To learn more about +this correspondence, see the tutorial on the :tutor:`Julia set <julia.xaf>`. + +This function switches between Mandelbrot and Julia representations. When +switching to Julia, you need to set the seed--a point selected from the +Mandelbrot set. + +If you run this function from the menu, you are prompted for the Julia seed as +a number. Often, this can be clumsy, and it would be easier to specify a point +with the mouse pointer. If you hit the M key instead of using the menu, the +current mouse position is used. + +Good seedpoints lie at the boundaries of the Mandelbrot set; other seeds +usually generate quite a boring fractal. You can also explore various seeds at +high speed using the :ref:`Fast Julia mode <fastjulia>`. + +Not all fractals have Julias, but XaoS can generate fake Julia sets for those +that do not, which use some Julia-like modification of the formula; so this +function is currently usable for all fractal types. + +**Available as**: menu item + +**Syntax**:(julia bool) + +This function is used to enable/disable julia mode in animation files. + +**Available as**: command line option, command + +**Syntax**:(juliaseed complex) + +Select the current julia seed. + +**Available as**: command line option, command |
