Demo of new .eyeNwidth sysvars

EricL:
Simple example illustrating the new ability to change the width of the field of view for each eye.

Testlund:
Hmm... If I understand this correctly the bot get a better sense of the size and position of the object it's looking at? If so, then it whould be better if it could spread it's vision slightly wider to see all of the object.

Numsgil:
Very nice.  Alot of possibilities open up.

EricL:
The gene above is mearly illustrative.  Given the sight distance and average bot width, there probably isn't much of a need to narrow the width of the eyes beyond perhaps 5 or so (-29 .eyeNwidth store) in real bots though you never know....  The concept is that by narrowing the field, you get better resolution about the exact bearing of far away objects and also can look past nearby objects to see far ones if you want.  The image below illustrates this.  I changed the gene to make each eye absolute width 5.  Note that the bot can look past the near and focus on the far one, which would otherwise show up in a bunch of eyes and maybe even in .eye5 if the eye widths weren't narrowed.  With it's vision narrowed, the refvars will be representitive of the far bot, not the near one.

Henk:
This is nice  It is quite drastic though, I imagine evo-bots can get pretty messed up with mutations involving these sysvars, and I've already witnessed what waste can do to a bot if a random value is stored in any of these sysvars.

I imagine this isn't very backwards compatible(ie bots that don't know about this can get messed up pretty bad), or am I wrong?

(not that I'm against these features, I luv em  )
