00:00:00.06 --> 00:00:01.08

- [Instructor] All right,

now what we've come up with



2

00:00:01.08 --> 00:00:03.07

so far I think looks really cool,



3

00:00:03.07 --> 00:00:06.00

but it's pretty darn simple to pull off,



4

00:00:06.00 --> 00:00:08.04

because after all, we're

just asking Illustrator



5

00:00:08.04 --> 00:00:11.08

to take a circle and repeat

it all over the place,



6

00:00:11.08 --> 00:00:14.09

and we're making the program

do all of the work for us.



7

00:00:14.09 --> 00:00:15.09

What if you want to create



8

00:00:15.09 --> 00:00:20.01

a conceptually more complex

effect like this one right here,



9

00:00:20.01 --> 00:00:23.05

and I should say that I was

inspired to create this artwork



10

00:00:23.05 --> 00:00:27.01

by a file that I found,

and here's the ID number,



11

00:00:27.01 --> 00:00:29.07

from the Dreamstime image library,



12

00:00:29.07 --> 00:00:32.04

about which you can learn

more and get some great deals



13

00:00:32.04 --> 00:00:36.04

at dreamstime.com/deke.php,



14

00:00:36.04 --> 00:00:39.00

but I will say that I

recreated the artwork,



15

00:00:39.00 --> 00:00:40.05

so I drew this from scratch,



16

00:00:40.05 --> 00:00:44.01

just as you'll be drawing it

from scratch along with me,



17

00:00:44.01 --> 00:00:46.01

and it is a design that's been out there



18

00:00:46.01 --> 00:00:47.07

for a very long time.



19

00:00:47.07 --> 00:00:49.01

Now what you have to appreciate



20

00:00:49.01 --> 00:00:51.03

when you're creating a pattern like this,



21

00:00:51.03 --> 00:00:53.09

especially an absolutely seamless one,



22

00:00:53.09 --> 00:00:57.01

which is what we have here,

is that everything has to fit



23

00:00:57.01 --> 00:01:02.09

inside a rectangular tile that

repeats over and over again.



24

00:01:02.09 --> 00:01:04.07

Now you might say to

me, "Wait a sec, Deke.



25

00:01:04.07 --> 00:01:06.05

"You just showed us a few movies ago,



26

00:01:06.05 --> 00:01:10.01

"how you can create hexagonal

tiles," and it's true.



27

00:01:10.01 --> 00:01:13.07

Bricks and hexagons are things

that Illustrator does for you



28

00:01:13.07 --> 00:01:16.06

but in the background,

everything gets boiled down



29

00:01:16.06 --> 00:01:20.04

to a rectangle that is

repeated in an absolute grid,



30

00:01:20.04 --> 00:01:21.09

and to demonstrate what I mean,



31

00:01:21.09 --> 00:01:24.06

I'll go ahead and switch

over to this guy right here.



32

00:01:24.06 --> 00:01:28.09

This is in fact a rectangular

tile that Illustrator uses



33

00:01:28.09 --> 00:01:30.06

to create this effect here,



34

00:01:30.06 --> 00:01:32.03

and to demonstrate that that's the case,



35

00:01:32.03 --> 00:01:35.01

I'll go ahead and repeat

this tile manually.



36

00:01:35.01 --> 00:01:36.08

So I'm zoom out here a little bit,



37

00:01:36.08 --> 00:01:38.06

and then I'll grab this guy,



38

00:01:38.06 --> 00:01:40.06

and I'll drag by the bottom-right corner



39

00:01:40.06 --> 00:01:42.08

until it snaps into alignment up there



40

00:01:42.08 --> 00:01:45.05

and then I'll press the alt key

or the option key on the Mac



41

00:01:45.05 --> 00:01:47.00

in order to duplicate it,



42

00:01:47.00 --> 00:01:50.07

and now I'll drag this

top-right point down like so



43

00:01:50.07 --> 00:01:53.06

until it snaps into alignment,

and I'll press the alt key



44

00:01:53.06 --> 00:01:55.06

or the option key on the Mac once again.



