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.
