\ccDefinition
|
|
|
|
\ccClassTemplateName converts objects from the kernel traits \ccc{K1} to
|
|
the kernel traits \ccc{K2}. Those traits must be of the form
|
|
\ccc{Homogeneous<RT1>} and \ccc{Homogeneous<RT2>} (or the equivalent with
|
|
\ccc{Simple_homogeneous}). It then provides the following operators to
|
|
convert objects from \ccc{K1} to \ccc{K2}.
|
|
|
|
The third template parameter \ccc{RT_Converter} is a function object that must
|
|
provide \ccc{K2::RT operator()(const K1::RT &n);} that
|
|
converts \ccc{n} to an \ccc{K2::RT} that has the same value.
|
|
|
|
The default value of this parameter is \ccc{CGAL::NT_converter<K1::RT, K2::RT>},
|
|
which uses the conversion operator from
|
|
\ccc{K1::RT} to \ccc{K2::RT}.
|
|
|
|
Similarly, the fourth template parameter must provide
|
|
\ccc{K2::FT operator()(const K1::FT &n);} that
|
|
converts \ccc{n} to an \ccc{K2::FT} that has the same value. Its
|
|
default value is \ccc{CGAL::NT_converter<K1::FT, K2::FT>}.

{ returns a \ccc{K2::Point_2} which coordinates are those of \ccc{p},
|
|
converted by \ccc{RTConverter}.}
|
|
|

Similar operators are defined for the other kernel traits geometric types
|
|
\ccc{Point_3}, \ccc{Vector_2}...
