Member Function Documentation

double Line3::closestPoint

(

const Coord3 &

point

)

const

Returns:

the point on the line that is closest to the given point

bool Line3::closestPoint	(	const Line3 &	line,
		double &	t_this,
		double &	t_line
	)			const

Returns:

the t for the point point on the line that is closest to the given line
