Detailed Description

Structure of the L-system, which consists of an alphabet of symbols, a collection of production rules and an initial axiom from which to begin the construction.

The constants are implicitly defined by those symbols in the alphabet that are not expanded by any production rule.

In case more than one production rule is available for a given symbol, i.e., a stochastic grammar, a choice is taken according to an uniform probability distribution among the possible rules.

Constructor & Destructor Documentation

Lsystem::Lsystem

(

)

Plain L-system constructor.

Postcondition:

Initialises an undefined L-system (null parameters). This is useless. Use the parametric constructor instead.

Lsystem::Lsystem	(	const set< char > &	vars,
		const string	start,
		const multimap< char, string > &	rules
	)

Parametric L-system constructor.

Parameters:

	vars	The variables.
	start	The initial axiom.
	rules	The production rules.

Precondition:

The L-system definition must be consistent.

Postcondition:

Initialises the defined L-system.

Member Function Documentation

string Lsystem::produce

(

const int

numIter

)

const

Generate a production by iterating the system on the initial axiom.

A stochastic L-system is allowed.

Parameters:

numIter

The number of iterations to run.

Returns:

Sequence of symbols by the end of the iteration.

Precondition:

The parametric L-system must be defined.

Postcondition:

Produces a sequence of symbols by iteration.
