# lsystem

[L-System Fractal Generator](https://en.wikipedia.org/wiki/L-system)

This program was inspired by [FractInt](http://fractint.oblivion.cz) pictures and written by me in 2008. Current version (2021) was rewritten in C language and stripped of old/unused/broken code.

# build

```

$ cmake ${source-dir}

$ make

# run

```

$ lsystem -f ${source-dir}/fractals/snoppy.ls

Fractal description parameters:

 | name     | description                                   |

 | ------------- | --------------------------------------------- |

 | alpha         | initial angle                                 |

 | theta         | angle increment in radians                    |

 | angle         | angle increment in degree                     |

 | axiom         | sets axiom                                    |

 | + or -        | increment or decrement angle on theta radians |

 | !             | swaps + and -                                 |

 | [ and ]       | branch                                        |
