TL;DR: This paper shows how Metropolis Light Transport can be extended both in the underlying theoretical framework and the algorithmic implementation to incorporate volumetric scattering, and introduces a new mutation strategy that is specifically designed for participating media.
Abstract: In this paper we show how Metropolis Light Transport can be extended both in the underlying theoretical framework and the algorithmic implementation to incorporate volumetric scattering. We present a generalization of the path integral formulation that handles anisotropic scattering in non-homogeneous media. Based on this framework we introduce a new mutation strategy that is specifically designed for participating media. Our algorithm includes effects such as volume caustics and multiple volume scattering, is not restricted to certain classes of geometry and scattering models and has minimal memory requirements. Furthermore, it is unbiased and robust, in the sense that it produces satisfactory results for a wide range of input scenes and lighting situations within acceptable time bounds.

TL;DR: In this article, the authors proposed to reduce the loss of the quantity of a light with thin device and a small wattage of light source and to obtain a light diffusing effect of good uniformity by forming most of a base material with a transparent layer and forming a light diffusion exit face side, and an intermediate layer whose property is optically intermediate between properties of the diffusing layer 3 and the transparent layer 2 is formed between the diffuser layer 3, and a reflection layer with a silver thin film layer.
Abstract: PURPOSE:To reduce the loss of the quantity of a light with thin device and a small wattage of a light source and to obtain a light diffusing effect of good uniformity by forming most of a base material with a transparent layer and forming a light diffusing layer on one surface and forming an intermediate layer whose property is intermediate between the transparent layer and the light diffusing layer and forming a reflection layer with a silver thin film layer. CONSTITUTION:Most of a base material 1 consists of a transparent layer 2, and a light diffusing layer 3 is formed on its surface, namely, the light diffusion exit face side, and an intermediate layer 4 whose property is optically intermediate between properties of the diffusing layer 3 and the transparent layer 2 is formed between the diffusing layer 3 and the transparent layer 2. Light in the transparent layer 2 is diffused and projected from the exit face to the outside of the base material 1 more satisfactorily than the absence of the intermediate layer 4. A reflection layer 5 is formed on the rear face of the base material 1, and light sources 10 and 11 are arranged along end faces 8 and 9, and end faces other than end faces facing light sources 10 and 11 are subjected to the light scattering reflection treatment, and thus, the luminance is improve about 1.5-1.8 times as high as an aluminium light diffuser with the thin device and a small wattage of light sources without changing the shape.

TL;DR: The numerous small angle scatterings of the photon in the direction of the incident beam are followed accurately and produce a greater penetration into the cloud than is obtained with a more isotropic and less realistic phase function.
