`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.

## Install
The go version I used is `Go 1.16`.
```bash
go get github.com/jdxyw/generativeart
```
## Art Type
```go
NewCircleLine(step float64, lineNum int, radius, xaixs, yaixs float64)
NewCircleLoop(radius float64)
NewMaze(step int)
NewRandCicle(mc, msp int, minStep, maxStep, minr, maxr float64, isRandColor bool)

```
## Docs
You could find the docs in the [doc](./docs).
## Examples
You could find examples for all types under [example](./example).
## General Options
```go
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.

## TODO
- Add more kinds of generative arts or types.
## 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.
