Background on Perspective
Linear perspective is "linear" because we make objects conform to lines we construct that rise out of different vanishing points. The vanishing point is where the lines of perspective converge. That is, it's a point so far away objects disappear - they vanish. The lines all come together.
This works great when you're working with larger objects, rectangular or square objects and sizable distances. And works especially well when all your objects are buildings or cubes or fit neatly within the prescribed lines.
In this illustration you can see the basic elements of perspective: vanishing points, the horizon and lines of perspective.
The horizon line represents the surface of the earth. If it isn't explicitly drawn or painted, it's usually suggested or implied if not by the picture, then by your own brain.
Perspective is a fascinating study. There are several excellent source books mentioned in the library (that you can order directly - right now if you wish) through the Bookstore. If you want to do technical drawings freehand, it's a powerful skill to have at your fingertips. However, you don't need to get mired down in it to draw great caricatures!
