CGAL users discussion list

[Ben Supnik <>]

Hi,

If you have a set of line segments you could insert them all into an 
arrangement_2, then analyze the arrangement topologically to detect 
closed regions.  (Or use the arrangement to build a "general polygon 
set" and let the polygon set code find the polygons for you with some 
hints.)

cheers
