Paraview
--------

Here you can find a few notes how to get you started on Debian.
Thourough, full official documentation can be found at http://paraview.org.

Load your vtk file
------------------

$ paraview --data=file.vtk

Hit "Apply". Depending on what you have put into the file you can see inside
your geometry by: hit the "Clip" button, "Apply".

Paraview and Parallel Data (Mpi)
--------------------------------

Say that you have data (in ensight case and sos format) spread over N
processors, in order to view your data you need to start N paraview
processes

$ mpirun -np N paraview

or 

$ paraview

File -> Connect

Click on "Add Server" 

type the server name (e.g. localhost)

then click on "Configure" and enter  the command 

mpirun -np N pvserver

then click on "Connect" and you are now ready to visualize your
parallel data

Python scripting
----------------

It's as simple as this:

    $ python
    Python 2.5.2 (r252:60911, May 28 2008, 19:19:25) 
    [GCC 4.2.4 (Debian 4.2.4-1)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from paraview import servermanager as sm
    >>> sm.Connect()
    Connection (builtin:5)
    >>> cone = sm.sources.ConeSource()
    >>> view = sm.CreateRenderView()
    >>> sm.CreateRepresentation(cone, view)
    vtkConeSource : [ ...........]
    <paraview.servermanager.GeometryRepresentation object at 0xb353118c>
    >>> view.StillRender()
    vtkPVGeometryFilter : [ ...........]
    vtkPainterPolyDataMapper : [ ...........]
    vtkPainterPolyDataMapper : [ ...........]


This will show the cone. You can automatically reposition the camera by:

    >>> view.ResetCamera()
    >>> view.StillRender()
    vtkPainterPolyDataMapper : [ ...........]
    vtkPainterPolyDataMapper : [ ...........]
    >>> 


This should get you up and going, now learn all the details from the excellent
guide into paraview python scripting at:

http://www.paraview.org/Wiki/images/2/26/Servermanager.pdf

Paraview is built against python2.5 only (it works with python2.4, but you
would have to compile it yourself, changing build depends and debian/rules).

Problems
--------

 o paraview crashes while saving screenshot

   see http://openfoam.cfd-online.com/forum/messages/1/4438.html

   add the following line in  /etc/X11/xorg.conf  file in ServerLayout section

   Section "ServerLayout"
   Option "AIGLX" "false"
   EndSection
