UnsafeNativeMethods.Vector3.TransformNormalArray(Vector3,Int32,Vector3,Int32,Matrix,Int32) Method (Microsoft.DirectX)

  • Article

Transforms array (x, y, z, 0) by a given matrix.

Note: For programming in Microsoft Visual Basic .NET or Microsoft JScript .NET, use the equivalent method in the Microsoft.DirectX structures.

    Vector3 pSource,
    int vectorStride,
    Matrix pSourceMatrix,
    int count
);
C++ public:
static Vector3 TransformNormalArray(
    Vector3 pOut,
    int outStride,
    Vector3 pSource,
    int vectorStride,
    Matrix pSourceMatrix,

);
JScript public static function TransformNormalArray(
    pOut : Vector3,
    outStride : int,
    pSource : Vector3,
    vectorStride : int,
    pSourceMatrix : Matrix,
    count : int
) : Vector3;

Parameters

pOut Microsoft.DirectX.Vector3
A Vector3 structure that is the result of the method.
outStride System.Int32
Stride between vectors in the output data stream.
pSource Microsoft.DirectX.Vector3
Source Vector3 structure array.
vectorStride System.Int32
Stride between vectors in the input data stream.
pSourceMatrix Microsoft.DirectX.Matrix
Source Matrix structure.
count System.Int32
Number of elements in the array.

Return Value

Microsoft.DirectX.Vector3
A Vector3 structure that is the result of the method.

Remarks

This method transforms the vector normals (x, y, z, 0) of the pSource parameter by the matrix pSourceMatrix.

If you transform a normal by a non-affine matrix, the matrix you pass to this function should be the transpose of the inverse of the matrix you would use to transform a coordinate.

The return value for this method is the same value returned in the pOut parameter. This allows you to use the TransformNormalArray method as a parameter for another method.
