[EM] Yee/B.Olson Diagrams (YBD's): the next step

[Raph Frank]

Ultimately, there are more degrees of freedom than a 2d picture can
show.  If you hold one of the candidates fixed and let the other two
be placed anywhere, then you have four degrees of freedom.  However,
one of those degrees of freedom can be dropped due to rotational
symmetry.

This gives the same 3 degrees of freedom as Forest's 2d + scale method.

On my implementation at
http://ivnryan.com/ping_yee/results.html

I have some user control.  The user can place the centre of the
population at any point and then the winners are highlighted.  This
was mainly for multi-seat competitions.

In the single seat versions, it will highlight the single winner and
shows 2 circles (enclosing 95% of the population and 50% of the
population)

Something similar could be done for Forest's idea.  There could be 2
pictures side by side.  The one on the left would show all the
configurations and the one on the right would show the 'current'
standard diagram.  When you move the mouse to a position on the left
diagram, it would update the right hand diagram so that it shows the
candidate positions for that configuration and the strandard Yee
diagram.

There would also need to be some way to adjust the scale.

In principle, one way to show the 3d effect would be to have 3d 'fog'
where there colour matches the pathology.  If the user could rotate
the fog, it would give an impression of the confguration.  The other
option is to just have say 10 scale settings that can be used.

One other potential problem is that it would require considerably more
computer time.  Each pixel would require as much time as an entire
standard diagram.  Also, there would need to be some way to
automatically determine if a diagram has a given pathology.
