[tech-3d] Re: Stereo Base Calculation, Carrolleschery

Achilles: Hi, Tortoise! Tortoise: Hi, Achilles! I'm going to make a 
stereopicture. I'm computing the optimum stereobase. My camera lens
focal length is  35 mm,  so the optimum deviation should not be 
over 1.2 mm,  but certainly should be more than zero.
I have The Only Formula That Never Breaks Down, and The Spreadsheet
coming with it, but what deviation shall I put in? 
A: I've brought today my deviation equation, an old, maybe obsolete 
formula, but we can try it. T: Great!, I first turn on my phonograph.

T: So let's calculate  the stereobase with the formula
that never breaks down.  Let's put in focal length, far
point distance and near point distance.  What deviation 
should I use as input ?
A: Well,  we know that  it should be somewhere between
zero and 1.2 mm,  but let's use my old, maybe  obsolete
equation to calculate  deviation.  We just put in focal 
length, far point distance, near point distance and the
stereobase. The first three of those values we have got
only the stereobase is missing.
