SwiftyCreatives
Creative coding library for Swift.
Using Metal directly for rendering.
Sample Code
Main sketch process
final class MySketch: SketchBase {
var boxes: [Box] = []
var elapsed: Float = 0.0
func setup() {
for _ in 0...100 {
let box = Box()
box.setColor(f4.randomPoint(0...1))
box.setPos(f3.randomPoint(-10...10))
box.setScale(f3.one * Float.random(in: 0.3...3))
boxes.append(box)
}
}
func update() {
for b in boxes {
b.setColor(f4(sin(elapsed), b.color.y, b.color.z, b.color.w))
}
elapsed += 0.01
}
func cameraProcess(camera: MainCamera<some CameraConfigBase>) {
camera.rotateAroundY(0.01)
}
func draw(encoder: MTLRenderCommandEncoder) {
for b in boxes {
b.draw(encoder)
}
}
}Configs (optional)
final class MyDrawConfigNormal: DrawConfigBase {
static var contentScaleFactor: Int = 3
static var blendMode: SwiftyCreatives.BlendMode = .normalBlend
}
final class MyDrawConfigAdd: DrawConfigBase {
static var contentScaleFactor: Int = 3
static var blendMode: SwiftyCreatives.BlendMode = .add
}
final class MyDrawConfigAlpha: DrawConfigBase {
static var contentScaleFactor: Int = 3
static var blendMode: SwiftyCreatives.BlendMode = .alphaBlend
}You can use SketchView as SwiftUI View
ZStack {
Text("Swifty-Creatives Example")
.font(.largeTitle)
VStack {
HStack {
SketchView<MySketch, MainCameraConfig, MainDrawConfig>()
SketchView<MySketch, MainCameraConfig, MainDrawConfig>()
SketchView<MySketch, MainCameraConfig, MainDrawConfig>()
}
HStack {
SketchView<MySketch, MainCameraConfig, MyDrawConfigNormal>()
SketchView<MySketch, MainCameraConfig, MyDrawConfigAdd>()
SketchView<MySketch, MainCameraConfig, MyDrawConfigAlpha>()
}
}
}
