	Line ()
	Constructor. The position is set to (0,0,0) and the direction is set to (1,0,0).
	Line (const Vector3 &p0, const Vector3 &p1)
	Constructor for line passing p0 and p1.
bool	setValue (const Vector3 &p0, const Vector3 &p1)
	Initializes line passing through p0 and p1.

	Returns the distance of point to the line.
const Vector3 &	getPosition () const
	Returns the reference point on the line.
const Vector3 &	getDirection () const
	Returns the direction of the line.
Vector3	getVector (double lambda) const
	Returns a point on line parametrized by lambda.
bool	getClosestPoints (const Line &line2, Vector3 &pointOnLine, Vector3 &pointOnLine2) const

Constructor & Destructor Documentation

Line() [1/2]

ml::Line::Line

(

)

Constructor. The position is set to (0,0,0) and the direction is set to (1,0,0).

Line() [2/2]

ml::Line::Line	(	const Vector3 &	p0,
		const Vector3 &	p1 )

Constructor for line passing p0 and p1.

Member Function Documentation

distance()

double ml::Line::distance

(

const Vector3 &

point

)

const

Returns the distance of point to the line.

getClosestPoint()

Vector3 ml::Line::getClosestPoint

(

const Vector3 &

point

)

const

Returns the point on the line which is closest to point.

getClosestPoints()

bool ml::Line::getClosestPoints	(	const Line &	line2,
		Vector3 &	pointOnLine,
		Vector3 &	pointOnLine2 ) const

Finds the two closest points on this and line2 and stores them in pointOnLine and pointOnLine2, respectively.

Returns true if lines are not parallel.

getDirection()

const Vector3 & ml::Line::getDirection ( ) const

inline

Returns the direction of the line.

Definition at line 53 of file mlLine.h.

getPosition()

const Vector3 & ml::Line::getPosition ( ) const

inline

Returns the reference point on the line.

Definition at line 49 of file mlLine.h.

getVector()

Vector3 ml::Line::getVector ( double lambda ) const

inline

Returns a point on line parametrized by lambda.

Definition at line 57 of file mlLine.h.

References mlrange_cast().

setValue()

bool ml::Line::setValue	(	const Vector3 &	p0,
		const Vector3 &	p1 )

Initializes line passing through p0 and p1.

Returns true if p0 != p1; otherwise, the direction of the line is left unchanged and false is returned.
