Function ncollide2d::query::closest_points_line_line_parameters_eps

pub fn closest_points_line_line_parameters_eps<N: RealField>(
    orig1: &Point<N>, 
    dir1: &Vector<N>, 
    orig2: &Point<N>, 
    dir2: &Vector<N>, 
    eps: N
) -> (N, N, bool)

Closest points between two lines with a custom tolerance epsilon.

The result, say res, is such that the closest points between both lines are orig1 + dir1 * res.0 and orig2 + dir2 * res.1. If the lines are parallel then res.2 is set to true and the returned closest points are orig1 and its projection on the second line.
