o make things easy to understand and then apply – we got a horizon line, which is set by default at the standard human line of sight.

If the standard person has 1.80 meters in all our drawings (and unlike snails,we humans do not have eyes on the top of our head), then the standard horizon line should be lower than the human height…. so that puts it at 1.65 meters.

Relating to the horizon line, all objects can fit into three categories:

They are below the horizon line – that makes them fit into a ‘top down view’ like you are literally looking down at them.

Some examples of objects like this? The computer or laptop you are seeing this lesson from… more than likely it is sitting on a desk somewhere so if you are standing up it is below your horizon line.

Other top down objects – the desk or table you are sitting on- tables usually are 70 cms tall or 120 if you are watching this at a bar somewhere…

So a table or bar surface fit in a top down box perspective as it is much lower than the standard horizon line.

2.) They are above the horizon line, so if objects are above the horizon line this means you can see the bottom face of each object and that perspective is a Bottom-Up Perspective.

If you are inside a building… look up at the ceiling. Would you agree that the ceiling is a really flat box which floats above your head, so is in a bottom-upperspective.”

Other than that maybe there is a ceiling lamp nearby… however,curvilinear the lamp, it as well fits into a bottom-up perspective.

3.)An object that is so large that it goes above and below your perspective line is in a Building View perspective.Just stop for a moment and look out the window at all buildings surrounding you… these all fit into the ‘building view’ type of perspective.

Obviously, it all depends on the composition of your image – you could have a small object but if you look really close at it might seem like it is drawn in building view perspective.
