We show how to distribute samples along a ray proportionally to the incoming radiance for point and area lights. In heterogeneous media, we decouple ray marching from light calculations by computing a representation of the transmittance function that can be quickly evaluated during sampling, at the cost of a small amount of bias.

Abstract. We introduce a set of robust importance sampling techniques which allow efficient calculation of direct and indirect lighting from arbitrary light sources in both homogeneous and heterogeneous media. We show how to distribute samples along a ray proportionally to the incoming radiance for point and area lights.

Abstract. In this paper we show how bidirectional path tracing can be extended to handle global illumination effects due to participating media. The resulting image-based algorithm is computationally expensive but more versatile than previous solutions. It correctly handles multiple scattering in non-homogeneous, anisotropic media in complex illumination …

C. Kulla & M. Fajardo / Importance Sampling Techniques for Path Tracing in Participating Media We will first highlight some cases where classical sam-pling methods can fail, then show how to distribute samples proportionally to incoming radiance along the ray in a way that avoids the weak singularity from the geometric term.

A practical path guiding method for participating media
https://link.springer.com/article/10.1007/s41095-020-0160-1
Rendering translucent materials is costly: light transport algorithms need to simulate a large number of scattering events inside the material before reaching convergence. The cost is especially high for materials with a large albedo or a small mean-free-path, where higher-order scattering effects dominate. In simple terms, the paths get lost in the medium. …
Volumetric path tracing - Wikipedia
https://en.wikipedia.org/wiki/Volumetric_Path_Tracing
Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire, explosions, smoke, clouds, fog or soft …

Volumetric Path Tracing
https://justgood.dev/docs/740-paper.pdf
This process is called path tracing. This generally gives us good results, and allows us to model scenes involving glass (caustics, specular highlights, etc) and mirrors. However, the actual path that light travels to hit your eye can alter the color as well. This is called a volume interaction, and we model this using participating media.
