PSLSystem2

public PSLSystem2(java.lang.String grammar,
                  int depth,
                  float angle)

Create a new LSystem that can be written to a PS file with axiom 'F'

Parameters:

grammar - The grammar of the LSystem

depth - The recursive depth of the grammar

angle - The angle distance each turn should make, in degrees

PSLSystem2

public PSLSystem2(java.lang.String axiom,
                  java.lang.String grammar,
                  int depth,
                  float angle)

Create a new LSystem that can be written to a PS file

Parameters:

axiom - The axiom to apply the fractal to

grammar - The grammar of the LSystem

depth - The recursive depth of the grammar

angle - The angle distance each turn should make, in degrees

Method Detail

save

public void save(java.lang.String filename)

Save the LSystem to the named file at dimensions (500, 500)

Parameters:

filename - Filepath to save to

save

public void save(java.lang.String filename,
                 float width,
                 float height)

Save the LSystem to the named file at the specified dimensions

Parameters:

filename - Filepath to save to

width - Width of PostScript (in centimeters?)

height - Height of PostScript (in centimeters?)

drawLine

protected void drawLine(java.lang.Object user,
                        int x,
                        int y,
                        int u,
                        int v)

Execute the LSystem and write its movements to the PS file, scaled to fit the page

Specified by:

drawLine in class LSystem2Renderer

Parameters:

user - Any object the caller wants to pass. This is forwarded on to the drawLine callback
