To use RealityKit in 2D, you can leverage the new APIs introduced at WWDC 2024. Specifically, the session "Build a spatial drawing app with RealityKit" provides a comprehensive guide on how to integrate RealityKit's capabilities with SwiftUI and ARKit to create a spatial drawing app. Here are some key points from the session:
-
Set up Spatial Tracking: This allows the app to understand hand and environment data, which is crucial for spatial interactions.
-
Build a Spatial User Interface: Use SwiftUI to create an interactive UI for customizing brushes and styles.
-
Generate Brush Geometry: Create customized meshes, textures, and shaders to achieve a polished visual design.
-
Import 2D Vector Graphics: Use new APIs to import 2D vector graphics and make them spatial.
For more detailed information, you can refer to the session "Discover RealityKit APIs for iOS, macOS and visionOS," which covers various new features and enhancements in RealityKit, including how to enhance your spatial computing app.
