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

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. | |
| Segment3D | get_shortest_segment (const Segment3D &sa, const Segment3D &sb) |
Get the distance between two segments.
Get the distance between a segment and a point.
