Stereo Window, the Screen Plane and Negative, Zero or Positive Parallax
Simply put, the "Stereo Window" refers to the physical display surface. You will be able to visualize the
concept if you think of your TV screen as a real window that allows you to view the outside world. 
Objects in your stereoscopic scene can be behind or outside the window (positive parallax,) on the
window (the Screen Plane or zero parallax,) or inside, between you and the window (negative
parallax.) In the same way objects appear in different horizontally offset locations on our retina to
create parallax separation, stereoscopically recorded and displayed objects will appear to have
different horizontal offsets (parallax) depending on their depth in the scene. If an object has no
perceivable amount of parallax then we consider it to appear on the screen surface just as the star in
the illustration. This is why converging on an object will make it appear to be at the screen. This can
be done by converging the cameras on the objects while shooting, or by sliding the images
horizontally in opposite directions during post production.
This is the basic principle behind stereoscopic shooting and emulating human binocular vision with
two cameras.
