SCNLight | Ask WWDC

The SCNLight class is part of SceneKit, which is a high-level 3D graphics framework. However, the context provided focuses on RealityKit and other related APIs presented at WWDC 2024. Here are some relevant details about lighting in RealityKit, which might be useful if you are looking for similar functionalities:

Types of Lights in RealityKit:
- Spotlight: Illuminates objects in a cone-shaped volume. Supports customizing its angle, distance, and attenuation. Can cast shadows.
- Directional Light: Lights up all objects in a scene uniformly. Can cast shadows.
- Point Light: Emits light in all directions from a single point. Supports customizing attenuation radius and fall-off exponent.
You can find more about these lights in the session Discover RealityKit APIs for iOS, macOS and visionOS.
Adding Lights in RealityKit:
- Lights can be added through Swift API in code or through Reality Composer Pro, which offers a UI for tuning lighting behavior.
- Example: Attaching a spotlight to a spaceship entity, setting its color, intensity, and attenuation radius, and enabling shadows.
Detailed steps are available in the session Discover RealityKit APIs for iOS, macOS and visionOS.
Environment Lighting:
- RealityKit supports environment probes to approximate lighting in your physical environment.
- You can use an environment lighting configuration component to control how much lighting an entity receives from the environment probe.
More information can be found in the session Discover RealityKit APIs for iOS, macOS and visionOS.
Lighting in Custom Environments:
- VisionOS allows for customizing the tint and brightness to blend well with your environment lighting, enhancing immersion.
This is discussed in the session Enhance the immersion of media viewing in custom environments.
