Vector3.TransformNormal Method

Language:

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

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

Definition

Visual Basic .NET Public Shared Function TransformNormal( _
    ByVal vector() As Vector3, _
    ByVal sourceMatrix As Matrix _
) As Vector3()
C# public static Vector3[] TransformNormal(
    Vector3[] vector,
    Matrix sourceMatrix
);
Managed C++ public: static Vector3 TransformNormal(
    Vector3 vector __gc[],
    Matrix sourceMatrix
) __gc[];
JScript .NET public static function TransformNormal(
    vector : Vector3[],
    sourceMatrix : Matrix
) : Vector3[];

Parameters

vector Microsoft.DirectX.Vector3[]. Array of source Vector3 structures.
sourceMatrix Microsoft.DirectX.Matrix. Source Matrix structure.

Return Value

Microsoft.DirectX.Vector3[]. Array of Vector3 structures that contain 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.
