Swift3D 📐🔷

📐🔷 Swift3D is a custom 3D engine used to define and render 3D scenes inside of existing 2D UI with declarative code.

Using a custom DSL or Domain Specific Language that looks and feels like SwiftUI, you can define complex 3D scenes with custom lighting, transitions, and shaders.

💪 This engine uses the power of Metal, Apple's low-level graphics API, to drive your 3D experiences, making them fast and responsive. With the combination of SwiftUI + Metal, you can create really unique visual effects and animations.

Here are just a few examples of the types of things you can do.

Installation

Swift 3D uses Swift Package Manager for installation. Please follow Apple's Tutorial using the URL for this repository.

In Xcode, select “File” → “Add Packages...”
Enter https://github.com/andrewzimmer906/Swift3D.git.

Or you can add the following dependency to your Package.swift:

.package(url: "https://github.com/andrewzimmer906/Swift3D.git", from: "1.0.0")

🚀 Usage

📖 Check out the Demo project for usage examples and code.

Swift3D is a 3D engine that seamlessly integrates with SwiftUI, allowing you to create immersive 3D experiences using its custom DSL.

The system supports:

*.usdz/*.obj Model Loading
Primitive Shapes
Custom Lighting and Shaders
Custom Transitions and animations
Integration with CMMotion for IMU driven experiences

To get started, add a Swift3DView to your SwiftUI View, and start building your 3D scene.

Here's a basic example that renders a cube:

struct aView: View {
var body: some View {
	Swift3DView {
	      CameraNode(id: "mainCam")
	        .translated(.back * 3)
	        
	      CubeNode(id: "cube")
	        .shaded(.unlit(.red))
	    }
    }
}

For more advanced usage, the Demo.xcodeproj includes additional examples covering custom lighting, model loading, update loops, camera controls, and transitions. 🌟
