[Insight-users] Generating a 64 bit version of itk...

[C Heinzl]

Hi,

I'm working in the area of an industrial CT, especially on exact geometry
comparison. So precise data is essential but large data files over 2Gb aren't
easy to handle. Decimating the data would introduce a measurement
error which my partners don't want to have. Currently I use 32 bit in my
testapp which is fine till 650 Mb but later on I should think about a
solution for larger datasets. Therefore I'd like to have a 64 bit version of itk.
Vtk has a switch in cmake called USE_64_IDE or sth like that. Is there sth similar
for itk? Does anybody have some experience in generating a 64 bit itk? 
A first idea if there was no switch would be to replace all the longs by__int64. 
Would that work?
