Compiling, testing, adding custom functionality
Dr. Jean M. Favre

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  tahne  obpueilnd 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 bOupiltido snysltye pmr,o Create an extensible framework, aGnrod wd eav seleolfp-seurss.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

cmake iterative set-up
Set variables or boolean flags
Configture, correc
Once done, generate the makefiles
13/5/2009
ctest is run from the build directory
ctest

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")
