I think you are right - I just commented out that error message and things worked for me.

I have to say, it actually worked pretty great for me - see attached. I think that's valuable enough that we should go ahead with putting it in the trunk.

But I do think we should add a progress dialog for the apply step, and also disable the volume slider until is is actually useful.

I was also thinking that a self test would be good, but not strictly essential.

Also, it needs to handle undo/redo correctly.

Andrey,

when I worked with Harini on the UI for growcut we used the initialization provided by the user to define a volume of interest. Essentially you take the extent of the initialization add a 50% safety margin and assume the VOI has the same dimension in all directions. Such an approach would allow to remove one of the two sliders in your interface.

Another comment from Ron: make sure the slider has sufficient resolution to allow precision

initial commit to trunk in r21758.

Remaining item: self-test
