P3D stereogram infinity

["ron labbe" <ron@xxxxxxxxxxxx>]

Larry has an interesting point:

>*****  It's true that a typical stereogram is built in front of a
background
formed by the tiled (repeating) pattern, but it's *not* true that infinity
is at the window!

Again, it's hard to define the window with an single image random dot
stereogram.

> The background of a stereogram is usually considered to
define infinity for each image.  Infinity normally is defined by precisely
parallel lines extending outwards from each of the viewer's eyes, or the
average interocular distance. A parallel mode stereogram MUST have a maximum
pattern repetition distance that is equal to or smaller than the average
interocular because anything larger and most people wouldn't be able to view
it.

Exactly- so stereogram "parallel" is not parallel. Larry, you would not
argue that it is impossible to have a regular parallel STEREO PAIR (where
the window IS precisely defined) with infinity at the window... would you?

A very interesting argument, indeed.
