All language subtitles for 022 Drawing 3D Forms In Characters.en

In this lecture we're going to be talking about how to draw three forms but more importantly how to

understand three forms.

So it's really important that we understand 30 forms when we're drawing our characters and the way we

can do this is by using what's called wire frames and construction lines.

Now we've already kind of gone over construction lines and this just helps us understand the surface

of our form basically.

And this is really important when you're drawing your characters because you need to understand what

the three dimensional aspects of the different parts of your character are.

So that way you can rotate them in your head.

You can move them into different positions.

So in this lecture we're gonna be talking about wire frames and construction lines.

So let's go ahead and let's draw a cube somewhere go ahead.

Just draw a nice big cube like this.

I want to show two of the surfaces so we get some nice perspective in there.

All right great.

So now that we have a cube we can kind of understand just inherently what the surface of this Cuba is

but just to make sure what we can do is we can go ahead and we can add a wireframe to this.

So wireframe is basically just a grid system sort of.

In this case is a grid system sometimes it won't even be a grid system it'll just be lines.

But in this case we're gonna make it a grid system so we're just going to draw straight lines on the

surface here.

We'll do the same thing on the top of the line all my lines up

and so as far as we can tell this grid system these lines are making up a flat surface.

Now what if over here on this surface we want to go ahead and let's just draw on Ellipse on there.

This won't be a perfect circle in perspective but it'll be close enough to draw the ellipse LIKE THAT.

WHAT DO WE HAVE AN ELLIPSE on there.

So let's go ahead and let's just draw a grid system all the way crosses but where we get to the edge

of that ellipse.

Let's go ahead and not draw in there for now.

Now if we were to just go ahead and continue these lines through that ellipse it would basically just

tell us that that is a flat surface but we can give it more information and more dimensions or not dimension

but we can just change the surface and the form of our cube by changing the way our wire mesh goes.

So many go ahead and draw these lines going across here as well avoid the circle for now.

So what we can do is if we want to make this look like a round scooped out sort of concave sphere what

we can do is we can go ahead and take instead of having this line go straight across we can curve it

in like that.

Do the same thing with this one to the point where we can't even see it then we can do the same thing

with these.

So this will curve back.

It will actually get overlap.

You won't see it until it comes out right there to the same thing right there and do the same thing

right there.

And you can see that this tells us a lot more information about the surface because we have that wire

mesh in there.

So we know that that's not flat.

It's actually curved and concave inside of there.

We don't even have to add in any highlights or shadows or anything like that to give that information.

Now we don't ever really want to draw these wire meshes on our characters sometimes we want to do a

few construction lines here and there to help us understand the form.

But the point of the wire mesh is it so that we can practice and exercise our ability to see form when

we're drawing form and it's our ability to understand that form and its surface.

And so by practicing it on different forms with this wire mesh it allows us to do that but I just want

to specify that most time you're not going to want to be drawing that.

So let's go ahead and have a look at another example.

Let's go ahead and do a sphere.

So I want to draw circle like this.

What I want to do is I'm going to pick a point I want to pick a point down here and have a line going

through that and just draw kind of a cone at the end of it and we'll be coming out this other side.

We won't see where draw a cone on that side as well.

So let's go ahead and let's try to understand the surface of this form.

So we want to go ahead and add lines to it that kind of represent a beach ball so we can start by drawing

a straight line coming across here.

But then as we get out just like a beach ball these lines start to curve outwards like that.

But as it gets to this back edge it's going to curve back around and wherever that this pole six through

the backside of that ball that's where those are curving back around.

So we don't want to actually see where they curve around to in the end so we can go ahead and just keep

drawing these all the way around

and start on this side as well

perfect.

So now we have a little bit more understanding of the surface of that sphere.

Now this isn't necessarily perfect.

Surface a grating but it's close enough.

And like I said we just want to get things close enough.

They don't have to be perfect when you're drawing characters.

We don't have to go in there and draw perfect prospective lines of stuff like that to make sure that

our forms and perspective was perfect.

Then let's go ahead and let's add some rings around here so starting from this point I'm to go ahead

and add a ring like that.

So it's just kind of an ellipse now we go ahead and add another one right here around it.

But bigger and as you can see it stays closer to this edge and it's touching the edge until we get out

here.

And then part of it is actually almost missing that we get out here and it just becomes kind of a curved

line.

We get out here and other curved line

just like that.

So there we go.

Now we got a little bit more information about the surface of our sphere and this is just again to help

us understand the surface of a sphere.

But we don't necessarily have to draw this every time we draw a sphere.

It's just so that our brain can really start wrapping around these forms.

All right.

So let's go ahead and let's draw another sphere and let's try some construction lines

all right.

So there we go there's our circle for the base for a sphere and let's say that we want let's draw three

circles within this fear that will help us understand the sphere itself.

So going to draw one ellipse like that and it's just touching from top to bottom

and then going to do another one out here that'll be smaller.

And we just want each one to be touching the top and the bottom like that.

And I'm just drawing these kind of quickly.

You don't want to go slow when you draw these.

Otherwise you're not going to turn out very round.

All right.

Great.

And then let's go ahead and do the same thing but from this side.

So we know that we're kind of seeing this from angled from the side because we can actually see these.

You could almost think of them as disks.

Those are desks and we're seeing them in perspective inside of our sphere.

So this is a clear sphere that we can go ahead and draw this right here like that.

So it's touching from that edge to that edge.

So it's just the same.

And we'll do the ones down here as well.

All right.

Great.

Now to get a little bit better understanding about this we can go ahead and draw a line where these

two disk cross so I can go and draw a line right there and I'm just drawing from that point to that

point where this circle touches that edge and where the bottom of the circle touches that edge.

