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.
