Detailed Description

template<typename MeshType, typename RealType = float>
class OpenMesh::Subdivider::Uniform::CompositeT< MeshType, RealType >

This class provides the composite subdivision rules for the uniform case.

To create a subdivider derive from this class and overload the functions name() and apply_rules(). In the latter one call the wanted rules.

For details on the composite scheme refer to

P. Oswald, P. Schroeder "Composite primal/dual sqrt(3)-subdivision schemes", CAGD 20, 3, 2003, 135–164

Note: Not all rules are implemented!
