    • segmentToSegment

      public static double segmentToSegment(Coordinate A, Coordinate B, Coordinate C, Coordinate D)
      Computes the distance from a line segment AB to a line segment CD Note: NON-ROBUST!
      Parameters:
      A - a point of one line
      B - the second point of (must be different to A)
      C - one point of the line
      D - another point of the line (must be different to A)

    • pointToSegmentString

      public static double pointToSegmentString(Coordinate p, Coordinate[] line)
      Computes the distance from a point to a sequence of line segments.
      Parameters:
      p - a point
      line - a sequence of contiguous line segments defined by their vertices
      Returns:
      the minimum distance between the point and the line segments

    • pointToSegment

      public static double pointToSegment(Coordinate p, Coordinate A, Coordinate B)
      Computes the distance from a point p to a line segment AB Note: NON-ROBUST!
      Parameters:
      p - the point to compute the distance for
      A - one point of the line
      B - another point of the line (must be different to A)
      Returns:
      the distance from p to line segment AB

    • pointToLinePerpendicular

      public static double pointToLinePerpendicular(Coordinate p, Coordinate A, Coordinate B)
      Computes the perpendicular distance from a point p to the (infinite) line containing the points AB
      Parameters:
      p - the point to compute the distance for
      A - one point of the line
      B - another point of the line (must be different to A)
      Returns:
      the distance from p to line AB
