• Segment

public Segment(Vector2D start,
Vector2D end,
double tolerance)
Build a segment.
Parameters:
start - start point of the segment
end - end point of the segment
tolerance - of the line.
• 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
• getLength

public double getLength()
Get the length of the line segment.
Returns:
line segment length.
• 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.
