To display a 3D object using RealityKit in a macOS app, you can follow these general steps:
-
Import RealityKit: Ensure that your project includes the RealityKit framework. You can do this by importing RealityKit at the top of your Swift file.
-
Load a 3D Model: You can use RealityKit to load a 3D model in USDZ format. You can create or obtain a USDZ file using tools like Reality Composer or convert other 3D formats using the built-in conversion tools in macOS Preview.
-
Set Up an ARView: Create an ARView, which is a view that displays augmented reality content. This view will be the container for your 3D content.
-
Add the 3D Model to the Scene: Use RealityKit's APIs to add the 3D model to the ARView's scene. You can create an
Entityfor your model and add it to the scene's anchor. -
Customize the Appearance: You can use RealityKit's APIs to customize the appearance of your 3D model, such as applying materials and textures. RealityKit 4 provides new APIs for rich materials and virtual lighting, which can enhance how your 3D objects appear.
