Fractal Renderer

This is a program used to render fractals using a RON parameter file. It also has a very simple gui for an easier navigation.

How to install

If you have cargo installed:

cargo install fractal_rndr

Otherwise, you can download the latest executable from the releases tab.

How to use

Create a RON parameter file with the following structure (see parameter file reference and preset renders):

Frame((
    img_width: 1920,
    img_height: 1080,

    zoom: 0.000053,
    center_x: -0.1159076,
    center_y: -0.000022,
    fractal: ThirdDegreeRecWithGrowingExponent,

    max_iter: 2000,

    coloring_mode: MinMaxNorm(
        min: Custom(200),
        max: Custom(750),
        map: Linear,
    ),
    sampling: (
        level: Ultra,
        random_offsets: true,
    ),
))

Note: If the parameter file doesn't exist, it will be created automatically with default values.

Then, either ...

• ... render the fractal:

  fractal_rndr path/to/param_file.ron path/to/output_image.png
  

  Alternatively, if you have rust installed and downloaded this repository:

  cargo run -r -- fractal.ron fractal.png
  

• ... start the gui using the --gui option:

  fractal_rndr path/to/param_file.ron path/to/output_image.png --gui
  

  The app looks like this:

  

Note: Supported image formats are png and jpg (the extension is used to guess the format)
