Re: [Paraview] Need help with programmable filter output

2012-11-30 Thread Berk Geveci

Output should be vtkTable. By the way, if you have numpy installed, this
could be done much more efficiently and in less code. See

http://paraview.org/Wiki/ParaView/Users_Guide/Python_Programmable_Filter
http://paraview.org/Wiki/ParaView/Users_Guide/Python_Calculator

You may also want to check the numpy documentation.

In general, if your data is medium to large, you want to avoid for loops
over all cells/points in Python.

Re: [Paraview] Compare two alike datasets

A pipeline copy & paste would be nice. Unfortunately it doesn't exist. The
closest things are macro and trace:

Re: [Paraview] (no subject)

2012-11-30 Thread Timothy Cale

Sebastien:

Good question:

My goal is to have a script which smooths results between simulation steps
(fortran codes).

I use paraview to view results, and the smoothing filter in paraview seems
to do what I want.

I want to start with a Trace-generated python script, and edit it to write
the vertices and element
info to a file (.ply would be nice) that the next code can read.

So, fortunately for me (in some sense), I decided to upgrade my ubuntu OS
to 12.10. This has
paraview 3.14.1-6build1 on its software list (aptitude).

This version corrected a bug (with pvpython) in the version of paraview
3.14 that I was using.
(I also spent a day trying to get/install other versions. That was not very
successful.)

Now if I import the trace generated py file, it pops up (and stays). Not a
very good image, but it is
a start!

Being new to python and paraview, this is quite a step.

Any suggestions as to how to write vertex/node info would be appreciated.

Thanks,
Tim

[Paraview] Fwd: (no subject)

Sebastien:

The data file I attached to the previous version of this update note was
too large.

I am resending the note with that file removed.

Update:

I am able to write a ply file using CreateWriter (see attached
first_stab.py and nanovtp files).
But the ply file is in binary.

I looked around for more than an hour to find out how to write the file in
ascii - to no avail.

Any hints?

Aside: When I put in 0 (for ascii) as a third arg. to CreateWriter,
pvpython complained about
having more than 2 arguments. I note that in the paraview users guide,
CreateWriter has
several arguments in some cases. help(CreateWriter) indicates that more
than 2 arguments
can be used:

>>> help(CreateWriter)

Help on function CreateWriter in module paraview.simple:


CreateWriter(filename, proxy=None, **extraArgs)

Creates a writer that can write the data produced by the source proxy in

the given file format (identified by the extension). If no source is

provided, then the active source is used. This doesn't actually write the

data, it simply creates the writer and returns it.

Regards,
Tim

Looks like they are replaced with:
-DVTK_INSTALL_INCLUDE_DIR
-DVTK_INSTALL_ARCHIVE_DIR
-DVTK_INSTALL_LIBRARY_DIR

which seems to work.


So where those library being copied then ?

Thanks,
