Rayleigh scattering USELESS @ daytime-border❚Green exclusion❟@sky sunrise&sunset❚VS. prismatic model

•evenings and mornings of day❟ clouds (A.–highlighted without green contrary to the prism)

•generally sun simulators excluded – cannot find any sun-sim in Poland

A.[my clouds collection]

•but from LuxCore Render phys. „correct”:

–––– The old Rayleigh scattering is a stereotypic – very very selective function/equation that completely omits daytime-border situations. The thumb images don’t contain green color in the whole pallette of its colors! A contrario, the prism optical dispersion of white (for example, solar) light does generate it.

•••Some Blender project details: simple scene, BiDir rendering on 1-core 1.8GHz CPU lasts approx. 1.5h

— — … Mie scattering (as linked to show some old scientific background) doesn’t matter ALSO – in fully the same way.

Model describes std. circumstances, not polar (that we’ve some basis to believe in 2 holes at N&S poles – but… Earth is not hollow NOR empty…). Everything shows that it is Concave.
