  • Constructor Details

  • Method Details

    • getPoint

      public Point2D getPoint()

    • getDirection

      public Vector2D getDirection()

    • pointAt

      public Point2D pointAt(Real t)

    • distanceTo

      public Real distanceTo(Point2D p)

    • dimension

      public int dimension()
      Description copied from interface: GeometricObject
      Returns the intrinsic dimension of this geometric object.

      Examples:

      • Point: 0
      • Line/Segment: 1
      • Plane/Surface: 2
      • Volume: 3

      Specified by:
      dimension in interface GeometricObject<Point2D>
      Returns:
      the dimension

    • ambientDimension

      public int ambientDimension()
      Description copied from interface: GeometricObject
      Returns the dimension of the ambient space containing this object.

      For example, a 2D plane in 3D space has dimension=2 but ambientDimension=3.

      Specified by:
      ambientDimension in interface GeometricObject<Point2D>
      Returns:
      the ambient space dimension

    • containsPoint

      public boolean containsPoint(Point2D p)

    • description

      public String description()
      Description copied from interface: GeometricObject
      Returns a human-readable description of this geometric object.
      Specified by:
      description in interface GeometricObject<Point2D>
      Returns:
      description string

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • getNormal

      public Vector2D getNormal()

    • signedDistance

      public Real signedDistance(Point2D p)
      Calculates the signed distance from a point to this line. Positive if on the side of the normal (left/right depending on system), negative otherwise.
      Parameters:
      p - the point
      Returns:
      the signed distance

    • flipped

      public Line2D flipped()
      Returns a flipped version of this line (reverses direction).

    • intersection

      public Point2D intersection(Line2D other)
      Computes the intersection point with another line.
      Parameters:
      other - the other line
      Returns:
      the intersection point, or null if lines are parallel
