Question 1

How do I load a 3D model from a URL using Insert3D?

Accepted Answer

Set the model.mesh and model.texture properties to URL strings, as Insert3D supports dynamic loading. For example, use model.mesh = 'https://example.com/model.obj' to fetch and display models at runtime, as explained in the Load via URL section.

Question 2

Insert3D vs SceneKit: which is better for a simple 3D viewer?

Accepted Answer

Insert3D is ideal for quick integration with minimal code, as it abstracts SceneKit's complexity. However, if you need advanced graphics features like particle systems or custom shaders, raw SceneKit might be necessary despite the steeper learning curve.

Question 3

Can Insert3D handle USDZ files for AR apps?

Accepted Answer

No, Insert3D currently only supports OBJ format models, as stated in the README. For USDZ files or AR integration, you'd need to use Apple's ARKit or other specialized libraries.

Question 4

How to change the rotation speed of a model in Insert3D?

Accepted Answer

Adjust the model.rotationSpeed property to a value in seconds for a full rotation. For instance, setting model.rotationSpeed = 5 rotates the model once every 5 seconds, as shown in the model configuration example.

Question 5

Is Insert3D compatible with SwiftUI or only UIKit?

Accepted Answer

The README examples use UIKit (e.g., view.Insert3D()), and there's no mention of SwiftUI support. It's likely designed for UIKit-based apps, so integrating with SwiftUI may require wrapping in UIViewControllerRepresentable.

Question 6

How to center a 3D viewer on the screen with Insert3D?

Accepted Answer

Calculate the x position using Int(UIScreen.main.bounds.size.width*0.5) - viewer.width/2, as suggested in the README for relative positioning, then set viewer.x to this value for center alignment.
