penMesh is a generic and efficient data structure for representing and manipulating polygonal meshes

MyMesh mesh;

// iterate over all vertices
for (MyMesh::VertexIter v_it=mesh.vertices_begin(); v_it!=mesh.vertices_end(); ++v_it) 
   ...; // do something with *v_it, v_it->, or v_it.handle()

// iterate over all halfedges
for (MyMesh::HalfedgeIter h_it=mesh.halfedges_begin(); v_it!=mesh.halfedges_end(); ++v_it) 
   ...; // do something with *h_it, h_it->, or h_it.handle()

// iterate over all edges
for (MyMesh::EdgeIter e_it=mesh.edges_begin(); v_it!=mesh.edges_end(); ++v_it) 
   ...; // do something with *e_it, e_it->, or e_it.handle()

// iterator over all faces
for (MyMesh::FaceIter f_it=mesh.faces_begin(); v_it!=mesh.faces_end(); ++v_it) 
   ...; // do something with *f_it, f_it->, or f_it.handle()
