## Kernel::ConstructVertex_3

A model for this must provide:

Kernel::Point_3 | fo.operator() ( Kernel::Segment_3 s, int i)
|  | returns source or target of s: fo(s,0) returns the source of s, fo(s,1) returns the target of s. The parameter i is taken modulo 2.
Kernel::Point_3 | fo.operator() ( Kernel::Iso_cuboid_3 c, int i)
|  | returns the i'th vertex of c, as indicated in the figure below. The parameter i is taken modulo 8.

Kernel::Point_3 | fo.operator() ( Kernel::Triangle_3 t, int i)
|  | returns the i'th vertex of t. The parameter i is taken modulo 3.
Kernel::Point_3 | fo.operator() ( Kernel::Tetrahedron_3 t, int i)
|  | returns the i'th vertex of t. The parameter i is taken modulo 4.
