Class Motion

java.lang.Object
  cdx.Motion

public class Motion
extends java.lang.Object

Objects of the Motion class provide all a-priori known information about what the Aircraft was doing between two frames. Also provides methods to do useful things with this object (so it's not just dead data).

Constructor Summary

Motion()
Constructor

Motion(Aircraft _aircraft, Vector3d _pos)
Initialise with an aircraft and one position.

Motion(Aircraft _aircraft, Vector3d _pos_one, Vector3d _pos_two)
Initialise with an aircraft and two positions.

Method Summary

void	copyfrom(Aircraft _aircraft, Vector3d _pos_one, Vector3d _pos_two) Copy the value of another motion to this motion.
Vector3d	findIntersection(Motion other) Find an intersection between this Motion and another Motion.
Aircraft	getAircraft() Retrieve the aircraft.
Vector3d	getFirstPosition() Retrieve the first position.
Vector3d	getSecondPosition() Retrieve the second position.
java.lang.String	toString() Convert a motion to a string

Constructor

Motion

public Motion(Aircraft _aircraft,
              Vector3d _pos_one,
              Vector3d _pos_two)

Initialise with an aircraft and two positions.

Parameters:

_aircraft - aircraft

_pos_one - first position

_pos_two - second position

Motion

public Motion(Aircraft _aircraft,
              Vector3d _pos)

Initialise with an aircraft and one position.

Parameters:

_aircraft - aircraft

_pos - first position that equals to the second one

Method Detail

getAircraft

public Aircraft getAircraft()

Retrieve the aircraft.

getFirstPosition

public Vector3d getFirstPosition()

Retrieve the first position.

getSecondPosition

public Vector3d getSecondPosition()

Retrieve the second position.

toString

public java.lang.String toString()

Convert a motion to a string

Overrides:

toString in class java.lang.Object

copyfrom

public void copyfrom(Aircraft _aircraft,
                     Vector3d _pos_one,
                     Vector3d _pos_two)

Copy the value of another motion to this motion.

Parameters:

_aircraft - aircraft in the target motion

_pos_one - first position

_pos_two - second position

findIntersection

public Vector3d findIntersection(Motion other)

Find an intersection between this Motion and another Motion.

Returns:

a Vector3d object with the intersection point if an intersection was found, null otherwise.
