#Mandelbrot

Mandelbrot fractal generator and viewer. Uses the SFML (sfml-dev.org) and rust-sfml (rust-sfml.org) to generate and display the image.

##Installation

Works on Linux 64bits (only tested on Debian Jessie - amd64), but it should work on most OS.

###Prerequisites

Make sure you've installed SFML and CSFML 2.0 (available on sfml-dev.org). You should also install the latest rustc and Cargo version (rust-sfml.org).

###Download and install

1. Download the git package (either with git clone or in zip format).
2. Extract here (if it's a zip) and go in the directory (the one called rust-mandelbrot).
3. Type cargo build to build it, and cargo build --release to have some optimizations.
4. Launch it with cargo run.

##Use

You can use rust-mandelbrot with two commands :

###generate

The generate command create a Mandelbrot Set into an image file, using the Image SFML object. The command takes 4 arguments : the panel of the Set you want to render, the image dimensions, the max iterations to compute the Set's points and the path of the image file.

$ rust-mandelbrot generate -1,-2,3,2 900,600 100 mandelbrot.png

Notice that default settings are built-in :

$ rust-mandelbrot generate ? ? 100 mandelbrot.png

###draw

The draw command launch the interactive Set Viewer. It starts with a specific frame of the Mandelbrot Set (which you precise in the command arguments), and then you can zoom-in with the mouse (left-click). You can also go back to the original view with the right-click. Like the generate command, the draw command takes a few arguments : the frame of the original view, the image dimensions and the max iterations :

$ rust-mandelbrot draw -1,-2,3,2 900,600 100

Like the generate command, default arguments exist :

$ rust-mandelbrot draw ? ? 100

##TODO

• Optimizations on the draw / generate algorithm
• Use colors to make the set more beautiful :)
• Authorize to change the window's size
• Make a 'zoom out' feature
