Constructor Detail

• Segment

  public Segment(Vector2D start,
         Vector2D end,
         Line line)

  Build a segment.

  Parameters:

  start - start point of the segment

  end - end point of the segment

  line - line containing the segment

Method Detail

• getStart

  public Vector2D getStart()

  Get the start point of the segment.

  Returns:

  start point of the segment

• getEnd

  public Vector2D getEnd()

  Get the end point of the segment.

  Returns:

  end point of the segment

• getLine

  public Line getLine()

  Get the line containing the segment.

  Returns:

  line containing the segment

• distance

  public double distance(Vector2D p)

  Calculates the shortest distance from a point to this line segment.

  If the perpendicular extension from the point to the line does not cross in the bounds of the line segment, the shortest distance to the two end points will be returned.

  Algorithm adapted from: Thread @ Codeguru

  Parameters:

  p - to check

  Returns:

  distance between the instance and the point
