# L-Systems Exploration

A simple L-System generator written in pure Python, with a PySide2 / Qt GUI front-end. This project started out as a
side-exploration into space filling curves and plant/tree generation.

Run ```src/main_gui.py```. There is no need to run the Makefile, except for running the tests and rebuilding the GUI (Unix-likes only).

## L-Systems

You can find the axioms, rules and angles for each l-system in the ```src/data/lsystems.json``` file.
Some of the featured l-systems may be unstable - their shapes maybe inverted or other irregularities will
appear between odd and even iteration depths.

### Space filling curves

Hilbert curve
Hilbert curve variation

Peano curve
FASS curve 1
FASS spiral
Quadratic Gosper curve

FASS curve 0
FASS curve 2

### Trees

Most tree l-systems are from Lindenmayer, A. and Prusinkiewicz, P. (1990) *The Algorithmic Beauty of Plants*.

Houdini Tree
Tree X
Tree B

Tree C
Tree D
Tree E

Tree Y
Tree F
Tree A

### Circular Shapes & Snowflakes

Note: the Gosper's curve is also a space filling curve.
