Subsurface scattering is a phenomenon in computer graphics that simulates the behavior of light as it interacts with translucent or semi-translucent materials. It refers to the scattering of light beneath the surface of an object, resulting in a soft and diffused appearance.
When light interacts with a translucent material, such as human skin, wax, or marble, it penetrates the surface and scatters within the material before being partially absorbed or exiting the surface again. This scattering process causes the light to travel through multiple layers of the material, resulting in a diffusion of light and a softening of the object's appearance.
In computer graphics, subsurface scattering is simulated by using complex algorithms and mathematical models. These models take into account the physical properties of the material, such as its thickness, density, and scattering coefficients, to accurately calculate the behavior of light within the object.
By incorporating subsurface scattering into computer graphics rendering, objects can appear more realistic and natural. For example, when rendering a human face, subsurface scattering can simulate the way light interacts with the layers of skin, resulting in a more lifelike and believable representation.
Overall, subsurface scattering is an important concept in computer graphics as it allows for the realistic rendering of translucent materials, adding depth and realism to virtual objects and characters.
