[Insight-users] How do you set up scripting of ITK, VTK and KWWidgets?

[Kent Williams]

I would like to do some rapid prototyping using TCL scripts, using the 
ITK, VTK, and KWWidgets toolkits together.

I've been spelunking mailing list archives, Kitware WIKIs, and such, 
without finding any concise description of the best way to go about 
doing this.  My understanding so far is that I will need:

1. ITK -- wrapped for TCL
2. VTK -- wrapped for TCL
3. KWWidgets -- wrapped for TCL
4. ConnectVTKITK

What's not clear is how I'd go about putting these together in the TCL 
environment -- can they all be loaded as packages? What environment 
variables determine how the packages are found?

There appear to be various examples that come with the various toolkits 
that A) use VTK and ITK together or B) use VTK and KWWidgets together, 
but nothing that closes the circle.
I know that Slicer is an application that essentially does this, but 
unless I'm missing something, it's never explained how it works. It's 
embarrassing to have to ask, since I've been contributing code to 
Insight for the past few years, but I've had my blinders on and learned 
mostly about my little corner of ITK.

Does anyone want to give it a go, or point me to an example that makes 
it clear how to get everything configured together?
