It allows camera movement to be controlled independantly of anything else your doing at a particular time, at a (generally) regular time. It doesn't slow your main program down as the plug-in does all the hard work.
Take for example the Halo title sequence. Usually in the standard way you would have something like :
repeat
move the camera,
move the mouse
until mousebutton pressed
However now (thanks to moi), you can do something akin to :
setup camera movement
repeat
move the mouse
until mousebutton pressed
Reducing what you need to do in any routine.
The place for all
great plug-ins
