init(from:configurations:)

Declaration

nonisolated init(from catalog: Entity.ConfigurationCatalog, configurations: [String : String]? = nil) where Content == ResolvedModel3D

Parameters

• catalog:

  A collection of alternative representations for an entity.

• configurations:

  A dictionary of configuration choices the initializer applies as it loads the entity, mapping the ID of a configuration set to the ID of a configuration within that set.

Discussion

Until the model loads, Model3D displays a default placeholder. When the load operation completes successfully, Model3D updates the view to show the loaded model. If the operation fails, Model3D continues to display the placeholder. The following example loads and displays a model from an example server:

let configCatalog = try await Entity.ConfigurationCatalog(from: url)
...
Model3D(from: myConfigurationCatalog,
        configurations: ["size": "small", "color": "red"])

If you want to customize the placeholder or apply ResolvedModel3D-specific modifiers — like ResolvedModel3D/resizable() — to the loaded model, use the init(from:configurations:content:placeholder:) initializer instead.
