- [Narrator] In this movie I'll introduce you
to the three kinds of 3D that are available to you
inside Illustrator.
Specifically rotate, extrude and bevel, and revolve.
And so let's start off by selecting these notes right here.
And then I'll go up to the effect menu, choose 3D,
and choose the simplest of the functions,
which is rotate.
Now notice when you first enter one of these dialogue boxes,
the preview check box is going to be turned off.
And that's just to save some processing time.
But you're going to need to turn that check box on
to see what you're doing.
Now you can rotate this 2D object in 3D space
by dragging one of the edges of this cube.
And notice as I drag this bottom edge, for example,
I'm tilting the notes backward.
Now I want you to notice a couple of things here.
First, this is a dynamic effect.
So we're not actually modifying the original path outlines,
we're just changing an image of that path on-the-fly.
Secondly, we're seeing what's known
as an axonometric projection.
Which is to say any parallel lines in the notes,
whether it's these bars up here
at the top of the sixteenth notes,
or these vertical stems.
They're all going to remain parallel.
And so, in other words, we have no perspective.
However, you can add perspective
using this perspective option right here.
And to do so, all you need to do
is click on that right-pointing arrow head
and then just drag this ball
in order to add some perspective to the effect.
And so as you can now see,
the parallel lines are no longer drawn
in a parallel fashion.
And as a result, the notes appear to be heading toward us.
Now I could bring the notes up
over on the left-hand side
so that we can see them all clearly
inside the document window
by dragging the left-hand edge of this cube.
And then, assuming I like what I see,
I'll just go ahead and click okay
in order to accept that change.
I want you to notice something else.
Let me see if I can bring it back.
You may find that every once in a while
you see outlines around the effect.
In which case, just go ahead and click okay
and those outlines will disappear.
Now while this rotate effect is interesting,
it's not really a true 3D effect
because we're not seeing any depth.
If you want to add some depth,
then you want to choose the extrude and bevel command instead.
And so I'm going to switch over to the appearance panel
and I'll turn off 3D rotate.
And so notice that it is a dynamic effect,
meaning that if you ever wanted to change it,
you would just click on the words 3D rotate
here inside the appearance panel.
But I want to apply a different kind of 3D
by going up to the effect menu, once again choosing 3D,
and this time choosing extrude and bevel.
Now if you're working along with me
and Illustrator asks you if you want to apply a new effect,
go ahead and click on that button
in order to bring up the 3D extrude and bevel options.
And notice, once again, we've got that cube.
And so I could drag that bottom edge up.
If I want to see what I'm doing, however,
I need to turn on the preview check box.
At which point, notice,
in addition to the fact that I am
rotating my notes in 3D space,
I'm also seeing these beveled edges.
And so, in other words, we have depth.
Alright, I'm going to go ahead and
drag this edge upward a little bit.
Once again, we're seeing that axonometric projection,
meaning that all the parallel lines remain parallel.
If you want to change that,
then you can increase the perspective value like so.
And again, if you end up with these wire frame edges,
all you have to do is click okay
in order to watch them disappear.
Alright, now let's check out the final effect,
which is known as 3D revolve.
I'm going to go ahead and switch back to the layers panel here
and turn off the 3D extrude layer.
And then turn on 3D revolve which, as you can see,
is a bunch of shapes carved into a half-circle.
Now the idea behind 3D revolve is that you are revolving
the paths around the common axis.
And as a result, we'll be able to take this half-circle
and turn it into a sphere.
So I'll go ahead and click on any one of these paths
to select all of them because
I've gone ahead and grouped them together in advance.
And now, go up to the effect menu.
Choose 3D and choose revolve.
And then, I'll go ahead and turn on the preview check box
so we can see all of those paths
revolved around the vertical axis
in order to convert what was formerly a kind of half-circle
into a sphere.
And again, if you want to rotate that object around,
then you can drag on the cube.
At which point you're going to see, in our case,
this wire frame globe.
Alright, so I'll go ahead and drag it down
to here, let's say.
You can add some perspective, if you like.
Although it may not ultimately be as compelling
as what we saw with extrude and bevel.
But certainly, we are adding perspective to the effect.
At which point I'll go ahead and click okay
to accept that change.
Alright, now because this is a dynamic effect,
I can modify the shapes to my heart's content
and the effect will update on-the-fly.
So for example, I'm going to press the A key
to switch to the white arrow tool.
Then I'll click off the shapes to deselect them.
And I'll try to find one of the dark shapes,
such as this guy right there.
And then I'll go up here
to the right-side of the control panel
and click on the select similar objects icon
to select all of the dark stripes.
And I'll go ahead and change them
to this shade of green, let's say.
And then I'll click on one of the white stripes.
It's a little bit hard to find.
But this guy right here is a representative.
And then I'll go ahead and click
on this select similar objects icon once again.
And this time I will select a light shade of green.
And just like that, without any waiting whatsoever,
Illustrator goes ahead and updates the 3D object.
And then if I want to change the angle of the sphere,
I press the V key to switch back to
my black arrow tool.
I click on any one of these shapes
in order to select the entire group.
I switch back over to the appearance panel
and click on the words 3D revolve.
Now this is going to be a little confusing,
the fact that Illustrator immediately turns off
that preview, once again.
So you'll need to turn it on in order to
see the shape that we had a moment ago.
And then you can go ahead and drag this cube
in order to rotate the sphere to any angle you like.
And I might go ahead and drag it around as well
and move this bottom edge upward just a little bit.
And then, assuming I like what I see,
I go ahead and click okay in order to accept that change.
And so those are your three varieties of 3D
inside Illustrator.
You have rotate,
which allows you to rotate a 2D object in 3D space.
You have extrude and bevel,
which allows you to add depth.
And then you've got revolve,
which allows you to revolve an object around a common axis
in order to create a volume metric
and nicely-lit form.
