Karl Wright commented on LUCENE-8066:
-------------------------------------
[~ivera], basically all you did was get rid of the backing plane that I added
to deal with the situation where the circle becomes concave. I honestly don't
know how that could work. Otherwise it looks identical (functionally) to the
existing code. Why do you think the backing plane was unnecessary?

> Hi [~daddywri],
> I was thinking in the limitation of convexity for circle planes and I worked
> out another approach that overcome this limitation. There is a condition,
> circle lanes must contain the center of the circle which is probably always
> true for planets like WGS84 which are not too far from the sphere.
> The idea is create a short of polygon for every slice using the center of the
> circle (like an orange) and therefore you can treat them separately. I
> attached what I developed, it seems to pass all tests regardless of the
> radius.
> Let me know what you think and if I am missing something.
