Crude letters should spells out my last name, "Lansey"

When I was little I spent some time to figure out why we have depth perception.  Naturally, when I came across a stereoscopic photo, I became interested in the invention.  Since I already knew how we see in 3D, it wasn't hard to see how the stereograms worked.  I even drew some crude stereoscopic pairs on graph paper.

Magic Eyes were much more complicated to figure out because I had no idea how they were created.  With stereoscopic photos, I knew they were taken with a camera with two lenses spaced about the distance between two eyes, exposing two photos.  To me a magic eye was a huge unordered mush.  One of my families books though, had a couple relatively simple ones on the first couple pages.  It took me some time, but by tenth grade, I had worked it out. 

I was in the middle of making a 3D guitar "masterpiece" when then the headaches came on so I quit working on it. 

A cousin of mine is related one of the original magic eye developers.  He has explained to me how to make a program to do this.  I plan to write this program the second I have learnt enough to do it.

Stuff to notice:

  • The distance between the eyepieces on some fancy Binoculars is considerably less than the distance between the big lenses out front (see diagram). 

    This exaggerates depth perception greatly.  Pay attention next time you look through one of these contraptions.

 

 

Before Photoshop.  notice the height changes in steps.


I avoid the steps problem in this kind of picture.
