CloseSpherical harmonics up to the second order (3 bands, 9 coefficients).
Spherical 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.

this[int,int] | Access individual SH coefficients. |
AddAmbientLight | Add ambient lighting to probe data. |
AddDirectionalLight | Add directional light to probe data. |
Clear | Clears SH probe to zero. |
operator != | Returns true if SH probes are different. |
operator * | Scales SH by a given factor. |
operator + | Adds two SH probes. |
operator == | Returns true if SH probes are equal. |
