Detailed Description
This funny bounding volume is an infinite line with no thickness and extending to infinity in both directions.
Note that it *always* extends in both directions, despite the fact that you specify two points to the constructor. These are not endpoints, they are two arbitrary points on the line.

virtual |
Virtual downcast method.
Returns this object as a pointer of the indicated type, if it is in fact that type. Returns NULL if it is not that type.
Reimplemented from BoundingVolume.

◆ get_point_a()
|
inline |
Returns the first point that defines the line.
Definition at line 39 of file boundingLine.I.
◆ get_point_b()
|
inline |
Returns the second point that defines the line.
