What is wrong with the other replies??

In Mathematica 6, graphics can be parts of arbitrary expressions.  So, 
as I already suggested, type the following around your plot

Options[<graphics go here>, ViewPoint]

Or if you want to see the ViewPoint value in real-time as the graphics 
are rotated, use the Dynamic[] method suggested by others.
