Go Go Report Card GitHub license

generativeart is a Go package to generate many kinds of generative art. The goal is to collect some excellent generative art (implemented in R or Processing), and rewrite them in Go again. I would paste the original link at the end of this README(If I remember, you can also submit a PR if you found I missed something.). Currently, it supports the following type.

Docs

You could find the docs in the doc.

Examples

You could find examples for all types under example.

General Options

type Options struct {
 background  color.RGBA
 foreground  color.RGBA
 lineColor   color.RGBA
 lineWidth   float64
 colorSchema []color.RGBA
 nIters      int
 alpha       int
}

The Options is a global option for the whole canva. It includes those general parameters used by different kinds of types, such as background, lineColor, and colorScheme.

For those parameters specified for different kinds of art types, they have their own struct.

Usage and example

Below are some selective examples. For more examples, you could check the example folder.

Contribution

Thanks for the following sites and repos, I got lots of ideas, inspiration, code, and tricks from them. The list would be very long; sorry for forgetting some of them.
