P3D Re: Lenticular Optics

[gecko <gecko@xxxxxxxxxx>]

I've just created my first few home-made lenticular images.  So far,
I've only been able to create 2-image lenticulars (3D and flip-type).
Two problems I've found from 2-image-only lents...

1.  "The sweet spot".  Using 2-images, there's a limited sweet spot for
your eyes to pick up the 3D effect.

2.  Using more images creates less "scintillation" or image-to-image
'jump', and using more images allows more 3D images to be viewed (ie,
for 3 images you get 2 stereo pairs, and for a 4-image lent, there are 3
stereo pairs)
