Procedural art: Rangolis
turtle package in python makes generating procedural art trivial.
I really want to explore L-systems and fractals. I was thinking of space
filing patterns and I came across a link to kolams or rangolis on wikipedia.
Question: Can I make the (loop-line-)x3(curve-line)x2 pattern?
Surprisingly, this took less than 45 minutes from inspiration to execution.
from turtle import * import numpy as np
Define the loop, and then the rule
granularity = 10 diameter = float(100) straight = diameter/np.sqrt(2.0) dela = 10 def loop(): delay(dela) forward(straight) left(45) circle(diameter/2,180) left(45) delay(dela) forward(straight) def rule(): for _ in range(3): loop() forward(straight) for _ in range(2): #right(45) circle(diameter/2,90) forward(straight) setworldcoordinates(-400,-500,500,200) pensize(3) bgcolor("#302c2b") pencolor("#c98d82") #pencolor("#e8dcda") setheading(135) hideturtle() for _ in range(4): rule() #exitonclick() ts = getscreen() ts.getcanvas().postscript(file='kolam_1.eps')
