🌈 Iridescent Cloud Corona: Mie Diffraction by Droplets, Ring Radius vs Droplet Size and Mother-of-Pearl Colour in 3D

Look up at thin cloud near the Sun in a 3D English meadow and watch coloured rings appear. Change the droplet size, size spread, cloud thickness, Sun or Moon, and compare exact Mie theory with the Airy diffraction approximation.
