output System.Single[]
An array of floating point values that represent SH output coefficients.
order System.Int32
Order of the SH evaluation. Must be in the range of SphericalHarmonics.MinimumOrder to SphericalHarmonics.MaximumOrder, inclusive. The evaluation generates order2 coefficients. The degree of the evaluation is order - 1.
angle System.Single
Rotation angle in radians. The rotation is performed around the z-axis.
input Microsoft.DirectX.GraphicsStream
A GraphicsStream object that represents rotated SH coefficients.


Each coefficient of the basis function Ylm is stored at location l2 + m + l, where:

  • l is the degree of the basis function.
  • m is the basis function index for the given l value and ranges from -l to l, inclusive.
