Mandelbrot Orbits
This is a small project to learn Rust.
It generates an image of the Mandelbrot Set where each pixel color represents the period of the complex point if the point belongs to the Set.
More info about Mandelbrot Set Periods.
You can render it in greyscale.
Or the colorized version.
With a different color depending on the period.
Requirements
cargo:^1.62.1.rustc:^1.62.1.
Use
git clone git@github.com:josecelano/mandelbrot-orbits-rust.git
cargo run ./output/mandelbrot_2048x2048.png 2048x2048 -2.0,2.00 2.0,-2.0Development
Execute MegaLinter locally:
./bin/ml.shRun tests:
cargo testMath
You can find an explanation here.
And I'm trying to find and write a more formal explanation of the math behind the algorithm.

- Jeremy Rifkin pointed me to the solution. I have copied/pasted part of his code to detect the period.
