Abstract

This paper proposes an efficient technique for rendering a scene with participating media. To render a scene with participating media, radiance at many sample points should be calculated. In our method, we first approximate the in-scattered radiance. Then, by using the precomputed radiance values, importance sampling method is used to render a high quality image.
