[vtkusers] Getting normals from vtkPolyData and accessing coordinates

[Melissa Morrison]

I have been working on a problem for some time now, and was hoping that
someone will be able to shed some light on the situation.

My goal is to find the normals for some poly data, and pass the normals
into an array so that I can access each x-coordinate, y-coordinate and
z-coordinate for every normal for each vertex in the polydata.

Can anyone help??

Thanks.
