Concepts

conceptExtendedKernelTraits_2
 ExtendedKernelTraits_2 is a kernel concept providing extended geometryIt is called extended geometry for simplicity, though it is not a real geometry in the classical sense. Let K be an instance of the data type ExtendedKernelTraits_2. The central notion of extended geometry are extended points. An extended point represents either a standard affine point of the Cartesian plane or a non-standard point representing the equivalence class of rays where two rays are equivalent if one is contained in the other.
