## Definition

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

Operations

Only constructors (from 3 scalars and copy constructors) and access methods to coordinates `x()`, `y()`, `z()` are needed.

Has Models:

  `CGAL::Cartesian<FieldNumberType>`

  `CGAL::Simple_cartesian<FieldNumberType>`
