Kernel::ConstructOrthogonalVector_3 Concept Reference

Definition

Operations

A model of this concept must provide:

Kernel::Vector_3 operator() (const Kernel::Plane_3 &p)
 returns a vector that is orthogonal to the plane p and directed to the positive side of p.
 
Kernel::Vector_3 operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r)
 returns a vector that is orthogonal to the plane defined by Kernel::ConstructPlane_3()(p, q, r) and directed to the positive side of this plane.
