| 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. |
