Hi all,
I have a problem...I hade to write a new interactor style to move an abject (a cone) by another dataset. I want to create a this cone in the "display area" and then start my new interactor style and let move my cone... I can I do this?!
my biggest problem is to create this cone in the display area so  it can move (like a trasform filter) in another image previously  opened.
thanks in advance
