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(Double3[], ref Matrix, Double3[])
Performs a coordinate transformation on an array of vectors using the given Matrix.
public static void TransformCoordinate(Double3[] source, ref Matrix transform, Double3[] destination)
Parameters
source
Double3[]The array of coordinate vectors to trasnform.
transform
MatrixThe transformation Matrix.
destination
Double3[]The array for which the transformed vectors are stored. This array may be the same array as
source
.

TransformNormal(Double3, Matrix)
Performs a normal transformation using the given Matrix.
public static Double3 TransformNormal(Double3 normal, Matrix transform)
Parameters
Returns
- Double3
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 Double3, ref Matrix, out Double3)
Performs a normal transformation using the given Matrix.
public static void TransformNormal(ref Double3 normal, ref Matrix transform, out Double3 result)
Parameters
normal
Double3The normal vector to transform.
transform
MatrixThe transformation Matrix.
result
Double3When the method completes, contains 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.
