Member Function Documentation

double ml::Line::distance

(

const Vector3 &

point

)

const

Returns the distance of point to the line.

Vector3 ml::Line::getClosestPoint

(

const Vector3 &

point

)

const

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

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

Find the two closest points on this and line2 and store them in pointOnLine and pointOnLine2, respectively.

Return true if lines are not parallel.

const Vector3& ml::Line::getDirection

(

)

const [inline]

Return the direction of the line.

Definition at line 47 of file mlLine.h.

const Vector3& ml::Line::getPosition

(

)

const [inline]

Return the reference point on the line.

Definition at line 43 of file mlLine.h.

Vector3 ml::Line::getVector

(

double

lambda

)

const [inline]

Return point on line parametrized by lambda.

Definition at line 51 of file mlLine.h.

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

Initialize line passing through p0 and p1.

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