Hi All,

A few days ago Monte Ramstad wrote:

<<If your printer has just enough resolution to print a two image

image, then you could produce a lenticular print of a stereo pair.  The
problem is that the spacing of your eyes typically won't be wide
enough to be able to view the centers of the left and right vertical
strips
simultaneously.  Therefore if you try to position your head to view the
stereo pair, you will see a lot of the opposite image in each of the
views.

In order to cleanly separate the two views, your printer should be
capable
of printing many more views (possibly as many as 10) even if you only
decide to use two views.>>

This could cause me problems, since I'd assumed I could get away with three
stripes per lenticule.  Using 57 or 75 lpi lenticular screens I could just
about double that and still have some dots available for dithering.  (My
Epson 870 is *claimed* to have 1440dpi horizontally, but don't take it too
seriously.)  However, I have three images from my IT wizard, so I'd end up
looking at a pseudoscopic image if I held the print square on wouldn't I? 
That's assuming I printed  right, centre, left, right, centre, left for
each lenticule.

There are obviously subtleties that I hadn't appreciated here.  Monte, can
you give me some pointers on how to estimate how many images I need?  Or
just some indication of where to look?  If you think it would stray too far
into tech-3dterritory for this list then off-list would be fine.  I'm not
on tech-3d at present.

TIA,


Dave Spacey
