Detailed Description

A class to draw Lindenmayer Systems.

Constructor & Destructor Documentation

Lindenmayer()

Lindenmayer::Lindenmayer ( string  axiom, int  iterations  )

inline

Constructor method to initialise values of Lindenmayer object.

The constructor takes in axiom and number of iterations as a parameter and sets some default values for other fields

Parameters

axiom	The axiom for L-System
iterations	Number of times the given rules have to be applied to the axiom

Member Function Documentation

addRule()

void Lindenmayer::addRule ( string  rule )

inline

A method to add rules to the L-System.

Parameters

rule	The rule which has to be applied to the axiom. Rule should be of the form "X=ABCDEF" if X has to be replace with ABCDEF in subsequent iterations

draw()

void Lindenmayer::draw ( double  colors[][3] = NULL )

inline

A method to draw the L-System given the axiom and set of rules.

Parameters

colors

A 2-D array of colors which has to be passed to the function. A sample array of 2 colors is {{r1, g1, b1}, {r2, g2, b2}} where r, g, b are the red, green, blue values for a color respectively

getAngle()

double Lindenmayer::getAngle ( )

inline

A method to get the current rotation angle of turtle on screen.

getAxiom()

string Lindenmayer::getAxiom ( )

inline

A method to get the axiom of current L-System.

getBranchLength()

double Lindenmayer::getBranchLength ( )

inline

A method to get the current branch length of L-System.

getBranchScaleFactor()

double Lindenmayer::getBranchScaleFactor ( )

inline

A method to get the current value of branchScaleFactor.

getPointScaleFactor()

double Lindenmayer::getPointScaleFactor ( )

inline

A method to get the current value of pointScaleFactor.

getPointSize()

double Lindenmayer::getPointSize ( )

inline

A method to get the current value of point size.

getX()

int Lindenmayer::getX ( )

inline

A method to get the current X-Coordinate of turtle on screen.

getY()

int Lindenmayer::getY ( )

inline

A method to get the current Y-Coordinate of turtle on screen.

setAngle()

void Lindenmayer::setAngle ( double  angle )

inline

Setter method for setting the rotation angle of the turtle corresponding to + and - in the generation string.

Initial rotation angle = 20 degrees

Parameters

angle

The rotation angle for L-System in degrees

setBranchLength()

void Lindenmayer::setBranchLength ( double  branchLength )

inline

Setter method for setting the number of pixels the turtle moves in one step.

Initial branch length = 100px

Parameters

branchLength

The branch length for L-System

setBranchScaleFactor()

void Lindenmayer::setBranchScaleFactor ( double  branchScaleFactor )

inline

Setter method for setting the factor with which the branch length is multiplied whenever branching off at a point.

Initial branch scale factor = 0.75

Parameters

branchScaleFactor

The branch scale factor for L-System

setPointScaleFactor()

void Lindenmayer::setPointScaleFactor ( double  pointScaleFactor )

inline

Setter method for setting the factor with which the point size is multiplied whenever branching off at a point.

Initial point scale factor = 1.0

Parameters

pointScaleFactor

The point scale factor for L-System

setPointSize()

void Lindenmayer::setPointSize ( double  pointSize )

inline

Setter method for setting the initial point size.

Initial point size = 1.0

Parameters

pointSize

The point size for L-System

setX()

void Lindenmayer::setX ( int  x )

inline

Setter method for setting the current X-Coordinate of drawing turtle on screen.

Initial X-Coordinate = 0

Parameters

x	The new X-Coordinate

setY()

void Lindenmayer::setY ( int  y )

inline

Setter method for setting the current Y-Coordinate of drawing turtle on screen.

Initial Y-Coordinate = 0

Parameters

y	The new T-Coordinate
