normal

Sometimes referred to as the surface normal or 'surface norm'; the normal is an axis that forms right angles with a surface that light is incident upon or with other lines. The normal is used to determine incident, reflective and refractive angles, as all of these angles are sketched and measured with respect to the normal of any given surface.
