[vtkusers] VTK 7.0 - Modified meshes is not updated like in the previous versions of VTK

[Ken Martin]

Make sure you call Modified() on what you change in the polydata.  If you
changed the points then do a

polydata.GetPoints().Modified();

if you changed the cells then do something like

polydata.GetPolys().Modified();

most often that is the problem. Folks directly change some part of the
polydata but only call modified at the top.

Thanks
Ken
