LocalKernel Concept Reference
Concepts

Definition

The concept LocalKernel describes the set of requirements to be fulfilled by any class used to instantiate the second template parameter of the class CGAL::Monge_via_jet_fitting<DataKernel,LocalKernel,SvdTraits>.

This concept provides the geometric primitives used for the computations in the class CGAL::Monge_via_jet_fitting.

Requirements

In the class CGAL::Monge_via_jet_fitting the scalar type, LocalKernel::FT, must be the same as that of the SvdTraits concept : SvdTraits::FT.

The type LocalKernel::FT is a model of the FieldWithSqrt concept.

Operations

The scalar type LocalKernel::FT must be a field type with a square root.

Only constructors (from 3 scalars and copy constructors) and access methods to coordinates x(), y(), z() are needed for the point and vector types.

Has Models:

CGAL::Cartesian<FieldNumberType>

CGAL::Simple_cartesian<FieldNumberType>
