How to use ?

The CMakeLists file already includes a fetching functionnality in case SFML isn't already installed in your computer. You can directly use the following commands after cloning the project :

cmake -B build          # generates build files
cmake --build build     # compile

Before running, you may need to pay attention to the number of iterations defined in the include/Functions.h directory. The default number of light rays has been set to 300 but you can set it to whichever value you want by changing the defined value of CIRCLE_POINT_COUNT in the Constants.hpp file. After fixing the number of light rays, you can run the visualization using this command :

./build/Fractale        # run
