Operations
A model of this concept must provide:
Kernel::Vector_3	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r)
	computes the unit normal of the vectors q-p and r-p. More...

operator()()

Kernel::Vector_3 Kernel::ConstructUnitNormal_3::operator()	(	const Kernel::Point_3 &	p,
		const Kernel::Point_3 &	q,
		const Kernel::Point_3 &	r
	)

computes the unit normal of the vectors q-p and r-p.

This requires that Kernel::FT supports the sqrt operation.
