CGAL 6.0 - 2D Generalized Barycentric Coordinates
|
A concept that describes the set of requirements of the template parameter GeomTraits used to parameterize all classes and functions with 2D barycentric coordinates from the namespace CGAL::Barycentric_coordinates.

A construction object that must provide the function operator:
FT operator(const Vector_2& v)
that returns the squared length of the vector v.
A predicate object that must provide the function operator:
Orientation operator(const Point_2& p, const Point_2& q, const Point_2& r)
that returns CGAL::LEFT_TURN if r lies to the left of the oriented line l defined by p and q, returns CGAL::RIGHT_TURN if r lies to the right of l, and returns CGAL::COLLINEAR if r lies on l.
