The question "Why is the sky blue?" is off-topic for the content presented by Apple at WWDC. However, I can provide information on relevant topics discussed at WWDC.
For example, if you are interested in optimizing 3D assets for spatial computing, you might find the session Optimize your 3D assets for spatial computing particularly useful. This session covers topics such as setting up a sky dome, which is crucial for creating immersive environments in spatial computing.
Additionally, if you are interested in maintaining color consistency across different lighting conditions in photography, the session Keep colors consistent across captures provides valuable insights into the Constant Color API and how it helps achieve consistent color rendering.
Here is a list of the sessions mentioned in the context:
- Optimize your 3D assets for spatial computing
- Keep colors consistent across captures
- Discover RealityKit APIs for iOS, macOS and visionOS
Feel free to ask more specific questions about these sessions or any other WWDC content!

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.

Keep colors consistent across captures
Meet the Constant Color API and find out how it can help people use your app to determine precise colors. You’ll learn how to adopt the API, explore its scientific and marketing potential, and discover best practices for making the most of the technology.

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.
