Detailed Description

template<class T>
class PLib::NurbsSubSurface< T >

A class to represent a NURBS surface suitable for subdivision.

This class adds the methods and the information necessary for performing subdivision on the surface.

Subdivision is mainly used to output the surface in diverse formats such as VRML, Post-Sript or a mesh file.

This class is based on code from the article "Tessellation of NURB Surfaces" by John W. Peterson, jp@blowfish.taligent.com in "Graphics Gems IV", Academic Press, 1994
