                    init(center:radiusX:radiusY:)

Declaration

Swift

init(center: Vector, radiusX: Scalar, radiusY: Scalar)

contains(x:y:)
Returns true if the point described by the given coordinates is contained within this ellipse.

The method returns true for points that lie on the outer perimeter of the ellipse (inclusive)
Declaration
Swift

func contains(x: Scalar, y: Scalar) -> Bool

Available where `Vector`: `VectorFloatingPoint`

foci()
Computes the focal points of this 2D ellipse, as two vectors in space that form pins-and-string construction method for the ellipse.
Declaration
Swift

func foci() -> (a: Vector, b: Vector)
