Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method for rendering rainbows realistically based on atmospheric optical

phenomena. Taking into account wave optics, we can render supernumerary rainbows and rainbows with

different radii of raindrops. In addition, our method displays scattering phenomenon of light and

changes color of rainbows according to the solar elevation. We also consider the distribution of rain

drops. Moreover, we improve the method to be able to consider in-scattering effects. Considering the

in-scattering effects, our method can render the color of sky and rainbows influenced by the sky

color.