45

00:01:55.06 --> 00:01:57.07

Then I'll just go ahead

and grab all these guys



46

00:01:57.07 --> 00:02:00.05

with my black arrow tool,

and I'll drag this point



47

00:02:00.05 --> 00:02:02.09

over to the right, and

I'll press the alt key



48

00:02:02.09 --> 00:02:05.01

or the option key on

the Mac to duplicate it,



49

00:02:05.01 --> 00:02:07.01

and then I'll just go

ahead and do the same



50

00:02:07.01 --> 00:02:10.02

with this bottom right point,

and I'll press the alt key



51

00:02:10.02 --> 00:02:12.07

or the option on the Mac to duplicate it,



52

00:02:12.07 --> 00:02:16.07

and you can see that indeed

we have the hexagonal tile.



53

00:02:16.07 --> 00:02:18.07

Notice that we've got

this guy in the center



54

00:02:18.07 --> 00:02:22.02

surrounded by six of his friends.



55

00:02:22.02 --> 00:02:24.05

And so even though it

looks like a hexagon,



56

00:02:24.05 --> 00:02:28.00

it's actually a rectangular pattern tile.



57

00:02:28.00 --> 00:02:31.01

All right, so if we're going to

figure out something like this,



58

00:02:31.01 --> 00:02:33.01

then at the very least,

what we need to know



59

00:02:33.01 --> 00:02:35.09

is the distance from the top of one crest



60

00:02:35.09 --> 00:02:39.04

to the top of the next

crest in the same wave,



61

00:02:39.04 --> 00:02:41.08

and that is going to

translate to the width



62

00:02:41.08 --> 00:02:44.04

of our rectangular tile.



63

00:02:44.04 --> 00:02:48.06

So what we need to do is a

little bit of planning upfront,



64

00:02:48.06 --> 00:02:52.04

which is why I came up with

the wave diagram right here.



65

00:02:52.04 --> 00:02:55.06

Now I'm the first to admit

that I actually just plowed



66

00:02:55.06 --> 00:02:58.02

my way through this

project and figured it out



67

00:02:58.02 --> 00:03:01.01

through trial and error,

but I could have made things



68

00:03:01.01 --> 00:03:03.05

work a lot more quickly,

if I could have come up



69

00:03:03.05 --> 00:03:06.07

with some numbers upfront,

and if you know these numbers,



70

00:03:06.07 --> 00:03:09.07

then my approach is going

to make a lot more sense.



71

00:03:09.07 --> 00:03:11.09

So I eventually figured

out that the distance



72

00:03:11.09 --> 00:03:15.02

from the top of one crest

to the top of the next crest



73

00:03:15.02 --> 00:03:19.06

on that same wave is 300 points,

and it could be any number,



74

00:03:19.06 --> 00:03:22.00

but 300 points works out very nicely,



75

00:03:22.00 --> 00:03:24.08

which means that the distance

from the top of one crest



76

00:03:24.08 --> 00:03:28.02

to the valley of the next

is half that distance



77

00:03:28.02 --> 00:03:30.02

or 150 points.



78

00:03:30.02 --> 00:03:32.09

Now notice that each one of these waves



79

00:03:32.09 --> 00:03:35.06

is a kind of calligraphic brushstroke.



80

00:03:35.06 --> 00:03:37.06

So we start thick, we get thinner,



81

00:03:37.06 --> 00:03:39.06

and then we thicken up even more.



82

00:03:39.06 --> 00:03:42.09

So at the apex, where

the stroke is thickest,



83

00:03:42.09 --> 00:03:46.04

I decided I wanted it

to be about 10 points,



84

00:03:46.04 --> 00:03:49.01

and that translates to

seven points to the right,



85

00:03:49.01 --> 00:03:51.02

and seven points down.



