Hi Mac,

Welcome to ITK and VTK!

Here are some answers to your questions:

1) VTK is a visualization toolkit
ITK is an image processing and analysis toolkit

For an application like the one you are interested, you probably
want to combine both toolkits. VTK will provide functionalities
for visualizing of your models as well as the input images, while
ITK can be used for image segmentation and image registration.
Both toolkits work well together in an integrated environment.

You will have to decide what to use for managing the GUI
of your application, typical options are : FLTK, Qt, wxWindows
MFC, Java, and Tcl. If time is a premium, you probably want
to go for FLTK.

You are strongly encouraged to follow the tutorial sessions

http://www.itk.org/HTML/Tutorials

where you will find abundant details regarding the installation
and combined use of ITK and VTK.

You are also encouraged to look at the ITK SoftwareGuide

http://www.itk.org/ItkSoftwareGuide.pdf


2) Representing your model as a Mesh seems to be a good option.
You will find classes for representing Meshes both in ITK and
VTK. Examples on how to convert an ITK mesh into a VTK
one are available as part of the InsightApplications download.


3) VTK is a higher level layer on top of OpenGL. You will
save a lot of time by using VTK instead of programming
directly with OpenGL where you have to work with low
level primitives such as points and lines.



Regards,


Luis
