      Effect:Fractal, Mandelbrot
      Category:Procedural Sources
      Speed:Medium

      Description: The Fractal Mandelbrot Effect lets you create fractal patterns based on the Mandelbrot Set function. Fractals are self-repetitive surfaces. The Mandelbrot Set is a particularly nice and easy to control fractal which is highly self-similar at various scales.

      Fractal Mandelbrot uses the incoming Color 1 and Color 2 to create the Effect. The external area of the Effect (non-mandelbrot area) is drawn in Color 1, and the Mandelbrot Fractal part of the Effect is drawn in Color 2.

      If you enable the Fit To Brush Option you will paint with the Fractal Mandelbrot Effect sized to your brush.

       
      Options: The Fractal Mandelbrot Effect has the following Options Pane:

      Scale:This value controls how zoomed in or out of the fractal surface.
      Complexity:The Complexity value sets the amount of detail that is imparted to the fractal edges. Since fractals are self-replicating this controls how detailed that process is. Note that of any of the values, setting this to high numbers will significantly slow down painting.
      X Center:This controls where on the fractal surface the X Center of the Canvas is. This effectively pans the fractal in the X direction.
      Y Center:This controls where on the fractal surface the Y Center of the Canvas is. This effectively pans the fractal in the Y direction.
      Color Span:This controls the amount of colors that are generated between Color 1 and Color 2 while creating the Effect. The lower the value, the less colors are generated.
      Fit To Brush:If set to a Red X the Effect spans the screen such that as you paint you reveal the Effect. When set to a Green Check Mark the Effect is sized to the brush such that as you paint the entire Effect is within the brush itself.
      Output Color 1:By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.
      Output Color 2:By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.

      Example: The following image shows the Fractal Mandelbrot with its default settings. Color 1 is White and Color 2 is Black:

      Here we have zoomed the Fractal out so the entire Mandelbrot set is visible:

      In this next image, we use three Effects together. Remember that Fractal Mandelbrot uses Color 1 and Color 2. Color 1 is set to a dark cyan. In Slot 1 we placed the Clouds, Marble, Granite Effect with Output Color 1 set to Add. In Slot 2 we placed the 3-Color Gradient, set it to Horizontal, set Output Color 1 to Ignore, and Output Color 2 to Replace. In Slot 3 we placed our Fractal Mandelbrot effect:
