In computer graphics, a bidirectional reflectance distribution function (BRDF) is used to model light reflectance properties at a surface, and is defined as the ratio of the radiance (incident light) ...

A new optical method that can image subsurface structures under skin has been demonstrated by scientists at NIST and the Johns Hopkins University Applied Physics Laboratory. The method was ...

The surface of rendered objects in computer games often looks unrealistic. A new method creates much more realistic images, imitating the complex scattering processes under the surface. The surface of ...

It hasn't been hard to produce realistic-looking skin in computer-generated movies, but it's much harder to do that in the context of a game running live on your console or PC. That trip to the ...
