ITK/Complete Setup

This page will describe setting up the Kitware tools on an Ubuntu (or any Debian, really) workstation. I assume that you have a basic install of Debian/Ubuntu.

Preparing your system

For ITK, install the following packages:

• gcc
• g++
• make
• cmake

For VTK, install the following packages:

• tcl8.4-dev
• tk8.4-dev
• libgl1-mesa-dev

For FLTK, install the following packages:

• libfltk1.1-dev
• libglu1-mesa-dev

For QT, install the following packages:

• q3-apps-dev
• qt3-dev-tools
• libqt3-i18n

Getting the sources

Do this in your home directory. It will take a long time, depending on your connection speed.

ITK

 cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight login

password: insight

 cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co Insight

You can also get the Insight documentation (optional):

 cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co InsightDocuments

A variety of Insight demo applications are available in the InsightApplications module (optional):

 cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co InsightApplications 

VTK

 cvs -d :pserver:anonymous@public.kitware.com:/cvsroot/VTK login

password: vtk

 cvs -d :pserver:anonymous@public.kitware.com:/cvsroot/VTK checkout VTK

For testing purposes you might wish to checkout the CVS VTKData (optional):

 cvs -d :pserver:anonymous@public.kitware.com:/cvsroot/VTKData login

password: vtk

 cvs -d :pserver:anonymous@public.kitware.com:/cvsroot/VTKData checkout VTKData

KWWidgets

 cvs -d :pserver:anoncvs@www.kwwidgets.org:/cvsroot/KWWidgets login

password: <just hit return>

 cvs -d :pserver:anoncvs@www.kwwidgets.org:/cvsroot/KWWidgets co KWWidgets

Asssuming you did all this in your home directory, you have the directories Insight, InsightDocuments, InsightApplications, VTK, VTKData, KWWidgets

Make and Compile

ITK

As in the ITK Software Guide:

 mkdir $HOME/Insight-bin
 cd $HOME/Insight-bin
 ccmake ../Insight

Hit c to configure, then g if everything went well. Then type

 make

This will take a while, depending on the speed of your machine. It took about ~4hrs on a P4-2.8GHz with 2GB RAM.

VTK

 cd $HOME/VTK
 ccmake .

Hit c to configure, then g if everything went well. You will probably have to hit c a number of times, setting variables in between. I set BUILD_EXAMPLES and VTK_WRAP_TCL to ON. When I tried to compile InsightApplications later, it required VTK built with VTK_USE_HYBRID, so set that too.

InsightApplications

 mkdir $HOME/IA-bin
 cd $HOME/IA-bin
 ccmake ../InsightApplications

Hit c to configure, then g if everything went well. I set ITK_DIR to $HOME/Insight-bin, VTK_DIR to $HOME/VTK and USE_FLTK to ON

KWWidgets

 cd $HOME/KWWidgets
 ccmake .

Hit c to configure, then g if everything went well.

Running the Examples

 $HOME/Insight-bin/bin

will have all of the examples in the ITK Software Guide. They are standalone executables.

 $HOME/KWWidgets/bin 

will have all the examples from KWWidgets. They are standalone executables. KWWidgetsSetupPaths.sh is a useful script that you should run before trying to run any tcl or python code that uses KWWidgets.

 $HOME/VTK/bin

will also have a bunch of executable files. An important one is $HOME/VTK/bin/vtk, use that one to run any examples written in tcl:

 $HOME/VTK/bin/vtk $HOME/VTK/Examples/ImageProcessing/Tcl/Contours2D.tcl

Writing a Simple Program (ITK)

Read the ITK Software Guide. Start with the Hello World example there. All of the code in the ITK Software Guide is in the Examples subdirectory of the InsightToolkit. Most simple command-line programs can be made by slightly modifying one of the examples from the ITK Software Guide. For example, I modified the Examples/Filtering/SubsampleVolume.cxx file to use the WindowedSincInterpolateImageFunction with the Welch window.
