 +**Perspective Projection** of a point in three dimensional space onto a two dimensional plane is achieved by drawing a line from a station point to the point in the three dimensional space and finding where the line intersects with the picture plane.
 +This needs to be done once for the top view and once for the side view.
 +Having found the intersection with the picture plane in both views, parallels can then be extended from those intersections.
 +The projection of the three dimensional point is found where those parallels intersect.
