<br>
I want to use scroll wheel down for Pan in my interactor instead of a modifier key. What’s the best way to do this? I don’t see how to get it in an interactor style and if I add a PanManipulator it seems to take over all the mouse handling.<br>
<br>
What’s the relationship between an interactor and a manipulator?<br>
<br>
Thanks<br>
