Kernel::ConstructPointOn_2

Kernel::Point_2	fo.operator() ( Kernel::Line_2 l, int i)
		returns an arbitrary point on l. It holds point(i) == point(j), iff i==j. Furthermore, is directed from point(i) to point(j), for all i $$< j.
Kernel::Point_2	fo.operator() ( Kernel::Ray_2 r, int i)
		returns a point on r. point(0) is the source, point(i), with $$i>0, is different from the source. Precondition:  $$i 0.
Kernel::Point_2	fo.operator() ( Kernel::Segment_2 s, int i)
		returns source or target of s: point(0) returns the source of s, point(1) returns the target of s. The parameter i is taken modulo 2, which gives easy access to the other end point.
