\ccFunction{bool do_intersect(Type1<R> obj1, Type2<R> obj2);} {checks
  whether \ccc{obj1} and \ccc{obj2} intersect.  Two objects
  \ccStyle{obj1} and \ccStyle{obj2} intersect if there is a point
  \ccStyle{p} that is part of both \ccStyle{obj1} and \ccStyle{obj2}.
  The \ccHtmlNoLinksFrom{intersection} region of those two objects is
  defined as the set of all points \ccStyle{p} that are part of both
  \ccStyle{obj1} and \ccStyle{obj2}.  \ccPrecond the objects are of
  the same dimension.}

The types \ccStyle{Type1} and \ccStyle{Type2} can be any of the following:
\begin{itemize}\ccTexHtml{%
\itemsep0pt\topsep0pt\partopsep0pt\parskip0pt\parsep0pt}{}
\item \ccStyle{Point_d<R>}
\item \ccStyle{Line_d<R>}
\item \ccStyle{Ray_d<R>}
\item \ccStyle{Segment_d<R>}
\item \ccStyle{Hyperplane_d<R>}
