\cgalPkgDesc{Subdivision methods recursively refine a control mesh and generate points approximating the limit surface. This package consists of four popular subdivision methods and their refinement hosts. Supported subdivision methods include Catmull-Clark, Loop, Doo-Sabin and \f$ \sqrt{3}\f$ subdivisions. Their respective refinement hosts are <span class="textsc">Pqq</span>, <span class="textsc">Ptq</span>, <span class="textsc">Dqq</span> and \f$ \sqrt{3}\f$ refinements. Variations of those methods can be easily extended by substituting the geometry computation of the refinement host.}
