Official release

Version 3.4.0 binaries can be downloaded from www.paraview.org

No MPI is provided, but paraview can be connected to a remote parallel server

No pluggins can be added

Compiling the source code

Version 3.4.0 source code can be downloaded from www.paraview.org/files

ParaView must be compiled out-of-source, i.e. inside a directory with a different name

I suggest having two directories called:

 ParaView3

 ParaView3Build

13/5/2009

cmake www.cmake.org

 You must install and use cmake to compile ParaView

CMake was developed to enable:  Develop     t a h n e     o b p u e il n d  source, cross-platform tool to  manage process,  Allow the use of native compilers and systems,  Simplify the build process, al vide a user-interface to manage the  b O u p il ti d o  s n ys l t y e  p m r , o    Create an extensible framework,  a G n ro d  w d   e a v  s el e o lf p -s e u rs s . t   aining community of software users

cmake 2.6

C:\CMake 2.6\doc\cmake.html cmake is the obligatory first step to compile anything

ctest is for developers (and the more curious folks) C:\CMake 2.6\doc\ctest.html

ctest is the test driver program. cmake-generated build trees created for projects that use the ENABLE_TESTING and ADD_TEST commands have testing support.

467 tests are available for version 3.4.0

Running other tests

ctest searches all Testing sub-directories for name matches, then run the test and [optionally] compare the image with a “valid” image previously generated. Command: "C:/ParaView3Build/bin/Debug/GraphicsCxxTests.exe"  "BoxClipPolyData" "-D" "C:/Program Files/VTKData" "-T"    "C:/ParaView3Build/VTK/Testing/Temporary" "-V" "Baseline/Graphics/BoxClipPolyData.png"

ctest –R FrustumClip -V GraphicsCxxTests FrustumClip –I

Testing with Python

With paraview:  Get a Python Shell from the Tools menu  Type “servermanager.demo4(“/filepath/can.ex2”)”

With pvpython:  pvpython < demo4.py

With pvbatch:  pvbatch –use-offscreen-rendering demo4.py

13/5/2009

Testing with Python: demo4()

from paraview import servermanager def demo4(fname="/Users/berk/Work/ParaViewData/Data/can.ex2"): if not servermanager.ActiveConnection: servermanager.Connect() reader = servermanager.sources.ExodusIIReader(FileName=fname) view = servermanager.CreateRenderView() repr = servermanager.CreateRepresentation(reader, view) view.StillRender(); view.ResetCamera(); view.StillRender(); c = view.GetActiveCamera() c.Elevation(95) servermanager.AnimateReader(reader, view, "/tmp/foo.mpg")

demo4("/local/ParaViewData3.4/Data/can.ex2")
