-Have some helpful descriptions to add to this class? Edit this page and add your insight ​to the Wiki!+A normalized vector is a vector whose length is equal to one, otherwise known as a unit vector. To convert a vector into a unit vector, get the normalization factor by calling the ''​Normalize''​ function, then divide each of the vector'​s x, y, z, and w coordinates by that factor.
