That's right.

Here what you want to do is to divide your rendering into pieces, for
example having 3 cameras with a 60 degree FOV each.  You do not specify
which kind of display device(s) you have, but I suppose you have two or
more monitors.  There are examples in the source code for creating the
slave cameras and displaying each one of them i a different screen.
