Detailed Description

template<class TAPosition>
class ug::GlobalSubdivisionMultiGridRefiner< TAPosition >

Specialization of the GlobalMultiGridRefiner class to incorporate subdivision refinement.

Each step of global refinement is subsequently followed by a vertex smoothing pass determined by a user-specified subdivision scheme.

Currently this only works in 2d and 3d.
