Overview ¶
Package random contains functions, MakeXXX, that can be used to create a random texture tree.
The following code creates a random tree up to six nodes deep and uses it to render to an 800x800 image, which is then saved as "example.png"
package main
import (
"github.com/jphsd/graphics2d/image"
"github.com/jphsd/texture"
"github.com/jphsd/texture/random"
)
func main() {
cf := random.MakeColorField(6, 0)
img := texture.NewRGBA(800, 800, cf, 0, 0, 1, 1)
image.SaveImage(img, "example")
}
