Lindenmayer system visualizer in Clojure

Lindenmayer system visualizer in Clojure

The curves defined in this program are of the form

1. initial state,
2. replacement rule,
3. angle (for the angle change operator - or +)
4. initial angle

In code, the Koch curve would look like:

;Koch curve
(def koch-curve
  {:init  [:f :- :- :f :- :- :f]
   :rules {:f [:f :+ :f :- :- :f :+ :f]}
   :theta 60
   :init-angle 0})

Running the visualizer

It is assumed that you are using lein to build your Clojure.

1. Download Xming X Server.
2. To test that Xming is working, run sudo apt-get install x11-apps, export DISPLAY=:0, and finally xeyes.
3. You'll know what xeyes is when you see it.
4. Note: Though you won't always need to test whether Xming is working after the first time, you must run
   export DISPLAY=:0 every new command line session for running this code.
5. Once you confirm that Xming is working, compile the code in lein repl with (ns l_system_lab.core) and
   (use 'l_system_lab.core :reload-all).
