[Paraview] Paraview slice planes screenshot as images

2012-10-24 Thread Shiddiq Hashuro 
Hello,

I am trying to save applied slicing planes into jpeg (or any other kinds)
images. Is this possible? can anyone tell me how? If it can only be done
via python script, can you send me some parts of the script?
Also, is it possible to vary the slicing planes not by axis' range but by
some kind of elevation angle with a point as its orientation anchor?
really appreciate it..


thank you..
Shiddiq

[Paraview] Using VR-Style input devices

2012-10-24 Thread Johannes Zarl 
Hi,

I'm currently trying to configure ParaView for a CAVE-like environment. So far 
I was able to set up the pvservers correctly and even make headtracking over 
VRPN work.

Myself, I'm more of a newbie concerning ParaView, so I'm having some trouble 
understanding the state-file and how to define a wand-device so that ParaView 
can use it.

As far as I understand it, the VRPlugin reads the VRConnectionManager and 
VRInteractorStyles tags from the state-file and makes the connection to the 
server.

The Styles in VRInteractorStyles are supposed to reference a proxy name, that 
they are then attached to. So in this example:

Both these issues have been addressed in the development version and
the fixes will be included in the next release. You can try the

Re: [Paraview] PV3.14.1 Crash

2012-10-24 Thread Christian Richter 

Hi,

1) is a known bug in the release of 3.14.X : 
http://review.source.kitware.com/#/c/5242/
you can compile PV from source using the latest git or replace 
vtk/IO/vtkSTLReader.cxx with that one from the bugreport.

or only use binary-stl files.

2) I've the same issue when I copy PV from one client to another (both 
on Ubuntu 12.04), if i compile it from source this problem is gone away.


best wishes,
Christian

Re: [Paraview] Using VR-Style input devices

2012-10-24 Thread Aashish Chaudhary 
Hi Johannes,

Very recently, we have improved the VR API and related tools and now
the VR plugin comes with a GUI to configure connection managers and
interactor styles.

The way it works now is that you create a connection manager (lines
475 - 483), which will be generated by the GUI if used, and then for
the styles,
you would link it with the ID of the proxy and its specific property
that you want to control. Now said that the GUI shows you the name of
the proxy and not the ID
for obvious reasons. Then depending upon the type of the proxy and
property you specify a particular input from a HCI device. Currently
we support analog, button, and tracker.

The wiki here is bit old:
http://www.paraview.org/Wiki/ParaView/Users_Guide/CAVE_Display
We wrote a source article as well: http://www.kitware.com/source/home/post/66

This recent work is not in master yet (hopefully this Friday) but you
can checkout this branch: vtk_vr_improvements_new_gui
if you want to from paraview stage repository. The branch contains
bunch of bug fixes, and API improvements.

Hi Sohail,

Did you get a chance to look at the warnings for the
vtkIOGeometryCxx-TestWindBladeReader test for the
http://review.source.kitware.com/#/t/1396/ gerrit topic? It's going to need
to be fixed pretty soon if it's going to make it into the ParaView 4.0
release.

Thanks,

[Paraview] Vorticity computation from separated velocity array

2012-10-24 Thread 中田拓馬 
Dear all,

I am trying to compute vorticity from separated velocity vectors, but
pre-installed filter of paraview seems to require 3-components vector as an
input. Then, I have tried to use the "Python Calculator" filter to
construct it.  I put "hstack([VelocityX, VelocityY, VelocityZ])" into the
"Expression" field following the wiki.  However, it created just a copy of
VelocityX instead of 3-components vector.  How can I construct 3-components
array form separated velocity vectors?

I have also tried to use the "Programmable Filter".  But, it has been
really difficult for me and I could not just extract the vector from the
input.  The vectors live in vtkUnstructuredGrid in a vtkMultiBlockDataSet
and there are no function to extract Point Data form it.

Regards,

Makoto

Re: [Paraview] Vorticity computation from separated velocity array

2012-10-24 Thread Andy Bauer 
What version of ParaView are you using?  I was able to use
"hstack([VelocityX, VelocityY, VelocityZ])" with the Python Calculator
filter in v3.14.1. Alternatively you could try the Calculator filter with
"iHat*VelocityX+jHat*VelocityY+kHat*VelocityZ".

Re: [Paraview] Inconsistent results with the stream trace filter

2012-10-24 Thread Utkarsh Ayachit 
I was suggesting directly downloading the binaries, not even trying to
build the superbuild. Building using superbuild may be trickier,
especially since you're getting other build issues with building
ParaView itself. If you want to build from source, you'll have to edit
the versions.cmake file to use http:// instead of git:// for all git
repos.

The way you have set those properties at the end (the color/opacity), they
cannot be exported and viewed in Paraview. Since your 'contour' filter
produces a vtkPolyData, you can use vtkXMLPolyDataWriter to write it to a
vtp file which can then be opened with Paraview. I'd suggest you do that,
then setup the properties (color/opacity) in Paraview.

Yes, I noticed. Together with the information in a thread on this list
(http://www.paraview.org/pipermail/paraview/2012-July/025507.html), it was 
quite valuable, though...

Thanks, I didn't see that before.

That's great news -- I wasn't aware that the GUI work is this close to 
entering master. The screenshot looks promising. I will definitely try it out 
next week.

Thanks,

Re: [Paraview] PV3.14.1 Crash

2012-10-24 Thread Anton Gladky 
>> 2) by the way, when I open Paraview, there are lots of information (as shown
>> below) shown in Output Message,  how to solve it?

Utkarsh,

could you, please, say, where is it possible to get a patch, fixing this issue?
I will try to prepare fix-upload for Ubuntu 12.04. Strange, but
Paraview in Debian, built from the same source, has no such messages.

Thanks,

Anton
