Coracle is a portable generative/art/sketch playground written in Kotlin

Web Demos  Android Demo  Articles

Getting Started

Everything happens in Jetbrains IDEA, clone the Coracle repository and open the web or Android project.

Note. There did used to be a Korge implementation but it was flawed and inefficient so I've removed it, but if you have a little time creating a JVM implementation of the Coracle Renderer should be straightforward.

Structure

Coracle uses the same basic sketch pattern as Processing, you initialise state in setup(), then mutate values and update the screen in draw()

    class MyDrawing: Drawing() {
    
        override fun setup() {
            //Setup state
        }
    
        override fun draw() {
            //Draw in the main draw loop
        }
    }
        

Primitives

Inbuilt Objects

Line  Circle  Point  Bezier

Also: CatmullRomSpline, Colour, Polyline, Rect

Why not just use Processing?

I think in Kotlin and I wanted something ridiculously lightweight that could still be used to create advanced animations.

Goals/Non Goals

• Goals: Have fun, experiment.
• Non Goals: performance, correctness, everything else.

License

You probably don't want to use this, it was an itch I needed to scratch and there will be no support whatsoever.

I've not decided on a license yet, but if you think it was okay for the FSF to readmit Richard Stallman you can't use it.

Important

Trans rights are human rights, this framework kills fascists
