample file.
