Polygon

public struct Polygon : PolygonProtocol
extension Polygon: Additive
extension Polygon: Equatable
extension Polygon: CustomStringConvertible

Polgonal shape containing at least three vertices.

  • Note

    In the case that this Polygon is convex, the ConvexPolygonContainer is initialized with it. In the case the this Polygon is concave, it is broken up into the minimum number of triangles through an Ear Clipping method.

    Declaration

    Swift

    public var collisionDetectable: ConvexPolygonContainer { get }

    Return Value

    ConvexPolygonContainer that can be used for collision detection.
