[vtkusers] VTK 7.1 vtkDataArray changes, current best way to copy vtkPolyData data?

[Sean McBride]

Hi all,

Since the vtkDataArray changes in VTK 7.1, what is the current best/fastest way to extract the points, strips, and normals from a vtkPolyData into another memory buffer?

I'm always working with the same kind of data, so I'm hoping to preflight the sizes/types and then basically memcpy() the data out.

Thanks,
