Fractal generator?

gray53 · 10-06-2009, 04:45 PM

How would you go about generating a fractal based on something similar to these rules?

1. Start with a vertical line segment of length x
2. Construct a line segment of length nine tenths x starting two thirds of the way up the first line segment at a 15 degree angle to the first line segment.
3. Repeat

Thanks

edit: preferably runs on Vista

Google spits out xfractint as a possible fractal generation program. Not sure if it'll help your case or not...

Do you look for a program that does that? Or do you wanna write a program that does that?

I am looking for a program. Thanks, I should have been more specific.

Check out XaoS*. I think it does what you want*.

Here's a little python script to produce the fractal. It works under Linux and Windows 7 so should under Vista. Obviously you'll need to install Python on Vista but this shouldn't be a problem. This is very simple and only produces 70 iterations but you can easily tune it.

Code:

#!/bin/python
import turtle
turtle.reset()
len=300
loops=70
turtle.setup(width=.60,height=.90)
turtle.up()
turtle.sety((-turtle.window_height()/2)+10)
turtle.setx((turtle.window_width()/2)-10)
turtle.down()
turtle.speed("fastest")
turtle.setheading(90)
for i in range(loops):
	turtle.forward(len)
	turtle.backward(len/3)
	len*=(9.0/10)
	turtle.left(15)
raw_input("Strike a key to continue")

It may be easier just playing with the settings in the script rather than programming a Matlab plot or similar.

The fractal that you're describing lies in a class of fractals called 'IFS', short for 'Iterated Fractal Systems'. Try googling for 'IFS' and 'windows' and I'd bet that you'd find something that would work for you... or you could install python ;-)
