3D Surface Subdivision Methods Reference

Le-Jeng Andy Shiue

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 \( \sqrt{3}\) subdivisions. Their respective refinement hosts are Pqq, Ptq, Dqq and \( \sqrt{3}\) refinements. Variations of those methods can be easily extended by substituting the geometry computation of the refinement host.
