Fields

Field	Description
MaximumOrder	Retrieves the maximum order for SH evaluation.
MinimumOrder	Retrieves the minimum order for SH evaluation.

Methods

Method	Description
Add	Adds two SH vectors together; in other words, Out[i] = A[i] + B[i].
Dot	Computes the dot product of two SH vectors.
EvaluateConeLight	Evaluates a light that is a cone of constant intensity and returns spectral SH data.
EvaluateDirection	Evaluates the SH basis functions from an input direction vector.
EvaluateDirectionalLight	Evaluates a directional light and returns spectral SH data.
EvaluateHemisphereLight	Evaluates a light that is a linear interpolation between two colors over the sphere.
EvaluateSphericalLight	Evaluates a spherical light and returns spectral SH data.
ProjectCubeMap	Projects a function represented on a cube map into SH.
Rotate	Rotates the SH vector by the given matrix.
RotateZ	Rotates the SH vector in the z-axis by the given angle.
Scale	Scales a spherical harmonic (SH) vector, in other words, Out[i] = A[i] * Scale.
