Orthogonalize(Vector4[], Vector4[])

Orthogonalizes a list of vectors.

public static void Orthogonalize(Vector4[] destination, params Vector4[] source)

Parameters

Type	Name	Description
Vector4[]	destination	The list of orthogonalized vectors.
Vector4[]	source	The list of vectors to orthogonalize.

Remarks

Orthogonalization is the process of making all vectors orthogonal to each other. This means that any given vector in the list 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.

Exceptions

Type	Condition
System.ArgumentNullException	Thrown when `source` or `destination` is `null`.
System.ArgumentOutOfRangeException	Thrown when `destination` is shorter in length than `source`.

Parameters

Type	Name	Description

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.

Exceptions

Type	Condition
System.ArgumentNullException	Thrown when `source` or `destination` is `null`.
System.ArgumentOutOfRangeException	Thrown when `destination` is shorter in length than `source`.
