Because we can ordinarily cross our eyes much further than we can diverge them, we can present
much larger images on a Web browser in eye-crossing than in diverging stereoscopy.
 
 
 
 
 
 
 

This four-petal trillium was at the Tryon State Park Trillium Festival this year.
I've place the blossom in front ot the window and the leaves about at the window.

The Old Maid's Bloomers (Delicate Arch to NPS)
Arches National Park (National Monument when the picture was taken)

With this very great depth from arch to far ridges, the binocular rivalry
is a bit much if the window is placed near the arch.

In this eye-crossing pair, I placed the window.at about the ridge in the near distance.
That places the arch well in front of the window.  The larger images allowed by eye-crossing
allows more detail in Web-based displays.

A ball-and-stick model of silicon.
Looking down the [110] direction.
From a series of stereo photos taken in 1955 at Hughes (Aircraft Co) Semidonductor materials research laboratory.

.The picture was taken to be projected onto a aluminum screen for polaroid viewing.
The images were mounted to place part of the model well in front of the screen.

Grand Teton and Mt Owen
(or is that Teewinot)

.This was taken to illustrate the "See Like a Giant" principle.
It's to show how much additional information for route finding can be
obtained by using wide-based stereo pairs.

Ball-and-stick crystal model
Simple cubic space lattice

Stereopsis results because the view of an adjacent cell is the same
as the view of the cell itself but from a slightly different angle.
