3D Surface Subdivision Methods

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.

Modules
	Named Parameters for Subdivision Methods
	In this package, all functions optional parameters are implemented as BGL optional named parameters (see Named Parameters for more information on how to use them).
	Concepts
	Subdivision Methods
	A subdivision method recursively refines a coarse mesh and generates an ever closer approximation to a smooth surface.
