1
00:00:00,630 --> 00:00:00,900
All right.
1

2
00:00:00,930 --> 00:00:02,740
So that was pretty simple, right.
2

3
00:00:02,800 --> 00:00:04,100
And that's all thanks to ARKit.
3

4
00:00:04,230 --> 00:00:07,610
So let's use it to create something else. Instead of using a cube,
4

5
00:00:07,650 --> 00:00:13,800
let's create a sphere this time. So we'll call it sphere. And instead of using SCNBox, there's something
5

6
00:00:13,800 --> 00:00:16,210
called SCNSphere.
6

7
00:00:16,410 --> 00:00:23,260
And all we have to do is give it a radius and let's say maybe 20 centimeters in radius.
7

8
00:00:23,280 --> 00:00:25,730
So that's about 40 centimeters in diameter.
8

9
00:00:25,740 --> 00:00:31,920
I think my room can handle that. And instead of adding the material to the cube, we'll add it to the sphere
9

10
00:00:31,950 --> 00:00:38,530
this time. And also change the geometry that's associated with the node to our new sphere.
10

11
00:00:38,760 --> 00:00:44,880
But this time, I want to make it a little bit fancier. Instead of just having the UIColor red which is
11

12
00:00:44,880 --> 00:00:46,750
nice enough if we're making a dice,
12

13
00:00:47,070 --> 00:00:48,210
but let's go crazy,
13

14
00:00:48,240 --> 00:00:50,950
let's put the moon into our living room.
14

15
00:00:51,150 --> 00:00:54,120
So even though it sounds pretty crazy, it's actually really easy to do.
15

16
00:00:54,300 --> 00:00:59,430
All we need is just a Texture map. And there's a website called solarsystemscope.com.
16

17
00:00:59,550 --> 00:01:06,690
And if you go into Textures, you'll see that they have loads of high-resolution images of a whole bunch
17

18
00:01:06,690 --> 00:01:14,380
of planets, Earth, or sun, moon, stars, Milky Way, and fictional. And you can download them for free.
18

19
00:01:14,400 --> 00:01:22,020
So in our case, we wanted the moon. And why go for high resolution, if you can go for extreme resolution?
19

20
00:01:22,020 --> 00:01:26,440
Well, obviously, if you're deploying the app into the App Store, you might want to make some considerations.
20

21
00:01:26,460 --> 00:01:31,490
But right now, I just want an extreme resolution moon in my living room.
21

22
00:01:31,680 --> 00:01:34,680
So I'm going to download this 8K file.
22

23
00:01:34,680 --> 00:01:34,890
All right.
23

24
00:01:34,920 --> 00:01:39,300
So once you've got it downloaded, you can actually see that this is just a flat map.
24

25
00:01:39,300 --> 00:01:42,240
It almost looks a bit like, you know, a world map
25

26
00:01:42,240 --> 00:01:47,770
if you had a picture of the earth. It's just the representation of a sphere laid down flat.
26

27
00:01:47,880 --> 00:01:53,970
And this is what we're going to use to essentially wrap around our sphere and make it look like as if
27

28
00:01:53,970 --> 00:01:56,580
we have a moon in our 3D space.
28

29
00:01:56,580 --> 00:01:58,840
So find that moon image that you downloaded.
29

30
00:01:58,860 --> 00:02:06,230
So I think it's called moon.jpg. And you're going to drag it into your art.scnassets folder.
30

31
00:02:06,270 --> 00:02:09,700
So just click and drag and there we go.
31

32
00:02:09,720 --> 00:02:10,700
It's incorporated.
32

33
00:02:11,430 --> 00:02:18,480
And then, instead of using UIColor, I'm going to show you how easy it is to add a Texture map to are
33

34
00:02:18,490 --> 00:02:19,530
3D object.
34

35
00:02:19,530 --> 00:02:25,740
So in this case, instead of having on diffuse property being a UIColor, I'm going to just use UIImage
35

36
00:02:26,130 --> 00:02:32,030
named. And remember that because it's resting inside the art.scnassets folder,
36

37
00:02:32,070 --> 00:02:34,730
it's actually not at the same hierarchy as our ViewController.
37

38
00:02:34,730 --> 00:02:39,780
So we're going to have to navigate into it, just like the way that they did here with the ship.
38

39
00:02:39,780 --> 00:02:45,600
So, in fact, I'm just going to copy that and paste that in. And instead of ship.scn, I'm going to
39

40
00:02:45,600 --> 00:02:48,090
change it to moon.jpg.
40

41
00:02:49,080 --> 00:02:56,400
So, now we are draping this moon.jpg Texture map onto our sphere, and we're going to place it at
41

42
00:02:56,400 --> 00:03:01,860
the same position as before with our box, and then we're going to make it appear on our sceneView.
42

43
00:03:02,040 --> 00:03:03,150
So let's give it a go.
43

44
00:03:21,150 --> 00:03:22,080
And there you have it,
44

45
00:03:22,080 --> 00:03:24,060
the moon in your living room.
45

46
00:03:24,210 --> 00:03:29,880
So I hope you enjoyed that, creating boxes, creating spheres, giving them Texture maps, giving them colors.
46

47
00:03:29,880 --> 00:03:36,000
Now in the next lesson, we're going to be getting on with our real task which is creating our 3D dice.
47

48
00:03:36,180 --> 00:03:41,460
And I'm going to show you how you can import other people's 3D models, so that you can easily use them in
48

49
00:03:41,460 --> 00:03:42,390
your project.
49

50
00:03:42,390 --> 00:03:43,110
So I'll see you there.
