egghead stereo??

!!!  Alternatively, you can describe
!!!  stereo viewing as the motion of a
!!!  single eye from one side of
!!!  your nose to the other at infinite speed!  

TIMEOUT!!!
People are reading this stuff, you know!!!

This has been a very interesting thread, starting with an observation
that must be a quote, 'perception follows geometry'.
The study of perspective in art concerns this, and its corollary,
geometry follows perception.  There are wonderful books on da Vinci
that deal with this subject, and the medieval "discovery" of perspective.

>From thence, the discussion led to distortions seen when video cameras
are 'toed-in'.  It was noted that similar discomfort results from distortions
seen in monocular films, when the camera is panned across a scene in a 
way that could not be done by a moving observer.  Some of the aspects of
stereoscopy that are hard to understand have 'flat' counterparts.
Discomfort when viewing stereo might be from monocular distortions.

Things got muddy when the notion of monocular stereo at unbelievable
velocities was proposed.  To get one eye around a nose like mine would
take hyper-luminal velocities, and my hard disk crashed.

These topics deserve amplification, and these questions will be asked more
cogently at some earlier hour of the evening.

It was noted that the video in question was by A. Woods.  I have been
wondering if he (or any reader) attended the Jan/Feb 96 SPIE Conference.
 I noted on a web page (Woods' or SPIE's,) a scheduled paper on stereoscopic
X-rays.  I have not been able to get back to that page, and am consumed with
curiosity as to the relevant events at the conference.
