Constructor Detail

LSystem2Renderer

public LSystem2Renderer(java.lang.String axiom,
                        java.lang.String grammar,
                        int depth,
                        float angle)

Create a new renderable LSystem

Parameters:

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

setDimension

public void setDimension(float width,
                         float height)

Set the width and hight to scale the render to. All calls to drawLine will have (x u) and (y v) inside the range [0..width) and [0..height)

Parameters:

width -

height -

render

public void render(java.lang.Object user)

Render the LSystem, calls on drawLine to do actual drawing

Parameters:

user - User object that is passed to drawLine

drawLine

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

getDerivedGrammar

public java.lang.String getDerivedGrammar()

Get the grammar expanded to the specified depth

Returns:

the grammar expanded to the specified depth
