<p>Those traits must be of the form <code><a class="el" href="structCGAL_1_1Homogeneous.html" title="A model for a Kernel using homogeneous coordinates to represent the geometric objects.">Homogeneous</a><RT1></code> and <code><a class="el" href="structCGAL_1_1Homogeneous.html" title="A model for a Kernel using homogeneous coordinates to represent the geometric objects.">Homogeneous</a><RT2></code> (or the equivalent with <code><a class="el" href="structCGAL_1_1Simple__homogeneous.html" title="A model for a Kernel using homogeneous coordinates to represent the geometric objects.">Simple_homogeneous</a></code>). It then provides the following operators to convert objects from <code>K1</code> to <code>K2</code>.</p>
<p>The third template parameter <code>RTConverter</code> is a function object that must provide <code>K2::RT operator()(const K1::RT &n);</code> that converts <code>n</code> to an <code>K2::RT</code> that has the same value.</p>
<p>The default value of this parameter is <code><a class="elRef" href="../Number_types/structCGAL_1_1NT__converter.html">CGAL::NT_converter</a><K1::RT, K2::RT></code>, which uses the conversion operator from <code>K1::RT</code> to <code>K2::RT</code>.</p>
<p>Similarly, the fourth template parameter must provide <code>K2::FT operator()(const K1::FT &n);</code> that converts <code>n</code> to an <code>K2::FT</code> that has the same value.
