\section DecimaterLock Block vertices from beeing touched by the Decimater
You could mark vertices as locked, which should not be modified by the decimater.
\code
// That might be already requested
mesh_->request_vertex_status();
// Get an iterator over all halfedges
Mesh::HalfedgeIter he_it, he_end=mesh_->halfedges_end();
// If halfedge is boundary, lock the corresponding vertices
for (he_it = mesh_->halfedges_begin(); he_it != he_end ; ++he_it)
if (mesh_->is_boundary(*he_it) ) {
mesh_->status(_mesh->to_vertex_handle(*he_it)).set_locked(true);
mesh_->status(_mesh->from_vertex_handle(*he_it)).set_locked(true);
}
\endcode
