Building a Portal App in ARKit: Adding Objects

Where to Go From Here?

This has been quite a ride! Here’s a summary of what you learned in this tutorial:

• You can now detect and handle ARSession interruptions when the app goes to the background.
• You understand how hit testing works with an ARSCNView and the detected horizontal planes in the scene.
• You can use the results of hit testing to place ARAnchors and SCNNode objects corresponding to them.

In the upcoming final part of this tutorial series, you’ll pull everything together, add the walls and ceiling, and add a bit of lighting to the scene!

ARKit is Apple’s mobile AR development framework. With it, you can create an immersive, engaging experience, mixing virtual 2D and 3D content with the live camera feed of the world around you.

If you’ve worked with any of Apple’s other frameworks, you’re probably expecting that it will take a long time to get things working. But with ARKit, it only takes a few lines of code — 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 book, you’ll create five immersive and engaging apps: a tabletop poker dice game, an immersive sci-fi portal, a 3D face-tracking mask app, a location-based AR ad network, and monster truck simulation with realistic vehicle physics.

And, as part of AR/VR Week, it’s currently on sale. But don’t wait too long, as this deal is only good until Friday, March 29th!
