Displaying a Model Asset

Learn how to add non-AR asset to your project using our Swift SDK.
Now that you have successfully integrated the echo3D SDK into Xcode, it's time to display a model in your project!
​Scene Kit is a rendering engine that allows you to develop native iOS and visioOS apps in Xcode.

Adding 3D content

Add a model asset through the console. Here's how:

Setting Up an Application

Construct an object of type Echo3D and use it to access Assets stored under your echo3D account's API Key.
Render your assets however you want.

Example Setup:

​
1
import SwiftUI
2
import SceneKit
3
​
4
struct ContentView: View { // Creates a SwiftUI View
5
var body: some View { // Creates a SwiftUI body
6
VStack {
7
Text("View Your Echo3D Model!")
8
.font(.headline)
9
​
10
SceneKitView()
11
.frame(width: 350, height: 350) // Adjust the size as needed
12
}
13
}
14
}
15
​
16
struct SceneKitView: UIViewRepresentable { // Creates the Scene with 3D Model using SceneKit and Echo3D Swift SDK
17
18
func makeUIView(context: Context) -> SCNView { // Creates a simple scene
19
let sceneView = SCNView()
20
sceneView.autoenablesDefaultLighting = true
21
sceneView.allowsCameraControl = true
22
return sceneView
23
}
24
​
25
func updateUIView(_ sceneView: SCNView, context: Context) { // Adds 3D Model stored under your Echo3D Accounts API Key
26
let e = Echo3D(); // Create an object of class Echo3D
27
28
e.queryDatabase(api_key: e.api_key, completion: { (entry_list) -> () in // Queries Echo3D's database for 3d Models
29
let entry = entry_list[0]
30
entry.downloadFile(completion: { (storage_id) in // Downloads the specificed 3D model entry and loads it into the scene
31
if let object = try? SCNScene(url: storage_id, options: nil) {
32
let objectNode = object.rootNode
33
sceneView.scene = object
34
sceneView.scene?.rootNode.addChildNode(objectNode)
35
}
36
});
37
});
38
}
39
}

@main

struct SDKTest2_6App: App {
43
var body: some Scene {

ContentView()
