parallax (countable and uncountable, plural parallaxes)

1. An apparent shift in the position of two stationary objects relative to each other as viewed by an observer, due to a change in observer position.
   • 1685, J. Flamsteed, Philosophical Transactions, XV, p. 1217:

     […] Heliocentrick places, to which the Parallaxes being applied, give the Geocentrick.

     Planes farther back on the z-axis scroll more slowly than those in front of them, producing a parallax effect. Early games with parallax scrolling tended to have their action taking place all in the forefront plane […]
