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.

Member Function Documentation

operator()()

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 != CGAL::COLLINEAR.
