## Kernel::ConstructRay_3

A model for this must provide:

Kernel::Ray_3

fo.operator() ( | Kernel::Point_3 p, Kernel::Point_3 q)

|  | introduces a ray with source p and passing through point q.

Kernel::Ray_3

fo.operator() ( | Kernel::Point_3 p, Kernel::Vector_3 v)

|  | introduces a ray with source p and with the direction given by v.

Kernel::Ray_3

fo.operator() ( | Kernel::Point_3 p, Kernel::Direction_3 d)

|  | introduces a ray with source p and with direction d.
Kernel::Ray_3 | fo.operator() ( Kernel::Point_3 p, Kernel::Line_3 l)
|  | introduces a ray with source p and with the same direction as l.
