Create 3D models with Object Capture

6:56 - Creating a PhotogrammetrySession with a folder of images

import RealityKit

let inputFolderUrl = URL(fileURLWithPath: "/tmp/Sneakers/", isDirectory: true)
let session = try! PhotogrammetrySession(input: inputFolderUrl,
                                         configuration: PhotogrammetrySession.Configuration())

9:26 - Creating the async message stream dispatcher

// Create an async message stream dispatcher task

Task {
    do {
        for try await output in session.outputs {
            switch output {
            case .requestProgress(let request, let fraction):
                print("Request progress: \(fraction)")
            case .requestComplete(let request, let result):
                if case .modelFile(let url) = result {
                    print("Request result output at \(url).")
                }
            case .requestError(let request, let error):
                print("Error: \(request) error=\(error)")
            case .processingComplete:
                print("Completed!")
                handleComplete()
            default:  // Or handle other messages...
                break
            }
        }
    } catch {
       print("Fatal session error! \(error)")
    }
}

13:44 - Calling process on two models simultaneously

try! session.process(requests: [
    .modelFile("/tmp/Outputs/model-reduced.usdz", detail: .reduced),
    .modelFile("/tmp/Outputs/model-medium.usdz", detail: .medium)
])
