#include <CGAL/Line_arc_3.h>
 
Construct the line segment supported by l, whose source
is p1, and whose target is p2.
 
 
Same.
 




 


 


 
 Constructs the minimum vertex according to the lexicographic ordering of coordinates.  
 
 Same for the maximum vertex. 

 Returns true iff the segment is vertical. 

 


The format for input/output is, for each line arc: a Line_3 (the supporting line) and two Circular_arc_point_3 (the two endpoints), under the condition that the endpoints are actually lying on the line.
