This is a simple program to generate images of fractals. Right now it allows for Mandelbrot, Julia, and burning ship fractals, but I plan to add more.
- OpenCV for C++
It may additionally be necessary to change the CMAKE_C_COMPILER and CMAKE_CXX_COMPILER values in CMakeLists.txt if clang and clang++ are not available.
git clone https://github.com/qscgy/fractals-redux
cd fractals-redux
mkdir build
cd build
Now build the program:
cmake ..
make
To use this software, run it from the command line like so:
$ ./Fractal <path to config file> <optional directory to save to on exit>
The config file is a list of key-value pairs, one per line, formatted as <key>=<value>. No spaces. For every fractal the following fields are required (with example values):
formula=mandelbrot
res=300
xmin=-2.5
xmax=1.5
ymin=-1.5
ymax=1.5
In order to zoom in on a region, click once in the top-left corner of the desired window, and again in the lower-right corner. The window will automatically resize and zoom so it displays the part of the fractal in that bounding box.
To reset the view to the original bounds and window size, right-click anywhere.
There is an optional parameter cmap that sets the colormap used. Right now the following colormaps are supported (not case sensitive):
- grayscale
- magma
- rainbow
- grape
If a value for cmap is not specified, the default is grayscale.
