Remarks

Orthonormalization is the process of making all vectors orthogonal to each other and making all vectors of unit length. This means that any given vector will be orthogonal to any other given vector in the list.

Because this method uses the modified Gram-Schmidt process, the resulting vectors tend to be numerically unstable. The numeric stability decreases according to the vectors position in the list so that the first vector is the most stable and the last vector is the least stable.

public static Vector2 TransformCoordinate(Vector2 coordinate, Matrix transform)

Parameters

coordinate Vector2

The coordinate vector to transform.

transform Matrix

The transformation Matrix.

Returns

Vector2

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 Vector2, ref readonly Matrix, out Vector2)

Performs a coordinate transformation using the given Matrix.

Parameters

coordinate Vector2

The coordinate vector to transform.

transform Matrix

The transformation Matrix.

result Vector2

When the method completes, contains 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.

transform Matrix

The transformation Matrix.

destination Vector2[]

The array for which the transformed vectors are stored. This array may be the same array as source.

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.

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.

Parameters

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(Vector2[], ref readonly Matrix, Vector2[])

Performs a normal transformation on an array of vectors using the given Matrix.

public static void TransformNormal(Vector2[] source, ref readonly Matrix transform, Vector2[] destination)

Parameters

source Vector2[]

The array of normal vectors to transform.

transform Matrix

The transformation Matrix.

destination Vector2[]

The array for which the transformed vectors are stored. This array may be the same array as source.

Exceptions

ArgumentNullException

Thrown when source or destination is null.

ArgumentOutOfRangeException

Thrown when destination is shorter in length than source.
