Detailed Description

template<typename MeshType, typename RealType = double>
class OpenMesh::Subdivider::Uniform::MidpointT< MeshType, RealType >

Midpoint subdivision algorithm.

With every step, the set of vertices is replaced by the midpoints of all current edges. Then, two sets of faces are created to set up the new connectivity: From all midpoints of edges surrounding an original face, a new face is created. Also, for all midpoints of edges surrounding an original vertex, a new face is created.

Note

This algorithm ignores the _update_points option.

This algorithm is best suited for closed meshes since boundaries tend to fragment into isolated faces after a few iterations.
