RE: (17B) (19B) (27S) Percentage of Sphere's Surface Visible for Height Above Surface
For a negative height, the simple formula will give a negative percentage visibility, but I have no idea how that should be interpreted geometrically!
I only posted the formula because it turned out to be so simple and elegant compared to how I was expecting it to turn out. — Ian Abbott |