I can do the same to both of these and these are corners where they touch so we don't have to really

do anything about those.

I can do the same thing up here just like that.

And that also doing this exercise gives us a little bit more understanding about what the sphere is

and how things can fit inside of it.

So let's go ahead and let's label these.

So that's a wireframe

This is a wireframe.

And these I would consider more of construction lines.

All right.

Let's go ahead and move on and look at a few more things.

And if you wanted to do this a little bit more simple what you could do is you could just draw a sphere

here

and just two two crossing desks so you could do a disk like that and a disk like this

right.

Draw a line right there to show where that's crossing through each other.

And that's just a simpler version of that right there anyways.

So let's go ahead and let's move on.

So how else can we use construction lines.

Well let's say that we are drawing a cone.

So we go ahead and just draw lips like that and then we're gonna go ahead and draw a point going up

to about the center

where we can use construction lines to help us understand this form so we can go ahead and just copy

this curve basically and draw it around like that

that just helps us understand this form a little bit more

and as you can see in this case I just did the outside surface line.

So kind of like with the sphere here with this wireframe there I kind of did just a wireframe around

this.

I didn't really draw the actual discs in there that go all the way around.

Is this as if this was a see through comb so you can do it either way.

You can draw it like this we can see through it or you can draw it like this or you just draw the surface

lines that wrap around it but you can't see through it.

OK.

Let's do a sphere.

So go ahead drawn over like that dark net and a little bit.

Then I'll draw a line coming off like this light coming off like that.

Copy that curve over to the backside.

Now we can go ahead and add some wireframe into this just by adding some lines that wrap around it in

the same curve

so really these could be thought of as wire frames or they can be thought of as construction lines they

kind of are interchangeable and it's not really that important what you call them.

It's just the whole concept of all of this is understanding the surface and understanding it in your

mind.

So once we do these exercises it'll help us when we're drawing our character so if we draw a forearm

for example and it's a cylinder we're gonna understand how that curves around because in our mind we

can see that grid system around that or those or lines construction lines that wrap around the surface

of that.

So this is all nice and dandy.

Understand how to do this on just simple shapes like that.

But what if we're doing more organic shapes so let's say let's do a simple cloud shape for example.

I'm gonna go ahead and just kind of sketch out some ovals like that and this is gonna be basically circles

and perspective just being squashed because the angle we're looking at him from and then I'm going to

go ahead and just draw kind of a round shape coming off each one

just like that and then I can go ahead and outline that

like that.

So now we kind of have the form of a sort of cartoonish looking cloud but we can go ahead and use this

form and try to understand it better by drawing construction lines.

So I go ahead and start by making this bottom surface flat and I can do that by just drawing straight

lines coming across the

like back now that looks like a flat surface.

Now we could also go ahead and shave that and a little bit.

But you don't have to.

But I just think it helps kind of differentiate between the two surfaces that we can go ahead just start

drawing curved lines around these round sort of spherical surfaces

like that and now we have some wire framing going around our cloud and it really is helping us understand

what kind of surface this cloud has.

So it's around on top and flat on the bottom.

All right let's go ahead and look at another example so let's say we do some kind of like almost like

a carrot shape.

So it's kind of a rounded triangle shape like that.

That'll be the base of our form I guess it looks kind of like candy corn actually.

So now we can just go ahead and add some rings that kind of wrap around this so I can wrap it around

like this one right there right there right there.

Maybe we could even add a little bit more of those in just have more understanding right.

So by adding those lines then we just get a better understanding of what that surfaces.

Let's say that we were doing some mountains or something like that some cartoonish mountain so we're

not going to be super detailed ones but just to get the point across.

You're gonna be very similar to the clouds basically.

Just draw something like that

then we can go ahead and just draw some bands that come across these rounded surfaces that will draw

those all the way across from

like that by drawing those lines.

You just get a little bit better idea of what that surfaces like.

Now one sort of example that's gonna be really important to understand is where surfaces change from

one surface or angle or roundness or whatever it is it changes from area to area.

So an example of this would be let's say for example my full arm when we're drawing character for arm

sometimes we want to do something like this.

So I want to start by drawing on it lips like that because we're gonna be drawing sort of a cylinder

shape.

So it's gonna taper off like this.

So it kind of looks like it's gonna be a tapered cylinder but what we're going to do is at the other

side it's actually gonna morph into the rest area.

So we get a round area here and then it morphs into more of a square sort of shape down here at the

bottom so we can go head draw that square shape in at the other end just like that.

So what does that look like the transition from that form on that side to this form on this side.

Let's go ahead.

Let's kind of draw a corner piece coming off like that that kind of fades out towards the middle.

So we're gonna start off around here with our wireframe

and as we start to hit that line right there that's where things are gonna change.

So we're gonna start getting still these round lines but they're gonna start to angle right there and

pivot at that corner because those round ones for a few and then they're going to start going straight

like that

so that's more of a complex form that we would want to understand how it's work and how it's going from

a round smooth shape to a more angular square shape.

All right.

So basically these are all wire frames and some of them could be considered construction lines but generally

construction lines you're going to draw and your drawings and you're under drawn at least.

So for example on a character's head when we draw the sphere of the head we draw the center line of

the head and the eyeline.

Those are construction lines and those wrap around the form.

And so those are considered construction lines wire frames would be lines like this that you would never

actually draw when you're doing your drawings.

They're more as an exercise so you can start training your brain to actually see the surface of the

form in your head.

All right.

That brings us to the end of this lecture.

So I want you to make sure that you're drawing along with me.

And once you've finished this page that you just that I just drew I wanted to go ahead and posted to

the Q and A section of the course so we can all see the work you're doing now if you have any questions

make sure you also post those to the Q and A section of the course and I will see you guys in the next

lecture.
