Microsoft DirectX 9.0 SDK Update (October 2004)

Vector3.TransformNormal Method

Language:

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

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

Overload List

public void TransformNormal(Matrix);
public static Vector3 TransformNormal(Vector3, Matrix);
public static Vector3[] TransformNormal(Vector3[], Matrix);

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.
