Types

type Fractal

type Fractal interface {
	fmt.Stringer

	// Intensity determines the pixel value of the given
	// coordinates.
	Intensity(x, y float64) uint8

	// ArgHelp provides a help string for use in the UI,
	// telling the user what the arguments to that fractal
	// represent.
	ArgHelp() string
}

Fractal is the interface that decouples the driver program from the particular fractal being rendered.

func NewJuliaExp

func NewJuliaExp(c complex128, depth int, escape float64) Fractal

Returns a new Fractal which computes the Julia variation: e^x + c.

func NewJuliaSq

func NewJuliaSq(c complex128, depth int) Fractal

Returns a new Fractal which computes the Julia variation: x^2 + c.

func NewJuliaZExp

func NewJuliaZExp(c complex128, depth int, escape float64) Fractal

Returns a new Fractal which computes the Julia variation: x*e^x + c.

func NewMandelbrot

func NewMandelbrot(depth int) Fractal

Returns a new Fractal which computes the standard mandelbrot set: x^2 + location.
