well, i'm not sure if my answer is enough, because i'm newer also in vtk,
but i think that the polydata is considered as a tree ( cell, edge, vertex),
so in order to modify one of its node ( such vertex), you have to access to
it, modify it, then apply the modification on it locally (
polydata->GetPoints()->modified();) then, apply it to the polydata and
finally update it, in order to visualize the new mesh
