## Definition

Refines:
  `AdaptableFunctor` (with two arguments)

See Also
  `CGAL::Direction_2<Kernel>`

## Operations

A model of this concept must provide:
Kernel::Direction_2 | operator() (const Kernel::Direction_2 &d, Orientation o)
| introduces a direction orthogonal to `d`. More...

## Member Function Documentation

Kernel::Direction_2 Kernel::ConstructPerpendicularDirection_2::operator() | ( | const Kernel::Direction_2 & | d,
|  | Orientation | o
| ) |  |

introduces a direction orthogonal to `d`.

If `o` is CGAL::CLOCKWISE, `d` is rotated clockwise; if `o` is CGAL::COUNTERCLOCKWISE, `d` is rotated counterclockwise.

Precondition
  `o` is not CGAL::COLLINEAR.
