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