you might want to balance your SETs and GETs.
use a SETsomething for your data, and GETthe_same_thing then to read it.
example with vectors:
ReadVectorArray = pdata.GetPointData().GetVectors();
if you only associate one Vector array to your polydata, that should be
enough. Otherwise, use names to differentiate them.
