Key Features

Processing-like Syntax

You can easily create your graphics, using Swift Programming Language with the intuitive essence of Processing.
I like how push() and pop() became super simple using Swift's trailing closure.

import SwiftyCreatives

final class MySketch: Sketch {
    override func draw(encoder: SCEncoder) {
        let count = 20
        for i in 0..<count {
            color(0.75, Float(i) / 40, 1, 0.5)
            push {
                rotateY(Float.pi * 2 / Float(count) * Float(i))
                translate(10, 0, 0)
                box(0, 0, 0, 1, 1, 1)
            }
        }
    }
}

struct ContentView: View {
    var body: some View {
        SketchView(MySketch())
    }
}

Apple Vision Pro - Immersive Space

Supports visionOS! You can dive in to your sketch with Immersive Space rendering!

ImmersiveSpace(id: "ImmersiveSpace") {
    CompositorLayer(configuration: ContentStageConfiguration()) { layerRenderer in
        let renderer = RendererBase.BlendMode.normalBlend.getRenderer(sketch: SampleSketch(), layerRenderer: layerRenderer)
        renderer.startRenderLoop()
    }
}

xib to 3D Space!

Create UIView with xib, and place it in 3D scene!
UIButton can be connected with IBAction, and can be tapped in 3d space.
