[vtkusers] Vertex data in polydata

[Eugene Kim]

Hi everyone,

 	I've been looking for a way to grab attribute data other than your 
basic cells from vtkPolyData.  Using the regular methods, I cannot pull 
out any of the data that is supposedly there, namely vertex data ( and 
others ).
 	I know I can pry the vertices out of the triangle cell data, but 
this really ought to be working properly.  I have a feeling this could be 
due to the fact that i'm reading from different file formats such as .g, 
.vtk.  I've seen other threads about this issue, but most people there 
seem to be getting their primitives from vtkSphereSource or whatnot.
 	Has anyone come across a similar issue?  Am i stupid and is the 
data really there?

Thanks,
Eugene Kim
