Why not read the imageJ documentation or even look at the source code?
Google search quickly leads to
stacks - 3D project:

VolumeJ

then you need to read the docs and probably look at the source code.
If you show you did a little research already,
and ask a suitably geeky technical question, and address it to the right people,
perhaps the authors of the plugin themselves (as well as cc to the list of course!)...
....then you are much more likely to get an informative answer!
A general question like yours might often get ignored... I'm answering it as I also have an interest in such things...
but i don't know the answer either.
You need to grab the interest of someone that does...

am I the only one that finds the statement
"Thanks in advance"
a little off colour... perhaps slightly presumptuous?
Answers on a postcard to:
"Over sensitive software developers club"

anyway,
I hope someone can help you more than I did...
coz its an interesting question.
cheers
