cc := generativeart.NewColorCircle2(30)
```
## Dot Line
2021-03-09 06:43:22 +00:00
`dot line` would draw images with the short dot and short. The short lines would compose as a big circle.
2021-03-08 07:56:32 +00:00
### parameters
2021-03-09 06:43:22 +00:00

2021-03-08 07:56:32 +00:00
- ras/canv: Control the appearance of this image.
2021-03-09 06:43:22 +00:00
- randColor: Use the specified color or random colors.
2021-03-08 07:56:32 +00:00
```go
dl := generativeart.NewDotLine(100, 20, 50, false)
```
## Random Shape
`random shape` would draw images with random shapes. The whole image would rotate with some degree.
### parameters
- shapeNum: It indicates how many shapes you want to draw.
```go
rs := NewRandomShape(150)
```
## Janus
2021-03-09 06:08:33 +00:00
`Janus` would draw an image with multiple circles split at its center with random noise in the horizontal direction.

### TODO
### parameters
2021-03-09 06:08:33 +00:00
## Contour Line
2021-03-09 06:43:22 +00:00
`Contour Line` uses the `perlin noise` to do some flow field.
2021-03-09 06:08:33 +00:00
### parameters
- lineNum: It indicates how many lines.
2021-03-08 07:56:32 +00:00
## Silk Sky
2021-03-09 06:08:33 +00:00
`Silk Sky` would draw an image with multiple circles converge to one point or one circle.
2021-03-08 07:56:32 +00:00
### parameters
- circleNum: The number of the circles in this drawing.
- sunRadius: The radius of the sun. The sun is a point/circle where other circles meet.
```go
silkSky := NewSilkSky(circleNum int, sunRadius float64)
```
## Julia
`Julia` is to draw a `Julia Set` . [Julia Set ](https://en.wikipedia.org/wiki/Julia_set ) is a math concept. You can define your own formula in this package.
### parameters

2021-03-09 06:08:33 +00:00
- xaixs, yaixs: The range for the X-Y coordination used to mapping the julia set number to the real pixel of the image. These should be positive. It only indicates the first quadrant range.
2021-03-08 07:56:32 +00:00
```go
func julia1(z complex128) complex128 {
c := complex(-0.1, 0.651)
z = z*z + c
return z
}
julia := generativeart.NewJulia(julia1, 40, 1.5, 1.5)
```
2021-03-09 11:07:47 +00:00
## Noise Line
`Noise Line` draws some random line and circles based on `perlin noise` .
### parameters
- n: The number of random line.
```go
nl := generativeart.NewNoiseLine(1000)
```
2021-03-10 03:58:56 +00:00
## Ocean Fish
2021-03-11 03:24:14 +00:00
