mandelbrot-rust

Implementing a Mandelbrot Image Generator (In Rust) (Agai... wait, this is my first time using Rust!)

Examples

mandelbrot-rust -w 4000 -h 4000 --x_mid=-1.25737518304050244765 --y_mid=0.378759463618701690545 -z 6800000000 -i 2040 -c 13

Structure

• main.rs contains the main function called upon startup (duh)
• cli.rs gets the values for the different parameters to use during computations (and providing default values if non are given)
• generator.rs creates the "raw" mandelbrot data, computing the iterations for every point of interest on the gaussian plane, using...
• ... mandelbrot.rs, which provides the function to check for a given complex value how many iterations it takes to exceed the threshold of 2^2 (=4)
• color_map.rs contains different color modes to map the raw mandelbrot data to RGB-values in the form of a vector in row-major order, with every triple of values forming the RGB values of a single pixel
• png_writer.rs then takes this vector and writes it to a PNG image file

Used crates / libraries

• num for handling complex numbers
• image for writing image data as PNGs
• clap for handling CLI option inputs
• little_exif for writing parameters as EXIF metadata

ToDo / Wishes

• Functionality to also generate images of julia sets
• More color modes / better CLI (currently using numbers - at least provide information about which color mode is which)
• Video generation capability
• Custom complex expression evaluation for mandelbrot sets (currently only fixed z = z^2 + c)
