[vtkusers] Reading data from the GUI level

[Mathieu Malaterre]

This is a nice feature of VTK. You can store structured points 
containing not only scalar but vectors !

So I assume you are reading only scalar structured points, right ?

You'll have to use it this way:

reader->GetOutput()->GetScalarComponentAsFloat( x, y, z, 0)
for pixel x,y,z
