No!  Just render the left eye, move the camera about 6cm to the right
and render the right eye.  Don't change anything else!

You don't need to do anything to PLIB - I have written dozens
of applications that do stereo this way - both with LCD shutter
glasses and Red/Cyan glasses.  Just clear the screen - then
call ssgCullAndDraw twice with appropriate switching of buffers
or colour masks between the two calls.

That is assuming you are using glasses with screens that are
in the same plane.

If you are using some hideously expensive pair of head-mounted
displays with the two displays pointing off in different directions
then you need more complex advice (which I can give you - because
we work with these things all the time where I work).

A modern example can be found in http:botZilla.sf.net which has
a red/cyan glasses option.
