Geodesic coefficient. To what it can evolve?

[alexichepura]

Currently I calculate geodesic coefficient and use it once for the whole scene:

This approach works for small, city like locations.
But it will not work for bigger scenes, continuous navigation or even globe.
I believe there are known approaches to this.
