Welcome to the Insight Registration and Segmentation Toolkit (ITK)
-----------------------------------------------------------------
This is the fourth public release of ITK (Release-1-2). The ITK developer
community appreciates any feedback that you may have regarding this
software. Join the ITK user mailing list (instructions later) and post your
feedback there. Warning: since the software is young, and this is an early
release, the API to the software will likely change in the future.
Here are suggested steps for the ITK beginner. Please refer to
http://www.itk.org for more information. Another document, found in
Insight/Documentation/InsightStart.pdf is highly recommended.
1) Get the software. We strongly suggest that you obtain the pre-packaged
source code distributions (binaries/executables are not yet available).
http://www.itk.org/HTML/Download.htm
You may also obtain CVS access. (This requires the CVS executable and
access to ITK's source code through your repository.) To check out the ITK
version 1.2 release, use the following procedure:
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight login
(respond with password "insight")
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co \
-r Release-1-2 Insight
The current development version of ITK is available using the following
process. Please realize that the development version is inherently less
stable than official releases. If you access the development version, you
will want to monitor code quality at the ITK Dashboard
http://public.kitware.com/dashboard.php?name=itk.
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight login
(respond with password "insight")
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co Insight
2) The software is compiled using CMake http://www.cmake.org. CMake
generates Makefiles on Unix platforms, and Windows workspaces (or
appropriate) build files according to your compiler, operating
system, and other system variables.
If at all possible, obtain the pre-compiled CMake binaries. Binaries
for Windows and various Unix flavors are available from
http://www.cmake.org/CMake/HTML/Download.html. On Windows, run the
CMSetup.exe to install CMake. On Unix, uncompress and untar the
package and place the executable in a location in your path.
On Windows, run CMake by clicking on CMakeSetup.exe. You have to point
CMake to the source directory (e.g., Insight), a build directory (where
the binaries and object files go), and choose the compiler. The GUI allows
you to choose build options and configure the build. Rerun CMake (by
selecting "Configure") until all "red" entries disappear. Then select
"Ok". This will produce a compiler workspace in the directory that you
selected.
On Unix, run "ccmake". This simple, curses-based GUI to CMake allows
you to configure the build process. First create a build directory
in which to generate object code and executables. Cd into this
directory and specify your C and C++ compilers with the environment
variables CC and CXX.
Depending on the shell that you use, this will be done with the
command:
setenv CC your-c-compiler
setenv CXX your-c++-compiler
or with the command
export CC=your-c-compiler
export CXX=your-c-compiler
Next invoke "ccmake ../Insight" assuming that your build
directory is a sibling directory to Insight/. While running
ccmake, changes are made using the arrow keys to move over an
option, and the "Enter" key to edit it. Type "C" to configure
the build. As long as "*" appear next to any entries, keep
running CMake until none exist. Then type "G" to generate
makefiles and exit. Then run "make" in the build directory.
If you have difficulty with CMake, please refer to http://www.cmake.org
for additional instructions. It is possible to obtain CVS access and
compile CMake if absolutely necessary.
3) Join the mailing list. Go to
http://www.itk.org/mailman/listinfo/insight-users and follow the
instructions there. You may choose to receive a digest version of the
mail to minimize traffic.
4) Learn the system. Start by looking at the examples found in the
Insight/Examples directory. Note that this code is heavily
commented and works with the ITK Software Guide (found at
http://www.itk.org/ItkSoftwareGuide.pdf). (To build the examples,
make sure the CMake flag "BUILD_EXAMPLES" is on.) You may also wish
to peruse the many tests found in Insight/Testing/Code.
If you would like to be more ambitious, a separate checkout of ITK
applications is available. Please do not attempt this until ITK and
its examples are building correctly (as described previously). The
InsightApplications may be difficult to build because of their
dependency on external packages like VTK, FLTK, and Qt.
TO obtain the InsightApplications checkout via CVS:
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/InsightApplications co \
-r Release-1-2 InsightApplications
