Why Use l-system-fractals?

This package includes an base LSystem class with in-built subclasses for common l-system fractals:

• Fractal plant
• Koch curve
• Sierpinski triangle
• Sierpinski arrowhead curve
• Dragon curve

Usage

Sample Code 1

Drawing custom L-Systems using the LSystem Class

from l_system_fractals import *

my_l_system = LSystem(
    iterations=5,
    start="X",
    rules=[("X", "-F+X"), ("F", "-F-[X+F]+F")],
    variable_rules=[("F", DRAW_FORWARD), ("X", MOVE_FORWARD)],
    constant_rules=[("-", TURN_RIGHT), ("+", TURN_LEFT), ("[", SAVE_POS_AND_ANGLE), ("]", GO_TO_POS_ANGLE_AND_RESET_THEM)],
    angle=30,
    scale=2,
    thickness=2,
    start_angle=10
)

my_l_system.draw_turtle(pos=(0, 0), speed=0, end_turtle=True, instant=False, make_colorful=True, color_density=10)

Example 2

Drawing custom L-Systems using subclass of LSystem Class

from l_system_fractals import *

class MyLSystem(LSystem):
    def __init__(self):
        super().__init__(
        iterations=5,
        start="X",
        rules=[("X", "-F+X"), ("F", "-F-[X+F]+F")],
        variable_rules=[("F", DRAW_FORWARD), ("X", MOVE_FORWARD)],
        constant_rules=[("-", TURN_RIGHT), ("+", TURN_LEFT), ("[", SAVE_POS_AND_ANGLE), ("]", GO_TO_POS_ANGLE_AND_RESET_THEM)],
        angle=30,
        scale=2,
        thickness=2,
        start_angle=10
        )

my_l_system = MyLSystem()

my_l_system.draw_turtle(pos=(0, 0), speed=0, end_turtle=True, instant=False, make_colorful=True, color_density=10)

Example 3

Drawing L-System using pre-made classes

from l_system_fractals import *

my_l_system = FractalPlant(iterations=6, start = "X", scale = 3, thickness = 1, start_angle = 0)

my_l_system.draw_turtle(pos=(0, -300), speed=0, end_turtle=True, instant=False, make_colorful=True, color_density=10)

Versions
