What does sub surface scattering do?
Subsurface scattering (SSS), also known as subsurface light transport (SSLT), is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits the surface at a different point.
What things have subsurface scattering?
Human/animal skin, the skin of grapes, tomatoes, fruits, wax, gels (like honey, or Jello) and so on all have subsurface scattering (SSS), and photo-realism really cannot be achieved without it.
How is subsurface scattering related to direct surface scattering?
Direct surface scattering (left) plus subsurface scattering (middle) creates the final image on the right. Subsurface scattering ( SSS ), also known as subsurface light transport ( SSLT ), is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits
How to draw a mesh with subsurface scattering?
Draw the mesh for real using the camera’s projection matrix, then in the pixel shader sample the convolved irradiance maps and apply the diffuse albedo map to get the diffuse reflectance with subsurface scattering. Obviously their results speak for themselves in terms of quality, so I don’t think that would be the main issue preventing adoption.
How is subsurface scattering a mechanism of light transport?
Subsurface scattering (SSS), also known as subsurface light transport (SSLT), is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material
Who was the first person to use subsurface scattering?
Eugene d’Eon and David Luebke were able to show that it could also work in real-time on (at the time) high-end GPUs, and in the process they were able to create some visuals that are still impressive today.
