Drawing Tutorial – Part One – “Little house on the grid”


Ok, perspective…don´t cringe now.
It goes like this. No matter where you look at in nature or all around you you can always pull some imaginary straight lines from inside a central point of a feature you´re looking at.
And the only way to pull dozens of imaginary lines in your direction that don´t overlap each other is to give them diferent angles.

The degree of each angle does not matter now but it´s useful that you make sure you imagine the lines on your left to have the same inclination as the ones you pull on the right, just so that you can have a nice grid and not make a mess right at the foundation of what you´re going to use to grow a scenery out of it.
As you have to make sure these lines do not overlap naturaly as you spread them from a single point to the side they create that sense of 3D space because they endup occupying all the ground area of your pic.

So far so good, right ? You´ve created a little house on the horizon, you´ve pulled those imaginary lines on the ground and all the 3D effect is looking good.
But what happens if you want to add another house on the side ? Do you use the same lines you pulled from the central little house ?
And why did you pull those lines in the first place ?!
Well, more on this ahead, but for now you just place another house on the side right on top of the horizon and pull more lines from it.

You start by pulling a straight line right from underneath as you did on the original house, and then keep pulling lines to its sides.
This creates another grid that overlaps the original one. Don´t worry, this is what you want, only you don´t just know it yet.
Notice those original horizontal lines parallel to the horizon wich make the original green grid ? The closer to you, the bigger the spaces between them and as you have those you don´t need to create more to represent the floor.

Those central points on each feature from where you are pulling those imaginary lines, are what´s usualy called “vanishing points” and they´re one of the most important things you need to focus on when you´re creating a landscape, perhaps to illustrate a childrenbook or rendering a simple view.
A complex scenery can end up having dozens of individual vanishing points as each feature you want to put on the scenery needs those points (and their guide-lines) to be correctely placed on a 3D ground while relating well to the other scenery elements you have.
Are you cringing now ? It´s not that dificult. 😉

Look at my little house there. This is the most simple way to have a landscape. Ok, it´s not that impressive, but even with only the house and the guide lines, you already have a 3D space that people will imediatly recognize.

And all this without even adding anything else to the scenery. Anyone looks at this and imagines a house, the ground area and sky.

Then again, raise the horizon level and you get plenty more of ground area to fill in later.

The angle of the pulled imaginary lines from the vanishing point also determines the angle in wich the viewer is seeing your scenery.
If i had placed those pulled lines in a more tigh angle to the central one right from underneath the house the floor would look much more inclined that it is now.

If you don´t get what i´m saying, try to pull some lines with diferent inclination to see the illusion effect you get.

In this case i´ve spread those lines in a more wide angle across the canvas and so my ground area became less inclinated than the one from the other example above independently of the fact that this is the version with the horizon placed up.

The angle in wich you pull the imaginary lines from each vanishing point determines the illusion of looking down in a balanced way or creates the effect of a really high straightforward drop.

Experiment with pulling those lines from an object and try to create all sorts of grids yourselves to get a more realistic idea of what i´m trying to explain here. 😉

And of course this is the version with lots of sky area to fill in.
How do you fill in that area in a realistic way ?
Oh, yes, once again…perspective and vanishing points and some new imaginary grids to place things in. Mostly clouds.

More on this later, at the right time.
