The Basics of Local Light

And here are a couple I did up today. These again are all adapted from the book Creative Layout by Joko, Leandro Ng, Thomas Denmark, et al.

In this last example, you would need to use the left VP to make the left Elevation of Light, and the right VP to make the other. In other words, you'd be taking the height of the light source (the central vertical dotted line) and pushing it toward each respective VP. It would automatically shorten a bit by being moved farther away in both cases. (That is not the case in this drawing, because it is isometric, like our recent in-class shadow plotting exercise, and lives in a world without VPs.)

Note that the shadow of the leftmost red stick (or baton rouge in French) obeys the Law of Parallels when it falls on the floor.
