rays density is a positive integer.
object X and object Y are expressed in "mm" if the object is at a finite distance or in "degrees" otherwise.
norm. X on pupil and norm. Y on pupil are normalized parameters and therefore their value is in the interval [-1 , +1].
Dir. cosine X and Dir. cosine Y are cosines and therefore their value is also in the interval [-1 , +1].
rotation X, rotation Y and rotation Z are angles expressed in "degrees" and their value is in the interval [-90° and +90°].
