Struct poly2tri::Polygon

pub struct Polygon { /* fields omitted */ }

Basic polygon interface

Methods

impl Polygon

This struct implements a polygon. Note that this is currently a wrapper around a c library and as such it's bubbles through some of the underlying implementation details such as panicking on duplicated points.

fn new() -> Polygon

Creates a new empty polygon.

fn from_iterator<'a, I>(points: I) -> Polygon where
    I: Iterator<Item = &'a [f64; 2]>, 

Creates a polygon from an iterator of points.

fn add_point(&mut self, x: f64, y: f64)

Adds a single point to the polygon. These points must not be repeated!

fn get_point(&self, idx: usize) -> [f64; 2]

Looks up a point at a certain index.

fn size(&self) -> usize

Returns the size of the polygon (number of points).

Trait Implementations

impl Drop for Polygon

fn drop(&mut self)

A method called when the value goes out of scope.
