Represents an N-dimensional rectangle with a vector describing its origin and a size vector that describes the span of the rectangle.

  • Convenience for Vector.Scalar

    Declaration

    Swift

    public typealias Scalar = Vector.Scalar

  • The starting location of this rectangle with the minimal coordinates contained within the rectangle.

    Declaration

    Swift

    public var location: Vector

  • The size of this rectangle, which when added to location produce the maximal coordinates contained within this rectangle.

    Must be >= Vector.zero

    Declaration

    Swift

    public var size: Vector

  • Initializes a NRectangle with the location + size of a rectangle.

    Declaration

    Swift

    public init(location: Vector, size: Vector)

  • Returns a RoundNRectangle which has the same bounds as this rectangle, with the given radius vector describing the dimensions of the corner arcs.

    Declaration

    Swift

    @inlinable
public func rounded(radius: Vector) -> RoundNRectangle<Vector>

  • Returns a RoundNRectangle which has the same bounds as this rectangle, with the given radius value describing the dimensions of the corner arcs.

    Alias for rounded(radius: Vector(repeating: radius))

    Declaration

    Swift

    public func rounded(radius: Scalar) -> RoundNRectangle<Vector>

Available where Vector: VectorAdditive

  • Returns an empty rectangle

    Declaration

    Swift

    public static var zero: NRectangle { get }

  • Returns true if the size of this rectangle is zero.

    Declaration

    Swift

    public var isSizeZero: Bool { get }

  • Minimum point for this rectangle.

    When set, the maximal point on the opposite corner is kept fixed.

    Declaration

    Swift

    public var minimum: Vector { get set }

  • Maximum point for this rectangle.

    When set, the minimal point on the opposite corner is kept fixed.

    Declaration

    Swift

    public var maximum: Vector { get set }

  • Returns this Rectangle represented as an AABB

    Declaration

    Swift

    public var asAABB: AABB<Vector> { get }

  • Initializes an empty NRectangle instance.

    Declaration

    Swift

    public init()

  • Initializes a NRectangle instance out of the given minimum and maximum coordinates.

    Precondition

    minimum <= maximum

    Declaration

    Swift

    public init(minimum: Vector, maximum: Vector)

  • Returns this Rectangle represented as an AABB

    Declaration

    Swift

    public var bounds: AABB<Vector> { get }

Available where Vector: VectorAdditive & VectorComparable

  • Returns true if size >= .zero.

    Declaration

    Swift

    public var isValid: Bool { get }

  • Initializes a NRectangle containing the minimum area capable of containing all supplied points.

    If no points are supplied, an empty NRectangle is created instead.

    Declaration

    Swift

    public init(of points: Vector...)

  • Initializes a NRectangle out of a set of points, expanding to the smallest bounding box capable of fitting each point.

    Declaration

    Swift

    @inlinable
public init<C>(points: C) where Vector == C.Element, C : Collection

  • Expands the bounding box of this NRectangle to include the given point.

    Declaration

    Swift

    public mutating func expand(toInclude point: Vector)

  • Expands the bounding box of this NRectangle to include the given set of points.

    Same as calling expand(toInclude:) over each point. If the array is empty, nothing is done.

    Declaration

    Swift

    @inlinable
public mutating func expand<S>(toInclude points: S) where Vector == S.Element, S : Sequence

  • Returns whether a given point is contained within this bounding box.

    Points at the perimeter of the N-rectangle (distance to nearest edge == 0) are considered as contained within the N-rectangle.

    Declaration

    Swift

    public func contains(_ point: Vector) -> Bool

  • Returns whether a given NRectangle rests completely inside the boundaries of this NRectangle.

    Declaration

    Swift

    public func contains(_ other: `Self`) -> Bool

  • Returns whether this NRectangle intersects the given NRectangle instance. This check is inclusive, so the edges of the bounding box are considered to intersect the other bounding box’s edges as well.

    Declaration

    Swift

    public func intersects(_ other: `Self`) -> Bool

  • Returns a NRectangle which is the minimum NRectangle that can fit this NRectangle with another given NRectangle.

    Declaration

    Swift

    public func union(_ other: `Self`) -> NRectangle<Vector>

  • Creates a rectangle which is equal to the positive area shared between this rectangle and other.

    If the rectangles do not intersect (i.e. produce a rectangle with < 0 bounds), nil is returned, instead.

    Declaration

    Swift

    @inlinable
public func intersection(_ other: `Self`) -> `Self`?

  • Returns a NRectangle which is the minimum NRectangle that can fit two given Rectangles.

    Declaration

    Swift

    public static func union(_ left: `Self`, _ right: `Self`) -> NRectangle<Vector>

Available where Vector: VectorMultiplicative

  • Returns an NRectangle with location .zero and size .one.

    Declaration

    Swift

    static var unit: `Self` { get }

  • Returns a NRectangle with the same position as this NRectangle, with its size multiplied by the coordinates of the given vector.

    Declaration

    Swift

    @inlinable
func scaledBy(vector: Vector) -> NRectangle<Vector>

Available where Vector: VectorDivisible & VectorComparable

  • Subdivides this rectangle into 2 ^ D (where D is the dimensional size of Self.Vector) rectangles that occupy the same area as this rectangle but subdivide it into equally-sized rectangles.

    The ordering of the subdivisions is not defined.

    Declaration

    Swift

    @inlinable
public func subdivided() -> [`Self`]

Available where Vector: VectorFloatingPoint
