Are you asking this because you don't have Version 6 and are thinking of 
getting it?

In any case, with Version 6 any piece of Graphics3D, including that produced 
by ParametricPlot3D, can be rotated with the mouse. You can also hold down 
the the Ctrl key and zoom in and out with the mouse. You can also hold down 
the shift key and translate the image back and forth or up and down.

It is also possible to produce animations or Manipulate statements where one 
uses Rotate or RotationTransform to rotate an image within the bounding box.

If the image has a high degree of detail, the action may be slow, but many 
images rotate almost instantaneously.
