Vocabulary:
Projection theory
Lines of sight (LOS) Parallel projection |
comprises the principles used to graphically represent 3D objects and structures on 2D media such as paper and the computer screen
are imaginary rays of light between an observer's eye and an object requires that the object be positioned at infinity and viewed from multiple points on an imaginary line parallel to the object. |
