Parameters
Float2
coordinate
The coordinate vector to transform. 
Matrix
transform
The transformation Matrix. 
Returns
Float2
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 w component to be one and therefore makes the vector homogeneous. The homogeneous vector is often preferred when working with coordinates as the w component can safely be ignored.

Performs a coordinate transformation using the given Matrix.
Declaration
public static void TransformCoordinate(ref Float2 coordinate, ref Matrix transform, out Float2 result)
Parameters
Float2
coordinate
The coordinate vector to transform. 
Matrix
transform
The transformation Matrix. 
Float2
result
When the method completes, contains the transformed coordinates. 
Remarks
A coordinate transform performs the transformation with the assumption that the w component is one.

public static Float2 TransformNormal(Float2 normal, Matrix transform)
Parameters
Float2
normal
The normal vector to transform.

Remarks
A normal transform performs the transformation with the assumption that the w component is zero. This causes the fourth row and fourth column 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 preferred for normal vectors as normals purely represent direction rather than location because normal vectors should not be translated.