86

00:03:51.02 --> 00:03:54.06

Now you may wonder how 10

points, down and to the right,



87

00:03:54.06 --> 00:03:57.01

by the way, so we're moving

one side to the next,



88

00:03:57.01 --> 00:04:00.02

negative 45 degrees right

there, you may wonder how



89

00:04:00.02 --> 00:04:03.07

10 points translates to

seven right and seven down.



90

00:04:03.07 --> 00:04:07.00

Well, one way to figure that

out is Pythagorean theorem,



91

00:04:07.00 --> 00:04:09.03

which is some rudimentary algebra



92

00:04:09.03 --> 00:04:11.03

that you probably learned

back when you were



93

00:04:11.03 --> 00:04:13.07

in middle school, or at

the very least high school,



94

00:04:13.07 --> 00:04:16.05

but not everyone knows

that, and a lot of designers



95

00:04:16.05 --> 00:04:19.02

absolutely hate math, and so another way



96

00:04:19.02 --> 00:04:21.01

to figure this out is to make Illustrator



97

00:04:21.01 --> 00:04:22.07

do the work for you.



98

00:04:22.07 --> 00:04:25.09

Notice if I go ahead and

just draw a rectangle,



99

00:04:25.09 --> 00:04:27.08

and any old rectangle will do,



100

00:04:27.08 --> 00:04:29.08

so I'll just go ahead and

drop that guy right there,



101

00:04:29.08 --> 00:04:32.08

and then I switch back

to the black arrow tool.



102

00:04:32.08 --> 00:04:36.01

If I press the enter key to

bring up the Move dialog box,



103

00:04:36.01 --> 00:04:38.04

I don't want to move it this

far because that moves it



104

00:04:38.04 --> 00:04:41.09

right off screen, but let's

say I do want to move it



105

00:04:41.09 --> 00:04:45.05

a distance of 10 points,

and I want that angle to be



106

00:04:45.05 --> 00:04:49.00

negative 45 degrees because

negative 45 degrees,



107

00:04:49.00 --> 00:04:52.04

as you can see inside this

little widget, is down



108

00:04:52.04 --> 00:04:53.08

and to the right.



109

00:04:53.08 --> 00:04:56.02

Well then, Illustrator's

actually going to tell you



110

00:04:56.02 --> 00:04:59.06

that the distance to the right

needs to be approximately



111

00:04:59.06 --> 00:05:02.04

seven points and the

distance down needs to be



112

00:05:02.04 --> 00:05:05.01

approximately seven points as well,



113

00:05:05.01 --> 00:05:09.00

but just to make things

easier, I went with these guys



114

00:05:09.00 --> 00:05:11.06

being absolutely seven and seven



115

00:05:11.06 --> 00:05:16.00

and the distance value working

out to be approximately 10.



116

00:05:16.00 --> 00:05:19.00

Same with the distance

from the top of one wave



117

00:05:19.00 --> 00:05:20.09

to the top of the next.



118

00:05:20.09 --> 00:05:23.05

I wanted it to be absolutely

20 points to the right



119

00:05:23.05 --> 00:05:26.07

and 20 points down, and that

translates to approximately



120

00:05:26.07 --> 00:05:30.07

28 points, and to show you

that is absolutely the truth,



121

00:05:30.07 --> 00:05:33.07

I'll go ahead and enter

a horizontal value of 20



122

00:05:33.07 --> 00:05:36.04

and a vertical value

of 20, and you can see



123

00:05:36.04 --> 00:05:40.09

that our distance value is

now approximately 28 points



124

00:05:40.09 --> 00:05:44.03

at an angle of negative 45 degrees.



125

00:05:44.03 --> 00:05:46.01

All right, so I'll just

go ahead and cancel out



126

00:05:46.01 --> 00:05:49.05

and I'll delete that rectangle as well.



127

00:05:49.05 --> 00:05:51.09

All right, so with this

basic information in mind,



128

00:05:51.09 --> 00:05:54.09

we're going to start working

on this seamlessly elaborate



129

00:05:54.09 --> 00:05:58.01

and absolutely seamless pattern starting



130

00:05:58.01 --> 00:05:59.06

in the next movie.
