Overview

Brots are generalization of Mandelbrot that takes a generic Mandelbrot equation. This library makes every part of the Mandelbrot equation as a parameter offering extreme flexibility to override or use the default implementation.

An equation means nothing to me unless it expresses a thought of God. — Srinivasa Ramanujan

A Standard Mandelbrot equation,

when implemented and rendered will look like this,

mandel = MandelBrot() # Initialize Mandelbrot
matplot_renderer = MatplotJupyterRenderer() # Initialize the renderer

mandel.iterate_diverge(max_iterations=25) # Run the iterate diverge loop
matplot_renderer.plot(mandel, cmap="RdGy") # Plot the results

We can further zoom in on the coordinates and iterate-diverge on those coordinates,

mandel.set_boundaries((-0.02, 0.02), (0.780, 0.820)) # Zoom in on the coordinates
mandel.iterate_diverge(max_iterations=100)
matplot_renderer.plot(mandel, cmap="plasma")

will render like below,

By changing each part of the equation you can get a range of generation. Generalizing the above Mandelbrot equation to k, we get Multibrot where,

For a K value of 3 we get a Multibrot rendered like this,

multi = MultiBrot()

multi.iterate_diverge(max_iterations=15)
matplot_renderer.plot(multi, cmap="binary")

A Tricorn brot is expressed as,

tricorn = UserBrot(brot_equation=tricorn_brot_equation)

tricorn.iterate_diverge(max_iterations=15)
matplot_renderer.plot(tricorn, cmap="RdYlBu")

A Burning ship brot is expressed as,

burning_ship = UserBrot(brot_equation=burning_ship_brot_equation)

burning_ship.iterate_diverge(max_iterations=15)
matplot_renderer.plot(burning_ship, cmap="copper")

JuliaBrot is an extension to Mandelbrot, in which instead of initializing Z and C as 0 and complex(i, j) respectively we initialize Z as complex(i, j) and C as a function f(i, j) based on the julia set that we want to generate.

For example, to generate a `` julia set we initialize C as complex(-0.7, 0.35) and this generates the following,

julia = JuliaBrot(julia_name="frost_fractal")
julia.iterate_diverge(max_iterations=100)

matplot_renderer.plot(julia, cmap="inferno")

julia = JuliaBrot(julia_name="galaxiex_fractal")
julia.iterate_diverge(max_iterations=100)

matplot_renderer.plot(julia, cmap="inferno")
