The best way to use a directional light in RealityKit involves understanding its properties and how it interacts with other elements in your scene. Here are some key points:
-
Illumination: A directional light illuminates all objects in a scene uniformly, simulating a distant light source like the sun. This is useful for creating consistent lighting across your entire scene.
-
Customization: You can customize the color and intensity of the directional light. This allows you to match the lighting to the mood and style of your scene.
-
Shadows: Directional lights can cast shadows, which can add depth and realism to your scene. However, rendering shadows can be computationally expensive, so it's important to check your app's performance frequently.
-
Implementation: You can add and configure directional lights either through Swift API in code or using Reality Composer Pro, which provides a UI for tuning lighting behavior.
For a practical example of how to add and configure lights in RealityKit, you can refer to the session Discover RealityKit APIs for iOS, macOS and visionOS.
