PairLineIntersection
public enum PairLineIntersection<Vector> where Vector : VectorFloatingPointextension PairLineIntersection: Equatable where Vector: Equatableextension PairLineIntersection: Hashable where Vector: HashableThe result of an intersection test between an arbitrary open shape and a line, specialized for storing at most two intersection points at a time.
-
Represents the case where the line crosses the bounds of the shape on a single point.
Declaration
Swift
case singlePoint(LineIntersectionPointNormal<Vector>) -
Represents cases where the line crosses the shape twice.
Declaration
Swift
case twoPoint(LineIntersectionPointNormal<Vector>, LineIntersectionPointNormal<Vector>) -
Represents the case where no intersection occurs at any point.
Declaration
Swift
case noIntersection -
Returns the list of line intersection point normals referenced by this intersection instance.
Declaration
Swift
public var lineIntersectionPointNormals: [LineIntersectionPointNormal<Vector>] { get } -
Returns the list of point normals referenced by this intersection instance.
Declaration
Swift
public var pointNormals: [PointNormal<Vector>] { get } -
Returns a new
