pub type SimplePolygon2d<T> = SimplePolygon<T, U2>;

Implementations

impl<T: Real> SimplePolygon2d<T>

pub fn apply_isometry(&self, similarity: &Isometry3<T>) -> SimplePolygon3d<T>

Apply a similarity transform in order to construct a 3D simple polygon.

Each 2D vertex is implicitly assumed to have z coordinate 0.

impl<T> SimplePolygon2d<T>where
    T: Scalar,

pub fn edge_iter<'a>(&'a self) -> impl 'a + Iterator<Item = LineSegment2d<T>>

An iterator over edges as line segments
