Subsurface scattering.
These light interactions are dominated by subsurface-scattering effects inside the individual grains. For this reason, the visual appearance of a granular mixture is not only defined by the outermost layer of grains but by the whole ensemble. In computer graphics, synthesizing photo-realistic images is a key challenge. We encounter granular ...
Screen-Space Subsurface Scattering strikes a balance between speed and quality, which makes it a good, yet not perfect, solution for real-time rendering. For example, it will fail to compute light info when there are materials occluding the target material.

In the pursuit of generating ever more realistic scenes, it is a phenomenon which must be incorporated into rendering frameworks.
The main sampling operation that must be provided by implementations of the BSSRDF interface, BSSRDF::Sample_S (), determines the surface position where a ray re-emerges following internal scattering. Low density 1 Medium density 2 High density 3. Figure 15.7: Subsurface Scattering from the Dragon Model Rendered Using Different Material ... Subsurface Scattering. Subsurface Scattering handles light that penetrates and moves within the area under a surface. Use it to make organic materials, like skin, look smooth and natural rather than rough and plastic-like. HDRP implements subsurface scattering using a screen-space blur technique. Subsurface scattering is ubiquitous in digital worlds created for films. While diffusion-based approximations are still widely used, they can produce undesirable and implausible results when the "semi-infinite slab" assumption is violated.
Screen-space subsurface scattering is currently the most common approach to represent translucent materials in real-time rendering.

Inverse Scattering. The common cause of the characteristic appearance of translucent materials is sub-surface scattering: As photons reach the surface of a translucent object, they continue traveling in its interior, where they scatter, potentially multiple times, before reemerging outside the object.

For this reason, subsurface scattering is also called subsurface light transport. Most semi-transparent materials exhibit a certain degree of ...
Subsurface scattering mean free path distance (mfpd). This specifies how far the light travels inside an object and as a consequence how smooth the subsurface scattering is. This gets multiplied by the unit length set in the Properties section. Higher amounts make the object appear less opaque and more translucent as well as increase noise.

We derive explicit formulas for backscattering and transmission that can be directly incorporated in most rendering systems, and a general Monte Carlo method that is easily added to a ray tracer. ... Subsurface Scattering . The Subsurface Scattering node is used to add simple subsurface multiple scattering, for materials such as skin, wax, marble, milk and others. For these materials, rather than light being reflect directly off the surface, it will penetrate the surface and bounce around internally before getting absorbed or leaving the surface at a nearby point.
