You are very welcome.
I would suggest using scaling for zooming in both perspective and parallel
projection modes. You are correct, it would be too involved to switch
between the two methods and by sticking with one method it would be
consistent. In fact, using translation for perspective and scaling for
parallel could cause some unexpected results when switching between the two
modes.

Thanks Joe. Yes, scaling to mimic zooming in z-direction
is a viable option. But, if the middle-mouse-button(MMB) already
is dedicated to the task of zooming, I am wondering if it wouldn't
get a little too involved to change the MMB task to scaling
when the user has switched mode to parallel from perspective ?
Any further thoughts would be appreciated.
