  • Constructor Details

    • Segment2D

      public Segment2D(Point2D start, Point2D end)
      Creates a 2D segment from two endpoints.
      Parameters:
      start - the start point
      end - the end point

  • Method Details

    • 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

    • getStart

      public Point2D getStart()

    • getEnd

      public Point2D getEnd()

    • midpoint

      public Point2D midpoint()
      Returns the midpoint of this segment.
      Returns:
      the midpoint

    • length

      public Real length()
      Returns the length of this segment.
      Returns:
      the length

    • at

      public Point2D at(Real t)
      Interpolates along the segment.
      Parameters:
      t - the parameter (0 = start, 1 = end)
      Returns:
      the interpolated point

    • containsPoint

      public boolean containsPoint(Point2D p)

    • toSegmentND

      public SegmentND toSegmentND()
      Converts to SegmentND.
      Returns:
      the N-dimensional representation

    • 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

      Overrides:
      toString in class Object

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • hashCode
