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

Note
Not all rules are implemented!
