Vector3.TransformNormal(Vector3,Matrix) Method (Microsoft.DirectX)

  • Article

Transforms a 3-D vector normal by the given matrix.

Definition

Visual Basic Public Shared Function TransformNormal( _
    ByVal source As Vector3, _
    ByVal sourceMatrix As Matrix _
) As Vector3
C# public static Vector3 TransformNormal(
    Vector3 source,
    Matrix sourceMatrix
);
C++ public:
static Vector3 TransformNormal(
    Vector3 source,
    Matrix sourceMatrix
);
JScript public static function TransformNormal(
    source : Vector3,
    sourceMatrix : Matrix
) : Vector3;

Parameters

source Microsoft.DirectX.Vector3
Source Vector3 structure.
sourceMatrix Microsoft.DirectX.Matrix
Source Matrix structure.

Return Value

Microsoft.DirectX.Vector3
A Vector3 structure that contains the results of this method.

Remarks

This method transforms the vector normal (x, y, z, 0) of the source vector, or the array of vector structures, by the sourceMatrix matrix.

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.
