OK in this lecture we're going to be talking about form which is the next element of sketching.
So form is pretty similar to shape right shape is kind of just what this something looks like from a
two dimensional perspective looking at a silhouette.
OK but form goes three dimensionally and form is what we use to describe volumes came.
So form is can be broken down any image any 3-D mass can be broken down into a handful of basic shapes
or variations of them.
So the first one is the pyramid which is a variation of the triangle.
The sphere cube or box doesn't have to be a cube it can be a rectangle shape and a cylinder.
Now all three objects are composed of one of these three shapes.
OK you can have lots of different variations of these.
For example there are four sided pyramids or you could have a three sided pyramid you can have a cone
which is a mix between a cylinder and a pyramid.
OK.
There's a cone.
You can have in addition to that you can have have a cone with the top cut off.
But all of these can be broken down into one of these objects Raider's spheroid which are a three dimensional
elliptical right.
More of an egg shape boxes can also be like this like a pyramid with the top cut off but not quite going
all the way.
OK.
Everything is made up of these.
OK.
Now if you can think about the thing you want to draw on your head three dimensionally and break it
down into these basic nature for you dry it will look a lot more accurate to what you're imagining in
your head and also look a lot more realistic.
So let me give you an example.
This here is a quick sketch of a T-Rex I did.
Now I'm looking at this at first glance it might seem pretty complex and made up of a lot of difficult
shapes but if we break it down we can see that's actually pretty basic.
So here is what it looks like broken down into shapes.
OK.
Now most of these are pretty some pretty simple.
So we have let's see if we're on the right lair here we just have a big cylinder right.
Nothing too fancy.
This is a big spheroid type shape.
Write the faces just stay.
I mean the lower jaw is pretty much just a pyramid shape at the top cut off.
Same with the head it's more of like just a box shape.
Right.
We have arms those cylinders and spheres for the joints legs of the giant cylinder tail is broken up
cylinders.
Feet are just big boxes.
Right.
So once you break this down we can begin to see it's pretty easy and you can even see right if we bring
it as an overlay underneath it's lines up perfectly right.
And it doesn't look weird or anything and of course some of these you'll have to refine the shape and
cut out of the shapes and add more.
In order to get exactly what you're looking for but more or less everything is going to be made up of
the shapes.
So when you're drawing instead of just coming into your drawing and trying to on the first go you know
you're coming in here and you're trying to let's say you're trying to draw.
We use a T-Rex an example say trying to draw a T-Rex and sort of just coming in here and you know start
drawing out the eyes and you know he starts sketching the whole thing and you just go right into the
drawing and you're trying to draw this you're going to have a hard time making it accurate.
Right.
Unless you draw a lot of T-Rex's.
So instead what you should do is come in here and think about what shapes that are right.
We know the head is more of a box shape to start off with k we can draw the mouth find the center line
of things to help us line stuff up right and then pretty quickly we can start to work out the shapes
of everything where everything needs to go OK.
And then you can cut into the shapes for where you want to be eyeholes right.
So on and so forth OK.
And you just keep working it until you can kind of build up where you're looking for.
Now this is just to help you get an idea right you don't need to go super detail and make everything
perfectly accurate in these volumes.
This is just to help you place stuff and understand its volumes before you just start going in for the
final details because after we do this right I'd say we we do the bottom draw as well and then we were
ready to start drawing over the top of this.
Now we can instead of just having to guess and figure out where we are volume wise we know exactly where
to draw stuff in.
And we know exactly where it fits in space and make more sense to us right instead of just trying to
kind of guess around and hope that we get lucky with where things are placed.
This helps us understand exactly where it needs to be placed in space so it takes practice right.
And if you can learn to visualize something in your head in 3-D that's going to be an invaluable skill
to you as an artist and I recommend you try and do that every day is to think when you're trying to
draw an object.
Don't just draw.
But think of it first in your head as a 3-D form and see if you can try and rotate it in your mind.
Right.
So you can see that the bottom drives a little bit small and that's why you can go ahead and go back
to the forms and just rework it until it's perfect.
That's it for a lecture on form and I'll see you guys in the next lecture.
