Struct LSystem 

pub struct LSystem {
    pub axiom: String,
    pub rules: Vec<LSystemRule>,
    pub angle_increment: f64,
    pub step_size: f64,
}

Lindenmayer system (L-system) for generating fractal geometry strings.

Fields

axiom: String

Axiom (initial string)

rules: Vec<LSystemRule>

Production rules

angle_increment: f64

Angle increment in radians for turtle interpretation

step_size: f64

Step size for turtle movement

Implementations

impl LSystem

pub fn new( axiom: &str, rules: Vec<LSystemRule>, angle_increment_deg: f64, step_size: f64, ) -> Self

Create a new L-system.

pub fn evolve(&self, generations: u32) -> LSystemState

Apply the production rules for n generations.

pub fn interpret(&self, state: &LSystemState) -> Vec<([f64; 2], [f64; 2])>

Interpret the L-system string as turtle graphics commands.

Returns a vector of line segments as pairs of 2D points. Symbols: F = move forward (draw), f = move forward (no draw), + = turn left, - = turn right, [ = push state, ] = pop state.

pub fn koch_curve() -> Self

Create an L-system for the Koch snowflake.

pub fn sierpinski() -> Self

Create an L-system for the Sierpinski triangle.

pub fn dragon_curve() -> Self

Create an L-system for the dragon curve.

pub fn plant_branching() -> Self

Create an L-system for plant branching.

Trait Implementations

impl Clone for LSystem

fn clone(&self) -> LSystem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
