Function ncollide2d::query::closest_points_line_line_parameters

pub fn closest_points_line_line_parameters<N: RealField + Copy>(
    orig1: &Point<N>, 
    dir1: &Vector<N>, 
    orig2: &Point<N>, 
    dir2: &Vector<N>
) -> (N, N)

Closest points between two lines.

The result, say res, is such that the closest points between both lines are orig1 + dir1 * res.0 and orig2 + dir2 * res.1.
