Enhanced Ray Tracing

Rendering the interaction between light and microscopic particles in a scene, such as smoke or floating dust, has traditionally been a computationally intensive and difficult process. To produce an accurate rendering requires simulation, or reasonably accurate approximation, of how the light interacts with these particles on a fine level of detail. Specifically, when light enters an area of some participating media, it will travel until it hits a particle, then it is scattered in another direction and travels until it hits another particle, where it is scattered again, until the light escapes the media.
