Others have suggested OSG_WINDOW, but you can also pass --window x y w h
on the command line. Most of the time when testing I will add
-- window 50 50 1024 768
so I get a nice window instead of fullscreen.

You can use OSG_SCREEN x for a single fullscreen viewer on screen x, or
if you're using osgViewer::Viewer you can call
setUpViewOnSingleScreen(x) to get the same effect, as Paul said.
Note that currently, on Vista, when using that method (or OSG_SCREEN),
you will get the fullscreen view on screen x, and your other screen(s)
will be black. This is a bug resulting from the new Vista driver model,
which should be fixed. I'm just waiting to get a bit of time from our
tight deadlines to help fix it. On XP it works properly (there is a
fullscreen viewer on screen x and nothing on the other screen(s), i.e.
you see your other windows and the screen(s) don't turn black).
So to summarize:
osgviewer with no command line arguments and no env variables is the
same as osgViewer::View::setUpViewAcrossAllScreens().
osgviewer with either OSG_WINDOW x y w h in the environment or --window
x y w h on the command line is the same as
osgViewer::View::setUpViewInWindow(screen, x, y, w, h) where screen will
be 0 by default or OSG_SCREEN if set.
osgviewer with OSG_SCREEN x in the environment (there should probably be
a command line argument for this too) is the same as
osgViewer::View::setUpViewOnSingleScreen(x).
So if you ever want to do custom window setups for your app, looking at
the source of the above methods is a great help. Also note that if
you're using osgViewer::CompositeViewer, when you create a new
osgViewer::View to add to it you can still call these methods as quick
shortcuts to get some standard window setup. It's a good design!
A little plug for Paul's book: while typing this up, I was looking up
the env vars in the OSG Reference Manual v2.2 :-)
Hope this helps,
J-S
