Realistic Solar Disc Rendering

Abstract

This paper concentrates on rendering the solar disc considering Rayleigh scattering, Mie scattering, absorption, and refraction. The atmosphere is modeled in layers, each layer having a set of individual optical properties. Based on di erent atmospheric temperature pro les and climates, the solar disc is rendered in realistic shape and color. In particular, we replicate optical phenomena such as the red and the green ash, limb darkening, and refractive distortions of the solar disc.
