Now, first thing's first, we're going to need a newspaper to project AR content onto. 1
Now, if you have a copy of newspaper that's lying around, 2
then, of course, you can use that. But you will need to find a main image in the newspaper and you need 3
to be able to source the actual image online somewhere, and you'll also need to find a video that's relevant 4
to that content to make it work. 5
So it might be a little bit roundabout. 6
So for those of you guys who are following along with the tutorials, I've included a link in the course 7
resources list that downloads a copy of the front page of the Daily Prophet, 8
so the Harry Potter newspaper, and we're going to be working with this in the tutorial and I'll show 9
you how to source all of the content and materials. 10
So I recommend that if you're working along with the tutorial, just to simply head over here and download 11
this newspaper, and then print it out. 12
So we're going to be holding this newspaper in one hand and the app and the other in order to launch 13
our newspaper into AR. Once you've gotten hold of this newspaper, 14
we need a saved copy of the actual image. 15
So go ahead and open it up in preview and expand the image to as large as possible on your screen, and 16
then hold down command + control + shift, and 4, and that opens up our screenshot tool which we're going to 17
use to take a screenshot of this main image. 18
Now, once we let go, a copy of that screenshot is saved on our clipboard. 19
And if you're inside the preview application, if you hold down control + N, then it will create a new 20
file from that screenshot which we can now save, 21
and I'm going to call it just harrypotter, and I'm going to save it in the PNG format. 22
So, now make sure you can locate that Harry Potter image and make sure you've already printed out your 23
newspaper image. 24
The next step is sourcing our video. 25
Now, ideally, you would have some video that's lying around that you own, 26
that's also in the MP4 format. 27
It's really important that you try to find a video that's in the MP4 format. 28
It works best from a lot of experimentation with ARKit and with SceneKit. 29
Now, if you can't find anything that's suitable, then the easiest thing is just to head on to YouTube and 30
try to find a Harry Potter clip, 31
and this should give you something that's relatively short, 32
sort of two or three minutes long. 33
And we're going to copy this YouTube URL and head over to a YouTube downloader. 34
Now, of course, if you're building your app for launch on the App Store, then you need to make sure that 35
you own all of the media and all of the content that you're going to put into your app. 36
But just for the purposes of learning and education, we're going to download this YouTube video in an 37
MP4 format. 38
So I'm going to select the MP4 360, 39
so make it a little bit smaller, 40
and then I'm going to download this video. 41
Now, once we've downloaded the video, it's important that you rename it to the exact same name that you 42
gave your main image. 43
So I called the other one Harry Potter, 44
so I'm going to call this one harrypotter as well. 45
And we now have an image that we've printed out which we're going to launch our ARKit on. 46
We have the image that needs to be recognized in the newspaper 47
and we've also got the video that needs to play in the place of the image 48
once the ARKit app recognizes it. 49
So we're now all ready with our resources to get started building our app. 50
Once you've done all of that, then head over to the next lesson and let's get started building our magical 51
newspaper app.
