Yes, a majority of computer graphics have z-axis information in the program
that is not used stereoscopically, but could be.  With so-called 3-D
graphics, the z-axis is used primarily for perspective and to permit
rotations (wear your Pulfrich glasses).

Obviously, since it works for Pulfrich, you could use this time parallax for
stereoscopic extraction.
