@ -69,11 +69,16 @@ In fact, the spherical kernel is documented as a concept,
\item {} and a predefined kernel \ccc{Exact_spherical_kernel_3}. \item {} and a predefined kernel \ccc{Exact_spherical_kernel_3}.
\end{itemize} \end{itemize}
\section{Example} \section{Examples}
This example shows how to construct spheres and compute intersections on them. The first example shows how to construct spheres and compute
intersections on them using the global function.

The second example illustrates the use of a functor.
