const

Returns the closest point on the line to point.

Referenced by closestPoint(), and distance().

closestPoint() [2/3]

Vector3 G3D::Line::closestPoint	(	const Line &	B,
		float &	minDist
	)		const

Finds the closest point to the two lines.

Parameters

minDist

Returns the minimum distance between the lines.

distance()

double G3D::Line::distance ( const Vector3 &  point ) const

inline

Returns the distance between point and the line.

fromPointAndDirection()

static Line G3D::Line::fromPointAndDirection ( const Vector3 &  point, const Vector3 &  direction  )

inlinestatic

Creates a line from a point and a (nonzero) direction.

fromTwoPoints()
