Disregarding the argument about whether using shared_ptr is a good idea or not, as explained by the accepted answer, you can use the following if you continue to use shared_ptr:

void addVtx (const Vector3& vt)

}

void setVtx (size_t v, const Vector3& vt)
{
    if ( vtx.size() > 0 && v < vtx.size() )
    {
       vtx[v] = std::make_shared(vt);
    }
}
