Class Lindenmeyer

java.lang.Object

net.paulhertz.pixelaudio.Lindenmeyer

public class Lindenmeyer
extends Object

Implements a simple Lindenmeyer system (L-system), a so-called DOL-system: deterministic and context-free. Load production strings into transTable with put(), retrieve them with get(). Was used by Hilbert curve generation until I sped it up more optimized methods.

Lindenmeyer

public Lindenmeyer()

Creates a new Lindenmeyer instance;

Method Details

get

public String get(String clef)

Gets a value from the transition table corresponding to the supplied key.

Parameters:

clef - a single-character String

Returns:

value corresponding to the key

put

public void put(String clef,
 String value)

Loads a key and its corresponding value into the transition table.

Parameters:

clef - a single-character String

value - the String value associated with the key

expandString

public void expandString(ArrayList<String> tokens,
 int levels,
 ArrayList<String> sb)

hilbert

public ArrayList<String> hilbert(int depth)

Encode strings representing a Hilbert curve to supplied depth. To draw the actual curve, ignore the R and L symbols + : 90 degrees CW - : 90 degrees CCW F : forward (n) units

loadAnimSteps

public int[] loadAnimSteps(Lindenmeyer.AnimStepper stepper)
