CGAL 6.0 - 2D and 3D Linear Geometry Kernel
|
AdaptableTernaryFunction CGAL::Direction_2<Kernel> Operations | |
A model of this concept must provide: | |
| bool | operator() (const Kernel::Direction_2 &d, const Kernel::Direction_2 &d1, const Kernel::Direction_2 &d2) |
returns true iff d is not equal to d1, and while rotating counterclockwise starting at d1, d is reached strictly before d2 is reached. | |
| bool Kernel::CounterclockwiseInBetween_2::operator() | ( | const Kernel::Direction_2 & | d, |
| const Kernel::Direction_2 & | d1, | ||
| const Kernel::Direction_2 & | d2 | ||
| ) |
returns true iff d is not equal to d1, and while rotating counterclockwise starting at d1, d is reached strictly before d2 is reached.
Note that true is returned if d1 == d2, unless also d == d1.
