[vtkusers] Can VTK handle 1GB data?

[rakesh patil]

Hi,

Thanks for quick replies. Well, now the question arises, how do I find out
that whether VTK I am using is 32-bi or 64-bit? And if it is not 64 bit,
then how do I get it done to 64-bit? OS I need to find out and confirm

Thanks

Warm Regards
Rakesh Patil
