What’s Inside ARKit by Tutorials?
ARKit is one of those interesting technologies that seems fairly easy to use on the surface, and it’s true; ARKit does a lot of the heavy lifting of the mechanics behind the scenes for augmented reality apps.
But when it comes to creating immersive apps that offer realistic, engaging experiences for the user, that’s where it gets tricky. Fortunately, ARKit by Tutorials is here to help you navigate through the ins and outs of creating really great-looking ARKit apps that users will truly enjoy.
Here’s what’s contained in ARKit by Tutorials:
- Hello ARKit!: With ARKit, it only takes a few lines of code to start creating AR apps. ARKit does most of the the heavy lifting for you, so you can focus on what’s important: creating an immersive and engaging AR experience. In this chapter, you’ll take a look at what ARKit can do for you.
- Creating Your First ARKit app: It’s time to create your first ARKit application using Xcode’s built-in ARKit application template. You’ll also learn how to modify your app to accommodate basic UI elements such as labels and buttons to provide user feedback and receive user input.
- Basic Session Management: In this chapter, you’ll learn what an AR session is and how to manage it; this includes starting, stopping, and resetting it. You’ll also learn how to handle session errors and tracking issues that may occur during a typical AR application’s lifecycle.
- Adding 3D Objects: In this chapter, you’ll learn how to import, convert, texture and load 3D objects. Then you’ll learn how to place those 3D objects into augmented space. You’ll start with a 3D model materials overview by seeing how to create a virtual Earth, and then you’ll dive into building the poker dice game.
- Detecting Surfaces: In this chapter, you’ll learn how to detect real-world surfaces and how to manage updates to those surfaces properly. You’ll also learn how to create a focus cursor that will place itself on top of the detected surfaces through ray casting.
- Adding Physics: Physics adds another level of realism by making objects bounce off tables and the floor, just like they would in real life. In this chapter, you’ll learn all about physics, how to configure physics, and how to apply them to your virtual objects. You’ll also learn how to reach into the augmented world and interact with your virtual objects. The rest of the chapter will focus on finishing up the rest of the game itself.
- Building a Portal: Now that you’ve gone through the basics of ARKit and how to integrate it into your apps, you’ll put this knowledge to work. In this section, you’ll implement a portal app using ARKit and SceneKit. Portal apps can be used for educational purposes, like a virtual tour the solar system from space, or for more leisurely activities, like enjoying a virtual beach vacation.
- Adding Objects to your Virtual World: In the previous chapter, you learned how to set up your iOS app to use ARKit sessions and detect horizontal planes. In this chapter, you’re going to build up your app and add 3D virtual content to the camera scene via SceneKit. By the end of this chapter, you’ll know how to handle session interruptions and place objects on a detected horizontal plane.
- Geometry, Textures & Lighting: You learned how to add 3D objects to your portal scene with SceneKit. Now it’s time to put that knowledge to use and build a portal. In this chapter, you will learn how to create walls, a ceiling and roof for your portal and adjust their position and rotation; make the inside of the portal look more realistic with different textures; and add lighting to your scene.
- Detecting Placeholders: There is no doubt that ARKit is a technology whose natural primary target is entertainment. But it’s no surprise that ARKit is versatile enough to be useful for business-oriented applications. In the next four chapters, you’ll learn how to use ARKit, SpriteKit, SceneKit, Core Location and beacons to build an interactive billboard that can be put in a shop window to tease people with ads and promotions.
- Beginning User Interaction: In the previous chapter, you learned how to detect a rectangle, how to take advantage of the Vision framework and how to turn a detected surface into an ARKit plane. However, you left the plane generation chapter with one outstanding issue: it’s not oriented correctly. You’ll fix that in this chapter. You’ll also “upgrade” the rectangle detection with QR code detection and you’ll add some user interaction too.
- Advanced User Interaction: In the previous two chapters, you learned how to detect a rectangle, detect a QR code, display a plane over the detected rectangle and QR Code, and display content on that plane. In this chapter, you’ll learn how to improve the user interaction by using storyboards instead of standalone view controllers. You’ll also learn how to toggle fullscreen mode.
- Location Tracking and Beacons: In the previous three chapters, you learned how to use ARKit to implement a virtual billboard that was first triggered by a scan on a rectangle, and then later, a QR code. In the final chapter of this section, you’ll learn how you can use location features to enrich the user experience by automatically enabling features when the user is near the place of interest.
- Getting Started with Face-Based AR: With the introduction of the iPhone X and its TrueDepth front-facing camera, developers can create new and exciting apps and games where the user’s face can take center stage. In this section, you’ll create an app that create an app where the user can apply different selfie effects, such as masks. Over the next five chapters, you’ll be creating a face-based AR app named RW FaceCase.
- Tracking the User’s Face: In the last chapter, you updated the starter project so that it includes a face-tracking session and a mechanism to handle session errors and interruptions. In this chapter, you’ll take things a step further by adding the necessary code to track a user’s face.
- Creating Assets for Face-Based AR: In the last chapter, you updated the starter project and added code for tracking the user’s face. You also worked with face geometry and materials. But there’s a lot more to do with this project! If you haven’t created 3D content before, don’t freak out. You’ve got this! With SceneKit, you can create 3D designs right inside the SceneKit Scene file.
- Working with Blend Shapes: So you’ve added Woot Glasses and Pig to your app. Along the way, you learned how to make your own 3D assets inside of a SceneKit Scene file using only primitive shapes. If you thought that was cool, wait until you turn Pig into an Animoji — which is exactly what you’ll be doing in this chapter.
- Recording your AR Experience with ReplayKit: In the last chapter, you worked with blend shapes and added Pig to FaceCase. In this chapter, you’re going to add the ability to record and share your mask-wearing sessions using ReplayKit.
- Beginning Game Physics: You pretty much know everything there is to know about ARKit by this point in the book. So it’s only fitting to flex your SceneKit muscles a bit, and create something really cool. SceneKit has got your back, because there’s some pretty decent Vehicle Physics already built-in. In the next two chapters, you’ll learn how to create an awesome remote controlled monster truck!
- Advanced Game Physics: This chapter continues where the previous one left off. Most of the vehicle physics side of things have been configured. What’s left to do is to spawn the truck into existence, then make it drive and steer, and add a bit of polish!
- World Tracking & Persistent AR Experiences: So far, you’ve built a basic ARKit app that can render realistic virtual content in real-life environments. But wouldn’t it be cool to pick up where you left off each time? That’s what you’ll cover in this chapter.
- Shared AR Experiences: You’ve learned how to update the ARSketch app to persist AR world map data between different app runs. Now learn how to send that captured world map data to another device and restore a world map sent from a completely different device.
- Introducing USDZ & AR Quick Look: Learn about Apple’s new USDZ file format and walk through converting 3D models into this new, universal format. After converting, you’ll explore integrating AR Quick Look into your existing web pages and apps to enable them to display USDZ content in stunning augmented reality.
- Detecting Images & 3D Objects: If you need a word to describe this chapter, here it is: detection. You’ll learn how to detect 2D images and track their position when moving. You’ll also take a look at how to detect 3D objects.
