NextFractal

In this example you will learn how to create the Mandelbrot set of z ^ m + w where exponent m is an integer.

fractal { // Set region margins and declare state vector as [x,n] where x and n are built-in variables orbit [<-1.5,-1.5>,<1.5,1.5>] [x,n] { // Iterate for n from 0 to 200 stopping when mod2(x) > 4 loop [0, 200] (mod2(x) > 4) { x = x ^ 5 + w; } } // Set background color to alpha=1, red=1, green=1, blue=1 color [(1,0,0,0)] { // Create palette with 200 colors and name gradient palette gradient { [#FFFF0000 > #FFFFFFFF, 10]; [#FFFFFFFF > #FFFFFFFF, 190]; } // Apply rule when n > 0 and set opacity to 1.0 rule (n > 0) [1] { // Set color to element n - 1 of gradient (gradient has 200 colors starting from index 0) gradient[n - 1] } } }

Execute the script above in NextFractal and you will get the image below:
