Subsurface scattering is a type of light transport that occurs when light penetrates the surface of an object and scatters beneath the surface. This can lead to a number of visual effects, such as soft shadows, blurry reflections, and translucent surfaces.
In 3D visualization, subsurface scattering is often used to create realistic skin or fabric textures. By simulating how light interacts with these materials, artists can create digital assets that look and feel more lifelike.
While subsurface scattering is a complex topic, understanding the basics can help you create more realistic renderings in your own work.
