\paragraph{Smallest enclosing spheres} are commonly used as bounding
volumes, for example, to speed up intersection tests.

\begin{tabular}{l|ll}
  \textbf{smallest enclosing sphere} & \texttt{double} & exact
    \texttt{qmpq} (non opt.)\\\hline
  Bunny     & 0.02 &  10 \\
  Lion vase & 0.11 & 231 \\
  David     & 0.23 & 126 \\
  Raptor    & 0.6  & 370
\end{tabular}
