RealityKit

RealityKit is a key framework discussed at WWDC 2024, designed to simplify the process of rendering 3D models and creating spatial experiences. Here are some highlights from the sessions:

1. Platforms State of the Union:

   • RealityKit simplifies rendering 3D models with various styles like realistic, cel-shaded, or cartoon. It first shipped with Vision Pro and has gained significant new capabilities, including alignment across macOS, iOS, and iPadOS with RealityKit 4. This includes features like material X, portals, particles, rich materials, virtual lighting, blend shapes, inverse kinematics, and animation timelines. (Platforms State of the Union)

2. What’s new in USD and MaterialX:

   • RealityKit supports USD and MaterialX, enabling the creation of amazing spatial experiences. New features include support for MaterialX shaders in Shader Graph, which is now available across VisionOS, iOS, iPadOS, and macOS. (What’s new in USD and MaterialX)

3. Build a spatial drawing app with RealityKit:

   • This session demonstrates building an interactive spatial drawing app using RealityKit. It covers spatial tracking APIs, SwiftUI for spatial UI, resource updates, low-level APIs for generating meshes and textures, and importing 2D vector graphics to make them spatial.

4. Explore object tracking for visionOS:

   • This session shows how to use RealityKit and ARKit APIs for object tracking in visionOS, including creating and anchoring virtual content with Reality Composer Pro. (Explore object tracking for visionOS)

5. Break into the RealityKit debugger:

   • This session introduces the RealityKit debugger, which helps track down bugs by taking a 3D snapshot of your running app and loading it in Xcode for exploration. (Break into the RealityKit debugger)

6. Discover RealityKit APIs for iOS, macOS, and visionOS:

   • This session covers new RealityKit APIs for developing spatial computing apps, including enhancements like portal crossing, dynamic lights, and cross-platform capabilities. (Discover RealityKit APIs for iOS, macOS and visionOS)
