Sphere harmonics lighting
http://scipp.ucsc.edu/~haber/ph116C/SphericalHarmonics_12.pdf WebSpherical harmonics (SH) represent a function or signal over directions, and are commonly used in computer graphics to efficiently evaluate smooth lighting. Unity uses them for LightProbes and environment lighting. L2 spherical harmonics is composed of 9 coefficients for each color channel.
