SphericalHarmonics.Add Method

Language:

Note: This documentation is preliminary and is subject to change.

Adds two spherical harmonic (SH) vectors together; in other words, Out[i] = A[i] + B[i].

Definition

Visual Basic .NET Public Shared Sub Add( _
    ByVal output As GraphicsStream, _
    ByVal order As Integer, _
    ByVal vectorA As GraphicsStream, _
    ByVal vectorB As GraphicsStream _
)
C# public static void Add(
    GraphicsStream output,
    int order,
    GraphicsStream vectorA,
    GraphicsStream vectorB
);
Managed C++ public: static void Add(
    GraphicsStream *output,
    int order,
    GraphicsStream *vectorA,
    GraphicsStream *vectorB
);
JScript .NET public static function Add(
    output : GraphicsStream,
    order : int,
    vectorA : GraphicsStream,
    vectorB : GraphicsStream
);

Parameters

output Microsoft.DirectX.GraphicsStream. A GraphicsStream object that represents the output coefficients.
order System.Int32. Order of the spherical harmonic (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.
vectorA Microsoft.DirectX.GraphicsStream. A GraphicsStream object that represents the first spherical harmonic (SH) vector to add to the second vector.
vectorB Microsoft.DirectX.GraphicsStream. A GraphicsStream object that represents the second spherical harmonic (SH) vector to add to the first vector.

Remarks

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