TransformCoordinate(Vector3, Matrix)

Performs a coordinate transformation using the given Matrix.

public static Vector3 TransformCoordinate(Vector3 coordinate, Matrix transform)

Parameters

coordinate Vector3: The coordinate vector to transform.
transform Matrix: The transformation Matrix.

Returns

Vector3: The transformed coordinates.

Remarks

A coordinate transform performs the transformation with the assumption that the w component is one. The four dimensional vector obtained from the transformation operation has each component in the vector divided by the w component. This forces the wcomponent to be one and therefore makes the vector homogeneous. The homogeneous vector is often prefered when working with coordinates as the w component can safely be ignored.

TransformCoordinate(ref readonly Vector3, ref readonly Matrix, out Vector3)

Performs a coordinate transformation using the given Matrix.

public static void TransformCoordinate(ref readonly Vector3 coordinate, ref readonly Matrix transform, out Vector3 result)

Parameters

coordinate Vector3: The coordinate vector to transform.
transform Matrix: The transformation Matrix.
result Vector3: When the method completes, contains the transformed coordinates.

Remarks

TransformCoordinate(Vector3[], ref readonly Matrix, Vector3[])

public static void TransformCoordinate(Vector3[] source, ref readonly Matrix transform, Vector3[] destination)

Parameters

source Vector3[]: The array of coordinate vectors to trasnform.
transform Matrix: The transformation Matrix.
destination Vector3[]: The array for which the transformed vectors are stored. This array may be the same array as source.

Remarks

Exceptions

ArgumentNullException: Thrown when source or destination is null.
ArgumentOutOfRangeException: Thrown when destination is shorter in length than source.

TransformNormal(Vector3, Matrix)

Performs a normal transformation using the given Matrix.

public static Vector3 TransformNormal(Vector3 normal, Matrix transform)

Parameters

normal Vector3: The normal vector to transform.
transform Matrix: The transformation Matrix.

Returns

Vector3: The transformed normal.

Remarks

A normal transform performs the transformation with the assumption that the w component is zero. This causes the fourth row and fourth collumn of the matrix to be unused. The end result is a vector that is not translated, but all other transformation properties apply. This is often prefered for normal vectors as normals purely represent direction rather than location because normal vectors should not be translated.

TransformNormal(ref readonly Vector3, ref readonly Matrix, out Vector3)

Performs a normal transformation using the given Matrix.

public static void TransformNormal(ref readonly Vector3 normal, ref readonly Matrix transform, out Vector3 result)

Parameters

Remarks

Remarks
