Kernel::Point_3
|
fo.operator() ( 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.

Kernel::Point_3
|
fo.operator() ( Kernel::Plane_3 h)
|
| |
returns an arbitrary point on h.

|
Kernel::Point_3
|
fo.operator() ( 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.
|
|
|
Kernel::Point_3
|
fo.operator() ( 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.
