| + | **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. | ||
