vooydzig/L-System-python-simulation

Python application for L-System simulations

Installation:

Install additional apps:

Required apps are:

• python 2.6
• pyglet 1.1.4
• rabbyt 0.8.3

Clone to suitable location.

Usage:

Window

Use main.Window class for Your simulations. TODO: add more window methods

Create L-System:

system = LSystem2(start = 'F-F-F-F', lenght = 10, angle = 90, steps = 4, name = 'Sample')

params are:

• start - axiom
• lenght - line lenght in pixels that is used for drawing
• angle - angle in degrees used for rotation
• steps - number of iterations
• name - used when doing screenshots

Add rules:

system.rules = { 'F' = 'FF-F-F-F-FF' }

rules is dictionary used to generate next iterations

use system.simulate() to generate final L-System.

Keyboard:

• 's' - generates screenshoot in gfx/ directory. Name of the screenshoot is: [system.name]_[system.steps].png
• '+' - generate next iteration, add one step
• '-' - generate previous iteration
• '*' - multiply line lenght by 2
• '/' - divide line lenght by 2

Supported operations

Default Constants

• '+' - turn right by given angle
• '-' - turn left by given angle
• '[' - push state to stack, color is set to R-50, G, B-50
• ']' - pop state from stack

Default Variables

• 'F' - draw line from current point in given direction
• 'f' - move from current point in given direction
