The content you add to the window and volume stays contained within its bounds to allow sharing the space with other applications. The game can be played while keeping a Safari window open to read up on winning strategies. Inside a Shared Space, your app can open one or more windows to display content.Īdditionally, your app can create a three-dimensional volume.įor example, now you can show a list of available board games in one window, the rules in another, and open the selected game in its own volume. The Shared Space is where apps exist side by side, much like multiple apps on a Mac desktop. You can now display UI, including windows and three-dimensional content, anywhere around you.īy default, applications on this platform launch into the Shared Space. Here is an example from our Hello World sample app. This platform offers new ways to present your application that you'll want to consider as you bring your iOS experience over. Spatial computing allows you to take your iOS AR experience and expand it beyond the window. Lets get into preparing to migrate your experience for spatial computing. We'll show an example of how to combine ARKit data and RealityKit to enable raycasting for spatial computing.Īnd finally, we'll review the updates to ARKit and see the new ways to utilize familiar concepts from iOS. Raycasting is something many iOS applications use to place content. Then, we'll talk about the different ways your app can bring content into people's surroundings. We'll see how RealityView lets your app leverage spatial computing similar to ARView on iOS. Next, we will talk about Reality Kit, which is the engine to use to render and interact with your content. Let's get started! First, we'll explore some new ways you can present your app for spatial computing, and introduce new content tools available to you. We're going to cover how these concepts have carried over, how they've evolved, and how you can take advantage of them. This is a great opportunity to reimagine your app and AR experience for spatial computing.Īs a part of this transition, you'll be using familiar concepts that we've introduced with ARKit and RealityKit. In order to take advantage of all the new capabilities and immersive experiences this new platform offers, you'll need to update your iOS ARKit-based experience. Here is an example demonstrating these capabilities, along with new ones introduced with this platform.įor example, ARKit now provides hand tracking to your app, which allows people to reach out and directly interact with virtual content that can then interact with their surroundings. We believe that this will free you up to focus on building the best application and content possible for this platform. The system takes on responsibilities that used to belong to applications.Ĭamera pass-through and matting of the user's hands are now built-in, so your application gets these capabilities for free.Īnother built-in capability is that ARKit world maps are continuously persisted by a system service, so your application doesn't need to do it anymore. To enable spatial computing, ARKit and RealityKit have matured and are deeply integrated into the operating system.įor example, ARKit's tracking and Scene Understanding are now running as system services, backing everything from window placement to spatial audio. We then introduced RealityKit, laying out the foundation for an engine capable of highly realistic physically-based rendering and accurate object simulation with your surroundings. Initially, we started with a SceneKit view to use ARKit's camera transforms and render 3D content on iOS. Using the provided geometry and semantic knowledge, your content can be intelligently placed and realistically interact with surroundings.įinally, rendering engines can correctly register and composite your virtual content over captured images utilizing camera transforms and intrinsics provided by ARKit. Scene understanding provides insight about the real world around you. This allows anchoring virtual content with a position and orientation to the real world. With world tracking, ARKit is able to track your device's position in the world with six degrees of freedom. Oliver and I are engineers on the ARKit team and we are thrilled to review the concepts - some familiar and some new - that you'll need know about when bringing your iOS AR app to our new platform.ĪRKit was introduced on iOS in 2017 and with it, we introduced three key concepts to building augmented reality applications. ♪ Mellow instrumental hip-hop ♪ ♪ Omid Khalili: Hello!
