◆ operator()() [1/3]

Kernel::Point_3 Kernel::ConstructPointOn_3::operator() ( const Kernel::Line_3 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.

◆ operator()() [2/3]

Kernel::Point_3 Kernel::ConstructPointOn_3::operator() ( const Kernel::Ray_3 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.

◆ operator()() [3/3]

Kernel::Point_3 Kernel::ConstructPointOn_3::operator() ( const Kernel::Segment_3 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.
