CGAL 6.0 - 2D and 3D Linear Geometry Kernel
|
AdaptableFunctor Operations | |
A model of this concept must provide: | |
| Kernel::FT | operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::Point_3 &s) const |
returns an approximation of the signed dihedral angle in the tetrahedron pqrs of edge pq. | |
| Kernel::FT Kernel::ComputeApproximateDihedralAngle_3::operator() | ( | const Kernel::Point_3 & | p, |
| const Kernel::Point_3 & | q, | ||
| const Kernel::Point_3 & | r, | ||
| const Kernel::Point_3 & | s | ||
| ) | const |
returns an approximation of the signed dihedral angle in the tetrahedron pqrs of edge pq.
The sign is negative if orientation(p,q,r,s) is CGAL::NEGATIVE and positive otherwise. The angle is given in degrees.
p,q,r and p,q,s are not collinear.
