Trait mgf::Polygon

pub trait Polygon: Shape {
    type FaceType: Collider<Contains, Point3<f32>> + Into<Plane> + Clone;
    fn num_vertices(&self) -> usize;
    fn vertex(&self, _: usize) -> Point3<f32>;

Polygons are objects composed of edges and vertices that can accurately describe whether or not they contain a point.

Associated Types

type FaceType: Collider<Contains, Point3<f32>> + Into<Plane> + Clone

Type of the face object the polygon returns.

Required Methods

fn num_vertices(&self) -> usize

The number of edges available to query.

fn vertex(&self, _: usize) -> Point3<f32>

Returns the ith vertex as a Point.

fn num_edges(&self) -> usize

The number of edges available to query.

fn edge(&self, _: usize) -> (usize, usize)

Returns the ith edge of the polygon as a pair of indices.

fn face(&self) -> &Self::FaceType
