설명

Spherical 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.

변수

this[int,int]Access individual SH coefficients.

Public 함수

AddAmbientLightAdd an ambient light to the spherical harmonics.
AddDirectionalLightAdd a directional light to the spherical harmonics.
ClearClears the spherical harmonics coefficients to zero.
EvaluateEvaluates the spherical harmonics for each given direction. The directions and results arrays must have the same size.

연산자

operator !=Returns true if the spherical harmonics are different.
operator *Scales SH by a given factor.
operator +Adds two spherical harmonics.
operator ==Returns true if the spherical harmonics are equal.
