To use Metal with RealityKit, you can integrate Metal's rendering capabilities into your RealityKit projects to achieve custom rendering effects or to optimize performance. Here are some key points from the WWDC sessions that might help you:
-
Rendering with Metal on visionOS: You can render directly with Metal on visionOS if you need a custom rendering pipeline. This is particularly useful if porting your game or app to RealityKit is not practical. You can run your app in a window, similar to how it would behave on an iPad, allowing it to run alongside other apps in a shared space. For more details, refer to the session Bring your iOS or iPadOS game to visionOS.
-
Metal with Passthrough in visionOS: This session covers how to use Metal APIs along with ARKit and compositor services to create a mixed immersive experience. It involves blending your app's rendered content with the physical surroundings and improving the positioning of rendered content. For more information, see Render Metal with passthrough in visionOS.
-
Low-Level Mesh and Textures: RealityKit now offers new APIs for low-level mesh and textures that work with Metal compute shaders. This provides improved control over how your apps look, enabling fully dynamic models and textures in every frame on visionOS. This is discussed in the Platforms State of the Union.
These sessions provide a comprehensive overview of how you can leverage Metal within RealityKit to enhance your app's rendering capabilities.
Explore object tracking for visionOS
Find out how you can use object tracking to turn real-world objects into virtual anchors in your visionOS app. Learn how you can build spatial experiences with object tracking from start to finish. Find out how to create a reference object using machine learning in Create ML and attach content relative to your target object in Reality Composer Pro, RealityKit or ARKit APIs.
Optimize your 3D assets for spatial computing
Dive into an end-to-end workflow for optimized 3D asset creation. Discover best practices for optimizing meshes, materials, and textures in your digital content creation tool. Learn how to harness shader graph, baking, and material instances to enhance your 3D scene while optimizing performance. Take advantage of native tools to work more effectively with your assets and improve your app’s performance.
Platforms State of the Union
Discover the newest advancements on Apple platforms.
Discover RealityKit APIs for iOS, macOS and visionOS
Learn how new cross-platform APIs in RealityKit can help you build immersive apps for iOS, macOS, and visionOS. Check out the new hover effects, lights and shadows, and portal crossing features, and view them in action through real examples.
Render Metal with passthrough in visionOS
Get ready to extend your Metal experiences for visionOS. Learn best practices for integrating your rendered content with people’s physical environments with passthrough. Find out how to position rendered content to match the physical world, reduce latency with trackable anchor prediction, and more.
Build a spatial drawing app with RealityKit
Harness the power of RealityKit through the process of building a spatial drawing app. As you create an eye-catching spatial experience that integrates RealityKit with ARKit and SwiftUI, you’ll explore how resources work in RealityKit and how to use features like low-level mesh and texture APIs to achieve fast updates of the users’ brush strokes.
Bring your iOS or iPadOS game to visionOS
Discover how to transform your iOS or iPadOS game into a uniquely visionOS experience. Increase the immersion (and fun factor!) with a 3D frame or an immersive background. And invite players further into your world by adding depth to the window with stereoscopy or head tracking.
