What was not announced but cool

While there were many exciting announcements at WWDC, some cool features that were mentioned but not deeply covered include:

1. Low-Level Mesh and Texture Access: RealityKit now provides low-level access for constructing and updating mesh and texture resources, which can be very powerful for developers needing fine-grained control over their 3D models. (Discover RealityKit APIs for iOS, macOS and visionOS)

2. Animation System Enhancements: The animation system in RealityKit has been significantly improved, allowing for the creation of animation timelines and more complex animations. (Discover RealityKit APIs for iOS, macOS and visionOS)

3. Billboard Component: This new component in RealityKit ensures that entities always face the user, which can be useful for creating more engaging and interactive experiences. (Discover RealityKit APIs for iOS, macOS and visionOS)

4. Pixel Cast: This feature enables pixel-perfect entity selection through a rendering-based approach, enhancing precision in user interactions. (Discover RealityKit APIs for iOS, macOS and visionOS)

5. Subdivision Surface: This allows for rendering smooth surfaces without creating a dense mesh, which can improve performance and visual quality. (Discover RealityKit APIs for iOS, macOS and visionOS)

6. Video Docking in Reality Composer Pro: This feature allows for the integration of video content within 3D environments, enhancing the interactivity and richness of the content. (Compose interactive 3D content in Reality Composer Pro)

7. Deploying to Multiple Platforms: Reality Composer Pro now supports deployment to iOS, macOS, and visionOS, making it easier to create cross-platform 3D content. (Compose interactive 3D content in Reality Composer Pro)

These features, while not the headline announcements, offer powerful new tools and capabilities for developers to create more immersive and interactive experiences.
