double	get_distance (const Segment3D &s, const Vector3D &p)
	Get the distance between a segment and a point. More...

double	get_distance (const Segment3D &a, const Segment3D &b)
	Get the distance between two segments. More...

const Segment3D &	get_segment_3d_geometry (const Segment3D &g)

Shortest segments
These methods return the shortest segment connecting two geometric objects. Such segments can be used to give the direction of the derivative of the distance between the two objects. The 0 point on the segment is in the first passed object and the 1 point is in the second.
