[vtkusers] VTK and big dataset

[Amy Henderson]

Hi Luca,

The error message you're getting -- "Update extent does not lie within 
whole extent" -- means that you're requesting data that does not lie within 
the bounds of your data set. Look at the range of z-values you're 
requesting: 0 - 92. In your data set, z ranges from 0 to 69; you won't get 
valid results (and very well may crash your program) if you ask for values 
outside that range.
