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.
- generativeart
- Table of Contents
If you found this package is useful, maybe you could buy me a coffee from Paypal.
I am glad to see someone to contribute to this repo, please follow the CONTRIBUTING.md for more information. Or you can just open an issue or PR.
This package is still working in progress. More types would be added. Welcome anyone interested in this field to submit your PR.
- Maze
- Julia Set
- Random Circle Trails
- Silk Smoke
- Spiral Square
- Square Grid

For these kinds of art, the package provides as many parameters to control the appearance.
The go version I used is Go 1.16.

NewDomainWrap(scale, scale2, xOffset, yOffset float64, cmap ColorMapping)
NewPerlinPerls(circleN, dotsN, colorMin, colorMax int)You could find the docs in the doc.
You could find examples for all types under example.
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.
Below are some selective examples. For more examples, you could check the example folder.

- Add more kinds of generative arts or types.
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.
